May 2nd, 2019 Season 2 Patch 3

iRacing BETA Interface – (01.00.29-beta)

– The maximum limit of Incidents has been increased to 260 for User-Created Sessions.

– In all cases, the Register button now features a split dropdown menu, and includes Watch and Spot.

– – This fixes an issue that was preventing the Watch option from appearing unless the session had at least one entrant looking for a Spotter.

– When running a Test Drive Session from a Multiclass Series, the car selector should now correctly appear before you start the Test Drive Session.

– – After you have made a selection, this choice is saved, should you exit and return.

– Cars that are a part of two different classes are not added to a User-Created Session twice when the second class is added if the car was already added with the first class.

– All Dirt Oval and Dirt Road tracks now feature “Dirt Oval” or “Dirt Road” informational bubbles.

– Track list filters for “Dirt Oval” and “Dirt Road” have been added.

– All tracks’ Number of Configs informational bubble should now be correct.

– When selecting a track while using Grid View, the track names are no longer appended with a track configuration name when the “Show All Configs” option is toggled off.

– Fixed an issue where a user’s name was not updated correctly in the iRacing BETA Interface after a name change.

– The “Welcome” message has returned to the Home section of the iRacing BETA Interface. Welcome back!

– The gradient overlay covering the bottom portion of the featured News article has returned to help increase the legibility of the text.

– Track logos are now always centered in the Track box.

– Fixed an issue with some track info not displaying correctly; particularly trademark symbols.

– Fixed an issue where the Chili Bowl was missing a track image.

 

Official Series

– Fixed an issue where some users were getting stuck registering for the first event of a new race-week, and missing the event.

– – Open Practices for a given Race Week are now started prior to general registration being allowed for the first sessions of that week. Now, when you register for the first Race of the new week during a race-week transition, there are Open Practice servers available into which you can be placed while waiting for your race to start at its scheduled time.

 

Rendering

– Fixed an issue where strange green glowing patterns could appear instead of bright reflections in environment maps.

 

Virtual Reality

– A new option, “AlignmentFix” has been added to the “[OpenVR]” section of the “RendererDX11.ini” file.

– – This option enables various workarounds for vertically misaligned per-eye images in VR (with SPS enabled for GTX1000s). In particular the fix is intended for OpenVR HMDs that make display alignment corrections via modifying the right eye’s frustum’s top/bottom  to be different than the left eyes to shift the image in one eye to align better with the other eye. This sort of oblique projection/Y-offset correction provided by OpenVR is incompatible with SPS on 1080’s when different per eye, and causes visual alignment mismatches with the parts of the scene that render using SPS. This workaround provides several modes of operation, because different headsets and GPUs seem to be having different issues; we suspect some have bad calibration/fixes set by the factory causing issues with SPS off).

– – – Mode 0 = Off.

– – – Mode 1 = Overwrite the right eye’s frustum’s top/bottom with the left eye’s frustum, removing the correction (only enabled when SPS is enabled on a GTX1000 series).

– – – Mode 2 = As Mode 1, but operates even when SPS is disabled and also does it for all GPUs (removes all corrections).

– – – Mode 3 = As Mode 1, but also adjusts the right eye’s viewport to re-apply the original correction factors that were in the projection, in a way that is compatible with SPS (makes corrections work as intended on a GTX1000 w/SPS).

 

– A new option, “MirrorViewVerticalShiftPct” has been added to both the “[Oculus Rift]” and the “[OpenVR]” sections of the “RendererDX11.ini” file.

– – This option shifts the VR mirror image up and down, allowing the image to pan vertically when parts of the image are clipped off the edges of the window.

CHANGE LOGS: 
iRacing BETA Interface – New Features 

– “Vehicle Damage” is now a toggleable option when creating Hosted Sessions and Test Sessions via the “Car Options” dropdown. 
– – You can toggle damage ON (default) or OFF within the Car Options section of the Cars card. 
– – With vehicle damage disabled, all vehicles in the session are indestructible, and will take no damage at all from any sources. Being invulnerable also means your vehicle performance will never be adjusted from collisions, such as changes in aerodynamics or vehicle weight that might normally result from an impact. 
– – – For any and all iRacing Series (Ranked and Unranked), Practices, Qualifiers, Time Trials, Time Attack, and other non-user created racing events, vehicle damage will remain ON. This feature is designed for use in Hosted Sessions and Test Drive only. 

– “Disable Decals & Numbers” is now a toggleable option when creating Hosted Sessions and Test Sessions via the “Car Options” dropdown. 
– – With this option enabled, car numbers and car decals applied via the Paint Kit will not be displayed. Stockcar contingencies will also be removed. 

– The Filtering and Sorting toolbar has been upgraded, separating filters into 3 different sections: 
– – Sort = Orders the displayed information. 
– – Categories = Filters by selected items. 
– – Tags = Filters in ANY or ALL selected items. 

– Race registration has been updated, and any errors that occur should be displayed more clearly. 
– – These errors most often occur when trying to register for a Session for which you are already registered using a different car. 

– For all Table Views, each column header can now be clicked to sort the table by the values of that column. 
– – These sorts are saved when leaving the screen, or exiting the application. 

– License restrictions for joining a Session no longer apply to Spectators. 

– A new error modal window has been implemented that will catch some errors and display them. 

iRacing BETA Interface – Current Series 

– The Official Series section has been redesigned and optimized so that browsing the available Series is now faster and easier than ever before! 
– – Users now have a page with all Current Series for the season displayed. 
– – Clicking on any Series opens the Series modal window, which contains all available Sessions, a list of entries, schedule, and series information. 
– – – Join an Official Session for the Series by selecting a Session to join. 
– – – Click on “Entries” to see a list of all currently registered entrants, where you can spot, spectate, or join the session as a driver. 
– – – “Schedule” and “Series Info” have all the details on the Series. 
– – These changes result in dramatic performance improvements, and have been made to fix stuttering and responsiveness. 

– Additional Current Series improvements include: 
– – The “Search” function has been optimized. 
– – Additional filtering options are now available at the top-right. 
– – Tag filters can be set to match ALL selected Tags, or set to match ANY selected Tags in the dropdown menu. 
– – – You can filter by Session details, such as if the Session is populated, has spectators, has friends, or has someone from your Watched Drivers list in the Session. 
– – A Sessions filter has been added which matches Sessions that are currently “Open” for Registration as well as if a Session is “Ready Soon”. Additionally, Practice, Qualifier and Race Sessions can be filtered individually. 
– – For Table View, reduced the number of columns for improved legibility. 
– – For Table View, the column formerly known as “Promo” has been renamed “MPR” for clarity. 

iRacing BETA Interface – User-Created Races 

– The retrieval of Session data has been optimized, to get you the data you need faster and more efficiently. 

– Selecting individual cars or entire car classes, results in a more consistent interface. 

– For creating Hosted Sessions, “Fixed Setups” and “Car Classes” have been moved to the “Car Options” dropdown. 

– Car abbreviations now appear in the Hosted Session modal Entry List. 

– The Admin list is now alphabetized by driver. 

– Filtering enhancements: 
– – Individual car categories have been added to the Filter dropdown menu. 
– – “Owned” and “Unowned” have been added as Tags for cars. 

iRacing BETA Interface – Time of Day 

– Time of Day and Date/Time selection has been reworked to use sliders instead of the calendar. 
– – Time carry over has been removed in favor of simply not adding a time offset to the Session you are configuring. 
– – The estimated start time of a Session with zero offset is displayed for reference purposes. Moving the slider past zero will recalculate the date based on the starting time and the offset that you choose. 
– – Moving the slider bar will increase the offset of that Session and the starting time displayed will change based on the offset. 
– – When the offset carries over into the next day, the date will be displayed for reference. 

– Date formatting has been changed to be more internationally friendly. 

iRacing BETA Interface – Fixed Issues 

– Fixed an issue where Starred items would require a page refresh to be visible. 

– Fixed an issue in Current Series and User-Created Races where the team label would highlight a team for which the user did not belong. 

– Fixed an issue in the Open Practice tab where clicking the left “Register” button in a register dropdown menu registers the user as a Spectator instead of a Driver. 

– Fixed an issue where clicking the Active Connections button would cause the iRacing BETA Interface to error out. 

– Fixed an issue when selecting a track, sometimes only the first track config would be displayed as a choice. 

– Fixed an issue where opening a Hosted Session modal, joining a League Session, or launching a Test Drive could cause the application to error, and/or enter an unstable mode. 

iRacing Membersite – General 

– As of this 2019 Season 2 deployment, iRacing no longer officially supports the Internet Explorer web browser. 
– – For some web browser alternatives and more information on what this means, check out this post: 
– – http://members.iracing.com/jforum/posts/list/0/3639224.page#11436534 

iRacing Membersite – League Seasons 

– League Season Driver and League Team Points standings can now be viewed as Overall (All Car Classes/All Cars), by Car Class, by Car, or by Car In Class. 

– League Seasons can now be configured to drop races by specifying the number of races to count toward the standings. This can be set when creating or editing a season and a points system is selected. 
– – Races are dropped for an individual when the number they have participated in surpasses the number to count toward the standings. 
– – Races are ordered by the total points after adjustments with the highest scoring races being kept. Only adjustments made from the race results screen apply when determining if the race is to be dropped or kept. 

– League Seasons can now be edited to change the season name, the points system, or number of races to count. Edit a League Season by selecting it and then using the new “Edit” button in the header. 
– – Changes to the points system apply only to Sessions run AFTER the change was made. 
– – If the points system is changed from “Custom” to something else, the original Custom points schedule will be deleted. 

– League Season points adjustments can now only be made from the standings when viewing the overall (All Car Classes/All Cars) to be more clear that these adjustments count toward all of the standings, not only for a specific car class or car. 

– League Season points adjustments made from the standings view are added in after races have been dropped for an individual. 

– A new points system has been added as an option for League Seasons called “Dirt” which corresponds to USAC’s 2019 feature event points for non-Silver Crown races, as found in section 5.9 B. here: http://www.usacracing.com/assets/files/rules/2019/2019_part_4_Points.pdf 

iRacing Membersite – League Heat Race Results 
– For League Heat Races, the “Points” column now reflects the points earned in that segment. 

– A new column called “Agg Points” has been added to the League Heat Race Results and reflects the total number of points earned from the first segment to the current segment. 

iRacing Membersite – Spectator Sessions 
– When Series Sessions that are available for spectating continue into the following race week, they will now be listed separately from the current race week sessions. Each list will be titled by the correct track name for the race week. 

– Series Spectator Sessions are now first listed in order by license class (Rookie to Pro), then listed alphabetically within a license class. 

– Hosted and League Spectator Sessions are now ordered by Session Name. 

– Improved the performance of loading Spectator Sessions. 

iRacing Downloader 
– After applying the 2019 Season 2 update, the iRacing Downloader will now use IPv6 for its downloads if you have enabled iRacing to use this protocol, and you actually have IPv6 available. If a download attempt via IPv6 fails to connect, the downloader will retry using IPv4. If the download then succeeds using IPv4, the rest of your current download call will use IPv4. 

Engine Model 
– An engine cylinder compression torque model has been added to iRacing. 
– – At low RPMs (below idle rpm), as the engine rotates it causes cycles of positive and negative torque to be generated as the individual pistons are being compressed then released. The amount of torque generated depends on the engine configuration parameters, such as compression ratio and number of cylinders. This allows the motor to stall out properly, and allows it to get “stuck” between cylinder compression torque peaks and not roll away if the car is in gear without the clutch being pressed. This also produces a jerky motion if the vehicle is rolling at very low rpm. 
– – – The Anti-Stall Aid should be disabled in order to notice this in action, otherwise you will struggle to get the engine to go below idle. 

– The Driving Shift Aid has been updated. 
– – What was previously the “None” option was actually not none; it always left the Anti-Stall Clutch Aid on for you. With the updated engine stalling, we can finally let you turn the Anti-Stall Aid all the way off. Now, the “None” option really means no clutch aid at all. The “Anti-Stall Clutch” is now it’s own option. If you had “None” selected previously, you will now have the “Anti-Stall Clutch” selected to maintain the same level of behavior you had before. 
– – If you choose “None,” it is very easy to stall the motor if you do not press the clutch in at the right moments. Watch out if you are in a car without a starter motor! 
– – You will probably also want to turn the Auto-Starter Aid OFF and start the motor yourself. 
– – When setting up a custom event, the Hardcore Level dropdown has a new entry for “Disallow all driving aids” that forces the Shift Aid to None. 

– The engine startup sequence has been updated. 
– – All cars now have engine ignition and starter noises. 
– – The ignition/starter sequence remains a work in progress, and will be updated over time. Many cars will use a default sequence and share a generic set of sounds. 
– – Cars with unique ignition/starter sounds are as follows: 
– – – Audi Quattro GTO 
– – – Audi R8 LMS GT3 
– – – BMW M8 GTE 
– – – BMW Z4 GT3 
– – – Chevrolet Corvette C6.R GT1 
– – – Chevrolet Corvette C7 Daytona Prototype 
– – – Cadillac CTS-V Racecar 
– – – Dallara DW12 
– – – Dallara F3 
– – – Dallara IR18 
– – – Ferrari 488 GT3 
– – – Ferrari 488 GTE 
– – – Ford Falcon FG V8 
– – – Ford GT 
– – – Formula Renault 2.0 
– – – Formula Renault 3.5 
– – – Holden Commodore VF V8 
– – – Indycar Dallara – 2011 
– – – McLaren MP4-30 
– – – Pro Mazda 
– – – Skip Barber Formula 2000 
– – – V8 Supercar Ford Falcon – 2012 
– – – Williams-Toyota FW31 

– Certain cars require the clutch pedal to be pressed (if the anti-stall clutch is not enabled) before the starter will operate: 
– – Ford Mustang FR500S 
– – Global Mazda MX-5 Cup 
– – Mazda MX-5 Cup – 2015 
– – Mazda MX-5 Roadster – 2015 
– – Pontiac Solstice 

– Certain cars have anti-stall clutch behavior built in to them, so even if you turn the Shift Aid to None, they will still have anti-stall. 
– – Audi R18 
– – Dallara DW12 
– – Dallara IR18 
– – McLaren MP4-30 
– – Porsche 911 GT3 Cup Car (991) 
– – Porsche 919 Hybrid 
– – Williams-Toyota FW31 

– Direct drive cars with Shift Aid set to None will still use Anti-Stall Clutch Aid when in the pit stall, or in a starting grid location to allow you to start the car up and get rolling – at which time the Anti-Stall Aid is disabled, so you can stall the car if you spin or stop. 

– The auto-starter has been updated. 
– – When getting in a car, the auto-starter will wait about half a second before trying to start the car, instead of the instant you hit the Drive button. If you have stalled the car on track, the auto-starter waits 2 seconds (while stopped, in Neutral, or pressing the clutch) before trying to start the car. Pressing the throttle makes the auto-starter fire more quickly. 

Tire Model 
– The new version 7 (V7) tire model has been introduced on the Skip Barber Formula 2000. 
– – This model has significant improvements to both rubber compound modeling and tire carcass dynamics modeling, and the feedback has been very positive for the few vehicles we have been testing it on. Only the RT2000 has undergone enough testing to release with this build, but we hope to put this tire model on every vehicle soon

– The allowable cold pressure range has been opened up to allow pressures that are, frankly, too low (14 psi) all the way up to too high (45 psi), but we feel it is important to allow you to push the boundaries so we can better find out if the tire is behaving reasonably. Running at too low a pressure can give you a very evil car. High speed corners and low tire pressures do not work well together. Which tire pressure is optimal will vary from track to track, and sometimes you may find compromising one part of a track is worth extra speed in other parts of that track. Also remember that average lap time is often more important than best lap time, so don’t forget to average in extra time caused by spins! In other words, if you’re having trouble racing on low pressures, try raising them. 

League Racing 
– League Season Heat Racing events can now earn Season points. 
– – The Feature Race is allocated points based on the Season’s selected points system. 
– – Qualifying, Heats, and Consolation Races are only allocated points if they are configured to do so and the points system is not “None”. 
– – Points schedules and rules for Qualifying, Heats, and Consolation Races are based on USAC’s 2019 points schedules for non-Silver Crown races, as found in section 5.9 B. here: http://www.usacracing.com/assets/files/rules/2019/2019_part_4_Points.pdf 
– – – Qualifying allocates points to the first six positions, 6 points for first, and decreasing by 1 for each subsequent position. 
– – – Heats allocate points to the first eight positions, 8 points for first, and decreasing by 1 for each subsequent position. However, if Consolation Races are configured to receive points, then positions 5 through 8 only receive their points if they advanced directly to the Feature. 
– – – Consolation Races allocate points to the first eight positions, 4 points for first and decreasing by 1 for each subsequent position with 4th through 8th receiving 1 point. However, participants earning Heat Race points will not also receive Consolation Race points. 
– – – Stacked Consolation Races only allocate points for the final Consolation Race. Non-Stacked Consolation Race allocate points to each Consolation Race. 
– – – – Custom points will be supported in a later release. 

Heat Racing 
– The method in which drivers are appended to the Feature Race’s starting grid when there is more than one non-stacked Consolation Race has been updated. 
– – Previously, the specified number of drivers that advanced from a Consolation Race were appended to the Feature starting grid from the results of the first Consolation Race, then that number from the results of the second Consolation Race were added, etc.. Now, the winner of the first Consolation Race is added to the Feature grid, then the winner of the second Consolation Race is added, etc., followed by the 2nd place finisher of the first Consolation Race, then the 2nd place finisher of the second Consolation Race, etc., until the specified number of drivers have been taken from all of the Consolation Races. 

Dynamic Track 
– The system for calculating track temperature as reported to the user in the Info tab and telemetry has been improved. 

Dynamic Sky 
– Fixed an issue where Dynamic Weather mode would sometimes use the default cloud cover. 

Dirt Racing 
– Reduction to tire grip on dirt surfaces as the hardpan is approached has been amplified. 

Pit Stops 
– Rule changes for GTE pit stops have been implemented. 
– – Cars must now re-fuel first and may only change tires once re-fueling is complete. This takes into account the real-life WEC rules for the 2019/20 season. 

Rendering 
– Fixed an issue where teammates could not see the steering wheel rotate. 

High-Dynamic Range (HDR) 
– This release includes a preliminary version of High Dynamic-Range (HDR) rendering. When it is enabled the Simulator uses HDR render targets for items such as mirrors, environment maps, main render targets, and even HDR display back buffers. Previously, very bright pixels would be clamped to “fit” into Standard Dynamic Range (SDR) formats. This clamping causes important information about the actual brightness of bright pixels to be lost and to be treated as less bright than they should be treated. HDR rendering allows the bright pixels to be rendered without loss of information, and used during many internal rendering steps, limiting the loss of brightness to only the final step of converting to the display. HDR rendering drastically improves the quality of rendering, and also provides for additional future effects (this is a very early version!). And, when coupled with an HDR display, it allows for an expanded color gamut and extremely bright sun and solar reflections to actually be displayed at higher intensity than the rest of the scene on the display. HDR does not require an HDR display to provide most of the visual benefits because many of the benefits occur before the conversion to the display, but HDR displays benefit the most. 

– Support has been added for HDR displays, such as HDR10 televisions and monitors. The Simulator can now be configured to output HDR formats to an HDR display via an HDR10 frame buffer (10-bits per color channel instead of 8), or an HDR16F frame buffer (16-bit floats per color channel). When using HDR16F, the Simulator renders a special expanded color space (BT. 2020) using a special gamma (ST.2084). When rendering in HDR10 mode the Simulator just outputs the smaller color space BT.709 (HDTV color). However, Windows or the device driver may do conversions in either case, so you likely want to try both. When used in conjunction with HDR rendering, very bright sun and solar reflections can be displayed on screen, and the expanded color space looks incredible. You almost certainly need to be in full-screen modes when using these formats, especially HDR16F. If the Simulator leaves full screen, the colors may look blown out, and you may need to press Alt+Enter to get back into full-screen. 

– To enable HDR rendering without an HDR display, all you need to do is check the “HDR rendering” checkbox on the Graphics Options screen, and restart the Simulator for it to take effect. When HDR rendering is checked, bloom is also checked, and cannot/should not be unchecked for best results. Enabling this option will use more video memory to store the extra large image formats, but higher end cards should have plenty of memory for this. 

– To enable an HDR display, you will need to run the iRacing graphics auto-config and select an HDR10 or HDR16F mode from the resolution dialog, this will automatically force on HDR rendering and bloom. Try both HDR modes and select whichever works best for you. HDR10 uses slightly less memory, but HDR16F looks best in many cases due to the expanded color space. If the graphics auto-config does not present either of those modes, then you first need to setup your HDR display properly in Windows 10. HDR displays only work with Windows 10, and only when connected with higher-end display port 1.4 or HDMI 2.0 connections. And, in the Windows 10 display settings, the display first needs to be setup to be HDR. See the Windows 10 HDR settings in the Windows Settings -> Display Settings. If you cannot get Windows to first recognize the display as HDR and allow you to toggle it into HDR mode for gaming, you will be unable to get the Simulator to provide the HDR modes via DX11. Please note, you may need to also alter a setting inside the HDR display’s menus to enable HDR mode on the desired input, this is very common, before Windows will detect it as HDR capable. HDR display modes will not work on very old versions of Windows 10, and will not work at all on Windows 7. 

Visual Effects 
– Photographer spectators have been spotted using flash photography in the stands, and around the track! 
– – These spectators will light-up their flashbulbs throughout a session, especially when there’s some serious action going on! 

– Visual effects generated via PopcornFX should now better obey a users’ selected minimum detail level. 

Virtual Reality 
– A form of nVidia’s simultaneous multi-projection, named Single Pass Stereo (SPS), has been added to help optimize VR rendering. SPS allows the Simulator to render the scene for one eye, and then GPU, via shaders and SPS, create the image for the other eye, without the Simulator needing to submit the entire scene a second time. This reduces the CPU load of the rendering thread and increases the frame rate, especially for the largest and most complex scenes when the frame rate would be lowest. 
– – SPS requires a supporting nVidia GPU with a newer device driver installed. GTX1000 and GTX2000 series GPUs, with device drivers after v390 support it. The option is called “SPS” on the Graphics Options screen, and it will be enabled by default if your device driver reports that your GPU supports it. If the SPS option is disabled in the Graphics Options screen, and you have a supported GPU, try a newer device driver. 

– Fixed an issue when using VR where the mouse cursor could get stuck on a “curved screen mode” while using the iRacing BETA Interface, even when not on a curved screen. 

Audio 
– Ignition and starter sequences remain a work-in-progress, and will be updated over time. 
– – Currently, many cars will use a default audio sequence and will share a generic set of sounds. 
– – Cars with unique ignition and starter sounds are as follows: 
– – – Audi Quattro GTO 
– – – Audi R8 LMS GT3 
– – – BMW M8 GTE 
– – – BMW Z4 GT3 
– – – Cadillac CTS-V Racecar 
– – – Chevrolet Corvette C6.R GT1 
– – – Chevrolet Corvette C7 Daytona Prototype 
– – – Dallara DW12 
– – – Dallara F3 
– – – Dallara IR18 
– – – Ferrari 488 GT3 
– – – Ferrari 488 GTE 
– – – Ford GT 
– – – Ford Falcon FG V8 
– – – Formula Renault 2.0 
– – – Formula Renault 3.5 
– – – Holden Commodore VF V8 
– – – Indycar Dallara – 2011 
– – – McLaren MP4-30 
– – – Pro Mazda 
– – – Skip Barber Formula 2000 
– – – Williams-Toyota FW31 

– All cars have had their engine load sounds modified to be more sensitive to subtle changes in throttle levels. 

– All gear shift volumes for all cars have been adjusted. 

Driver 
– Additional detailing has been added to the driver’s gloves. 

Animated Pit Crew 
– The animated pit crew will now look directly at your car as it approaches and leaves. 

– The animated Indycar Pit Crew has been training all season, and is now 10% faster! 

– The reflectivity of skin-tones in light has been reduced slightly. 

– The air wrench hose movements have been smoothed a bit, and should appear less jaggy. 

Pace Car 
– A new pace car model, Porsche 911 GT3 Cup Car (991), has been added to the iRacing service! 

– The default Road pace car is now the Porsche 911 GT3 Cup Car (991). 

Replay 
– When playing through a Session change, the system will look forward for data to prepare the replay world for the new session. 
– – This fixes an issue on Session transitions where the track in replays could appear to have a stripe-pattern effect. This was being caused by data from the previous Session being used to create the track state, only then to have it overwritten in chunks with the new data. 

Cameras
– While using the camera tool, blimp velocity may now be a negative number, so it can rotate in both directions. 

Admin Commands 
– A new Admin Command, “!trackstate”, has been added. 
– – This command allows an Admin to view and change the track state of the NEXT Session. 
– – – This is intended especially for dirt racing, to allow Admins to make on-the-fly changes to the track (like simulating some re-prep before the feature for example). 
– – – – You can type “!trackstate” with no arguments to see the track state for the next session. You can adjust it by putting a number as an argument, like “!trackstate 30” (“!trackstate 30%” is safe and will work too). If you go with say “!trackstate -1” or any negative number less than that, you’ll get carry over in the next session (0 means 0% usage). 

Telemetry 
– A new telemetry variable, “PitsOpen” has been added. This variable is true if you are currently able to receive service in your pit. 

– A new telemetry variable, “PlayerCarInPitStall” has been added. This variable is true if you are stopped in your stall and parked cleanly so that you can receive service. 

Peripherals 
– The Fanatec API has been updated to the latest version. 

EasyAntiCheat 
– The iRacing software has been updated with the latest EasyAntiCheat libraries.

In iRacing, you will see the M8 in the multiclass IMSA Series as well as the iRacing Le Mans and iRacing Le Mans Endurance series. A front engine car, the BMW has already earned a reputation for being tough to pass due to its performance and size. iRacers will have the opportunity to race the M8 wheel to wheel against the Porsche RSR, Ford GT, and Ferrari 488 and find out for themselves which of the GTE cars will reign supreme.

February 7th, Season 1 Patch 4

This release includes some fixes and updates for 2019 Season 1. 

CHANGE LOGS: 

Membersite

Connectivity 

– Fixed a bug that could cause cars to temporarily disappear if the Race Server hit a particular error condition. 

– Fixed a bug that could cause the set of cars that the Race server sends to a user to not necessarily be the cars that are closest. 
– – This could occur in two different situations: while a spectator in a Session, or if there was a network hiccup that caused a user to briefly “wink-out” inside the Race Server (the kind of error that could lead to laps being marked “discontinuity”). 

Race Control 

– Fixed an issue where if a gained time checkpoint gets triggered in an area at or inside a very sharp corner of track geometry, the car could appear to already be before the checkpoint and cause the rule to immediately think the car had already yielded enough time and cancel the gained time tracking before it even started. 

Heat Racing 

– Fixed a bug in the formation of the Feature Race starting grid that could improperly restrict the number of cars that make it into the Feature. 

– Fixed an issue where the results of drivers who would not run in the Feature Race where included in the pre-Feature Warmup Session results. 

Pit Stops 

– Improvements have been made to the wing and clip replacement algorithms so that now the repair timer is aware of them. It will report their progress as part of the required repairs countdown timer. This should help clarify when a car is still actively receiving repairs. 
– – This change effects the following vehicles: 
– – – Chevrolet Corvette C7 Daytona Prototype = Nose replacement. Work only begins after the car comes off jacks. 
– – – Indycar Dallara – 2011 = Front wing replacement. Work only begins after coming off jacks. 
– – – Dallara DW12 = Front and rear wing replacements. Work only begins after coming off jacks.

– – – Dallara IR18 = Front and rear wing replacements. Work only begins after coming off jacks. 
– – – Formula Renault 2.0 = Front and rear wing replacements. Front wing work begins while on jacks, and rear wing work begins only after coming off jacks. 
– – – Formula Renault 3.5 = Front and rear wing replacements. Front wing work begins while on jacks, and rear wing work begins only after coming off jacks. 
– – – McLaren MP4-30 = Front wing replacement. Work only progresses while on jacks. 
– – – Williams-Toyota FW31 = Front wing replacement. Work only progresses while on jacks. 

Controls

CHANGE LOGS: 

Tires

– – Located at the Tulsa Expo Center in Oklahoma, racers from around the country across multiple disciplines come together to bear witness to what has been dubbed the ‘Super Bowl of Midget Racing’. The Chili Bowl Midget Nationals is a prestigious dirt racing event that has seen the likes of Tony Stewart, Kasey Kahne, Christopher Bell, Kyle Larson, Rico Abreu, and the Swindell family fill the grids. The inaugural Chili Bowl was organized by Lanny Edwards and partner Emmett Hahn. It was named after a local company who sponsored the first event. The race has been hosted at the Tulsa Expo Center since it was founded in 1987. The inaugural 1987 event consisted of 52 midgets competing in the 2-day event. The event now consists of four days of qualifiers for the Saturday night A-main event. The Chili Bowl’s key ingredient is the clay which once covered the adjacent fairgrounds. Without sun or wind to harm it, the indoor garden (roughly a quarter-mile circle) is heavily saturated so that the boldest dirt track artists of our time can truly shine. It accommodates over two hundred race rigs, bleachers for thousands of people, and an ever-growing trade show. To stroll the aisles of Tulsa’s QuikTrip Center, the home of The Golden Driller, is to rub shoulders with champions from across America. 

– Grab yourself a helping of the fabled indoor dirt oval from the iRacing Store! 

Circuit des 24 Heures du Mans

– – – Reset will clear all selected content and settings. 
– – – Last Settings will load the last successfully hosted session information to all fields. 

– Active Sessions are now visible for User-Created Races. A user may Spectate, Spot, Crew, or start a Time Trial any Session that is actively running. 
– – Viewing Active Sessions can be toggled on and off. Click on the “Show Running Sessions” toggle next to the view buttons. 

– Test Drive is now available as an option from any Session. 
– – A Test Drive button will now always be displayed for all Sessions, which will launch a Test Drive session using the information from the session you are viewing. This includes all Official Races and all User-Created Races. 

– Season and Series ID is now visible in the interface. 
– – Click on a Series, then click on “Series Info” to view this information. 

– The track list will now by default only display the list of tracks, instead of a list of all tracks and all of their configurations listed out. Once a track is selected, you may select an individual config. 
– – An option has been added so that you may toggle between having the track list display the list of tracks or having the track list show all tracks and all of their configurations listed out. 

– The status bar at the top of the screen now features a tinted background for ease of legibility and use when the Interface is scrolled down. 

– The iRacing Paint Shop within the iRacing BETA Interface should now be better at remembering when changes are made to cars. 

– The iRacing BETA Interface now has an active display of all authenticated connections for your account, with verbose information about the connections, and the ability to manually disconnect remote, active connections. 

– The settings panel now has a button to sign out your authenticated connection, plus all other (in)active connections, whether remember me has been selected or not. 

– Page content will now fill more of the screen when the interface is scaled to 150% or less. 
– – This should improve the display of the iRacing BETA Interface on 27″ monitors. 

– Fixed an issue where dropdown menus could appear under other content. 

– Fixed issues where “invalid date” would display, or the year listed would incorrectly be 1969. 

– Fixed an issue where the user was not returned to the last page they were on after exiting a Session. 

– Fixed an issue where switching to/from table view and grid view, the Interface was not remembering which view a user was using the next time they returned to that page. 

– Fixed an issue where the Interface was not remembering whenever the user chose to order content a certain way after navigating away and returning. 

– Numerous other stability fixes; the iRacing BETA Interface should run smoother than ever! 

iRacing Membersite 

– The iRacing Membersite has been updated to allow for editing Sessions created via the iRacing BETA Interface. However, the user will be unable to edit settings that are only available when creating a Session through the iRacing BETA Interface. 

– Various Day/Night & Time of Day information has been added to the Membersite: 
– – Sunrise and sunset times will be displayed for all sessions. 
– – Simulated start time will be displayed in the Session Info for Official and Hosted Sessions, and in the Race Results. 

– A new and improved banner has been added to the top of the Membersite to launch the iRacing BETA Interface! 

– Fixed an issue in the shopping cart where the hyperlink of a track added to your shopping cart from the iRacing BETA Interface was not linking to the proper track. 

Series Special Event Races 

– We have added a new feature which allows us to schedule Special Event Races for a Series within the normal season schedule. Each special event is a stand-alone racing event, and entry is based on championship points within the series. Championship Points awarded from such an event are not integrated back into the Series. 
– – We could, for example, schedule a single split race, that would be populated by drivers with the top N in Championship Points, either for a given race week, or the overall season. Or, we could have a “Week 12 Pro Race” automatically built into any given Series for the top 40 drivers, based on Championship Points in that Series during the Season, who show up for the given race time slot. The top 40 who show up based on season points would race. 
– – Championship Points earned from Special Event Races are stand-alone, and are not part of the regular Series standings. 
– – We will likely be demonstrating this feature during Week 13, and it may even include some prizes, so, stay tuned! 

Dynamic Track 

– Initialization of a track on the client is now influenced by how many laps have been driven (including carry-over between sessions). This will enable clients to enter a session without causing a dramatic change in the track appearance as the server updates come in. 

– The maintenance of track temperatures between sessions, such as the heat added from cars during a Qualify session, will now carry-over and dissipate through the passage of simulated time between the end of one session and the start of the next. 
– – Previously it was assumed that enough time existed between sessions for the track to return to its equilibrium state at the start of each session. 
– – You may directly influence this through the new Day/Night & Time of Day settings. For example, setting your events to run consecutively will create more vehicle-generated heat buildup throughout your event than having each session start four hours after each other. 

Day/Night & Time of Day 

– The Simulator now generates dynamic skies that change as time passes. The sun’s motion in the sky is accurate for the selected event location, date, and time. As the sun and cloud cover move, the lighting in the simulated environment changes to match the sky. 
– – The generated sky will change as time elapses for all Sessions of all types, except for old Replays, Time Trials, and Time Attack Sessions, where conditions are frozen by design. 

– The shadows cast by static objects, such as buildings, trees, and grandstands, now move over time to match the sun’s angle. 
– – These shadows also influence the dynamic track’s temperature where they are cast over time. 

– Regular Season and Hosted events now specify a specific starting date and time for the event. 
– – A user may only select a day of the year for the start of an event that is within the normal range of dates during which the real-world track would be open for on-track activities. 
– – – The default starting date for a Hosted session is a reasonable date in late Spring. 
– – Each Session within a Regular Season or Hosted event (Practice, Qualify, Race, Heat, etc.) also has a specific start time within a 36 hour window relative to the starting date and time of the event. For example, you may create a Hosted Session that features an early morning Practice, followed by a twilight Qualify, followed by a sunrise Race. The default option is to run each session consecutively, so that as soon as one finishes, the next one will begin in real-time. 
– – For Heat Racing Sessions, a user may only specify the specific start times for the first Session within each block of sessions. For example, you can specify the start time for the first Heat race, but not for each subsequent Heat race. A user may also specify the start time for the first Consolation race, but not for each subsequent Consolation race. 

– When selecting the date and time for an event, the local time zone for the selected track is used. 
– – Daylight Saving Time adjustments are taken into account when specifying the event start date and time. However, if a session runs through a time change point, the in-session date and time clock will not adjust for this. 

– Event starting times may still be specified using generic presets: Sunrise, Morning, Afternoon, Late Afternoon, Sunset, and Night; or a user may specify a precise time at the track, such as 3:30pm. 
– – When using the generic presets, the event start time positions the sun at a specific altitude above the horizon to match the generic term. 
– – – Sunrise sets the start time such that the sun begins about 0 degrees above the eastern horizon. 
– – – Morning sets the start time such that the sun begins about 20 degrees above the eastern horizon. 
– – – Afternoon sets the start time such that the sun begins about 58 degrees above the western horizon. 
– – – Late Afternoon sets the start time such that the sun begins about 15 degrees above the western horizon. 
– – – Sunset sets the start time such that the sun begins about 0 degrees below the western horizon. 
– – – Night sets the start time such that the sun begins about 20 degrees below the western horizon. 

– Tracks that have night lighting (ie: any of the iRacing tracks for which a user has been able to select a “Night” event at before) will switch to “Night Mode” during the sunset/twilight phase, and the stadium lights will switch on. These lights will turn off during sunrise. 
– – Tracks without night lighting will still function using the Day/Night & Time of Day system, however they will get darker and darker until they are nearly pitch black. We do not recommend driving cars without headlights at these tracks past sunset. 
– – – As a special bonus, with this 2019 Season 1 Release, Circuit des 24 Heures du Mans has been updated to feature Night Mode! 

– The speed at which the sun moves across the sky may be altered. 
– – For example, an entire simulated day can occur within a 3 hour session. This “accelerated time” only affects the sun itself and how it changes the temperature of the day or night. Weather, cloud cover, etc. are not effected by the accelerated time. 
– – When creating a Session, you may specify 1x, 2x, 4x, or 8x speed for the sun. Please note, the track surface temperatures may not keep up as accurately with a highly accelerated sun as they would at normal speed. 

– The Simulation will display the simulated day of the week and wall-clock time in the F1 Black Box, and it will display the simulated date and time on the Replay screen. 
– – While in a session where the sun’s motion is sped up, the wall-clock date/time values will advance at the appropriate rate, and will include the appropriate “2x”, “4x”, or “8x” sun-motion-factor indicator. 
– – In Time Trial and Time Attack Sessions, since the sun position is fixed, these simulation-world date/time values are also fixed, and will include a “0x” sun-motion-factor indicator. 

– Clouds now cast shadows, and these shadows update dynamically as the clouds and the sun move as time passes. Each cloud shadow effects the dynamic track surface temperatures. 
– – When using Specified Weather for an event, the event will start at the specified temperature, but may drift up or down a few degrees depending on the time of day and the duration of the session. 
– – Please note, when building fixed racing setups, expect at least some track and air temperature variance during sessions. 

– Temperature, relative humidity, wind speed, and other weather values will change as time elapses during a session. 
– – Currently, these changes are very minimal, and using Generated Weather will allow for slightly more variation during a Session than using Specified Weather. A new weather system is currently in development which will allow the sky conditions to change during the session (ie: clear to overcast, etc,) and will result in far more dynamic weather throughout an event. 

– New “Sky Detail” Graphics Options have been added! 
– – These settings control how many frames are used to update the sky. Low Detail spreads the work out over more frames, so the sky updates may appear jumpy, but the frame rate will be higher. High Detail does more work per frame so the updates are more frequent, but this can adversely affect frame rate. Medium Detail is an average compromise. 

– You must use the iRacing BETA Interface in order to access all of the Day/Night & Time of Day settings that are now available. However, the system will still operate correctly in Sessions created and joined via the classic Membersite. 

– Old saved Replays will now load up with a generated sky instead of the static skyboxes of the past. The sun position and sky conditions will attempt to match the conditions of the original replay to the best of their ability, within reason. The sky will then remain fixed while the Replay runs. 

Driving Aids 

– The Auto-Start Aid is now optional, you can turn it off if you want to manually start your engine when you get into the car. This will be forced to OFF if you map your ignition to an ON/OFF toggle switch. 

– The Auto-Start Aid and Auto-Clean Visor Aid are now allowed when using Touch/Tilt Driving. 

Rallycross 

– Track-config specific setups have been added to a variety of the Rallycross vehicles. 

Hybrid Power Units 

– The PID auto-deployment system now re-calculates the control variable (EOS % offset) multiple times per lap. 

– Adjusted the hybrid system to include the manual deployment offset that compensates for the requirement of a non-zero base value from the refline calculations. 

– Updated the refline calculations for hybrids that reduces placement of end-of-straight markers due to cornering drag. The system needs to see 6 consecutive segments with a drop in speed before it will place an EOS marker. 

– Additional updates to the auto-tuner. The aim with these changes is to achieve greater stability – slower to converge, but less variation once it gets there. 

– PID parameters changed for faster but more stable convergence to target battery charge %. Also, % end-of-straight speed multiplier capped at a maximum value of 1.1. 

– Updated the engine system to account for the Porsche 919 harvesting more energy than it may legally deploy at Le Mans. 

– Fixed a bug where the battery state of charge was not correctly being carried over between driver changes. 

Crowds 

– The crowd system has been rebuilt from the ground up to significantly improve both appearance and performance. In the previous system, crowd members would only be seen facing the camera directly from the front or directly from the rear. With this new system, crowd members now render from 360 degrees and face towards the racing action, rather than towards the viewer’s camera. 

– Each crowd member is rendered from a high fidelity 3D model to a texture with four times the amount of pixels than previously. This results in a crisp, high resolution appearance with accurate normal maps and lighting in the Simulator. The variety of crowd appearance has also increased, with over 33% more unique people than before. 

– Each crowd member is also now an instanced object, and each race fan takes advantage of this technology to reduce their memory usage and rendering time. 

Paint Kit 

– The texture size for all helmet patterns has been increased from 512×512 to 1024×1024. 

– Radical and SimSpeed sponsors have been updated. 

Options 

– All in-car controls not currently in use will no longer be displayed in the Options screen. 

– Some Options and Replay Options screen items have been rearranged and adjusted: 
– – A Sky/Cloud Detail setting has been added to the Options screen. 
– – The Virtual Mirror setting has been removed from the Replay Options screen. 
– – The Far Terrain and Tri-linear Filtering options have been removed from the Options and Replay Options screens; these options are still available for adjustment in the “.ini” file. 

Controls 

– Support has been added for mapping an ON/OFF switch to some toggle controls, that is a switch that remains ON or OFF rather than just a momentary toggle. 

– A checkbox has been added to the Option Screen to disable the Auto-Starter Aid that starts your car when you enter the driver’s seat. 
– – By default, this checkbox is OFF. 
– – The ignition will no longer fire when you trigger the starter, a driver must manually turn on the ignition if you want to run the starter. 
– – – The Default Ignition option is set to OFF if the Auto-Start is disabled. 

– Support has been added for the new QAxis control type. This is a rotary knob that acts as a sequential series of buttons. If the knob has more positions then the states in the item we are attempting to control then each detent on the knob will be mapped 1:1 to the states. 
– – For example if the throttle map has 3 possible options, but your knob has 12 positions, then positions 1, 2, and 3 will adjust the throttle mapping, rather than forcing you to rotate the knob through its full range as you would with an analog knob. If there are more states then positions for the knob, then we will spread them out as best we can, skipping some intermediate states. 
– – Any hardware developer wanting to add a QAxis knob to there controller needs to ensure that the button defines are in sequential order. So a 4 position knob could use buttons 12, 13, 14, 15, but could not use buttons 12, 14, 13, 7. More details on this will be posted to the hardware forums. 
– – The Fanatec CSL Elite McLaren GT3 rim is currently the only rim that ships with support for QAxis rotary knobs, however new rims are expected to be released later this year. 

– A calibration wizard has been added to the in-car controls to simplify the process of setting them. 

– All F7/F8 black box widgets now have a corresponding map-able control. 

– Control calibration improvements have been made, including the enforcement of expected control type when calibrating. This will prevent users from mapping a button to an analog slot by accident. 

Admin Commands 

– Admins are now allowed to throw a Caution, even when the event has cautions set to “OFF”. 
– – For all intents and purposes, this option now means that when cautions are turned off for an event, iRacing Race Control does not throw Cautions, but an Admin may. 

Force Feedback 

– The force feedback setup screen has been reorganized to better support direct drive wheels. 
– – Force units have been rescaled so that linear and non-linear are using the same unit scale. 
– – Clicking on the Strength value will toggle between iRacing units and Newton meters. 
– – A new Wheel Force slider has been added. 
– – – Set this to the peak force of your wheel to help keep the auto function from overdriving your wheel. This also rescales the strength slider so you can not manually oversaturate the wheel on accident. This is only beneficial for users with wheels that are as strong or stronger than the force feedback we are getting from the physics (about 10 Nm or greater), so do not worry about setting it perfectly if you have a belt or gear drive wheel. 
– – “Dampen Oscillations” has been renamed “Reduce Force When Parked” to better reflect what this option does. Also, the default value for this setting has been reduced to 33% from 50%. 
– – The default endstops have been softened from 15 degrees to 45 degrees. 
– – A hard knee has been added that reduces forces above 80 Nm by 80% and clips forces above 120 Nm. 
– – – This should make running into a wall safer without completely destroying the signal. 
– – Mouse-over tooltip help has been added to all force feedback settings. 

– Helper text for racing wheel settings has been updated. 

Replay 

– A pair of settings have been added in the [Replay] section of the “app.ini” file to control how many seconds from the end of the tape Replay playback begins when exiting the car. One setting is for driver swap events, and the other is for non-team events. 

– The “FF to End” behavior has been optimized to reduce system load, and to maintain Live Mode viewing when a new session begins. 

Oculus Rift 

– Rift HMD 1.3.2 support has been migrated to Oculus SDK 1.26.0. 

EasyAnti Cheat 

– A new version of the EAC application has been integrated into iRacing.

Dallara F3 

– NEW CAR! 
– – The Dallara F3 is now available for purchase and use on the track! 
– – – The Dallara F3 car is raced in one of the most successful racing series in the world, Formula 3. It’s a development series for up and coming drivers in Europe, the United States, Asia and Australia and has seen many a high profile driver move to the top ranks of open wheel racing in Formula One and IndyCar. Raced in spec series, the F3 car was designed for young drivers to move their way up through the ranks of open wheel racing. Racing an F3 car is often the first venture into professional level racing for young amateurs. 
– – Purchase your Dallara F3 from the iRacing store, right here: http://members.iracing.com/membersite/member/CarDetail.do?carid=106

Formula Renault 2.0 

– Garage layout and notes have been updated. 

Formula Renault 3.5 

– NEW CAR! 
– – The Formula Renault 3.5 is now available for purchase and use on the track! 
– – – The (much) bigger brother of the Formula Renault 2.0, the FR3.5 is the perfect fit in the iRacing open wheel ladder system. The open cockpit, V8 powered cars, were traditionally a stepping stone for many drivers who were pursuing careers in Formula One. Featuring a spec chassis and spec motor, the cars allowed drivers to showcase their skills and hopefully get noticed by a Formula One team. The normally aspirated V8 motors produce 530 bhp and the large wings, both front and rear, provide large amounts of downforce and grip. Some say the FR3.5 sounds like a Formula One car should, or at least used to, before they moved to the turbo/hybrid power units. 
– – Purchase your Formula Renault 3.5 from the iRacing store, right here: http://members.iracing.com/membersite/member/CarDetail.do?carid=105

– (Rallycross Long) – Adjusted the levels of compact and loose dirt in the starting area, and fixed an issue with the 3rd place starting grid position. 

Charlotte Motor Speedway 

– NEW UPDATED TRACK! 
– – Charlotte Motor Speedway, a newly updated asphalt oval and road track, has been granted to all iRacing Members for FREE! 
– – This track currently features one track configuration: 
– – – Roval 
– – Additional track configurations are planned for release at a later date. 
– – The Charlotte Motor Speedway built a new infield road course, designed specifically for NASCAR competition, in 2018. It utilizes nearly all of the 1.5 mile oval as well as newly built infield portion, thus the name Roval (Road/Oval). The Roval configuration is a 17-turn, 2.28 mile track that challenges the best of drivers and team. Car setups are typically compromises, a car good on the oval may not be so good in the infield and vice versa so drivers and crew chiefs have to decide what matters most to them. Two chicanes, one on the back straight and one just before the start finish line, make for some exciting passing opportunities as competitors can attempt to out brake each other. The Charlotte Roval is a unique infield road course that has already proven to be an exciting venue since its NASCAR debut in 2018. 

– This track has been added to the default iRacing content, and is now FREE for all iRacing Members! 

Charlotte Motor Speedway – 2016 

– The track formerly known as Charlotte Motor Speedway has been renamed Charlotte Motor Speedway – 2016 to make room for the updated version of this real-world track location. 

Circuit des 24 Heures du Mans 

– Night lighting has been fully implemented at this track! 
– – Now, when this track is selected to run at Night, or the new Day/Night & Time of Day system transitions to or from night, all track lights, reflectors, and environment lighting will work correctly and seamlessly! 

Circuit of the Americas 

– Several terrain seams have been fixed. 

Indianapolis Motor Speedway 

– (IndyCar Oval) – Pit stall positions have been shifted slightly. 

Tsukuba Circuit 

– NEW TRACK! 
– – Tsukuba Circuit, a brand new asphalt road track, has been granted to all iRacing Members for FREE! 
– – This track currently features seven track configurations: 
– – – 1000 Full 
– – – 1000 Outer 
– – – 1000 Chicane 
– – – 1000 Reverse 
– – – 2000 Full 
– – – 2000 Moto 
– – – 2000 Short 
– – Tsukuba Circuit, located in Japan, was built in 1970 and is known for hosting sports car, open wheel and motorcycle races – and most notably Time Attack competitions. There are two main configurations, Course 1000 and Course 2000, with multiple variations of both. This makes the track a perfect fit for the iRacing base package as it can be used in multiple series without becoming repetitive. Course 2000 is just over 2 KM in length and features 14 turns. Course 1000 is approximately 1 KM and has 11 turns. While the two main configurations share the same facilities, they are completely independent of each other and don’t share any racing surface. The tracks proximity to Tokyo, Japan has made it extremely popular with local car tuners who compete in Time Attack competitions. Expect to see Tsukuba Circuit feature in both race series and time attack competitions on iRacing. 

– This track has been added to the default iRacing content, and is now FREE for all iRacing Members! 


November 1st, iRacing Maintenance Release Notes

This maintenance will affect all iRacing services, including all Race Server environments, the iRacing.com Membersite, and the iRacing BETA Interface. Members will be unable host or join sessions during the downtime, and any sessions in progress at the start of the downtime will be terminated. 

This maintenance period will be used to perform another round of crucial work on the US Race Server and iRacing data center relocation project. Our database will be switched over to our backup, already at the new location, and then re-deployed to the new infrastructure at the new location. If all goes well, we anticipate this is the final major outage remaining to complete this move. 

We anticipate this downtime to be completed within 6 hours, however, it may take additional time after the iRacing services are back online to stabilize the user experience. 

The Test Drive iRacing service is already online and available.


 

October 29th, iRacing Maintenance Release Notes

This maintenance period will be used to perform crucial work on the US Race Server and iRacing data center relocation project. Nearly all race infrastructure will be transitioned to a new data center. As part of this work, we’ll be decommissioning our current US Race Server farm and creating a new one. Most of this infrastructure is already in place at the new data center, but we’ll be adding some critical networking gear that will help us better control routing between members and this new server farm. We’ll also be doing database work to remap Sessions and Seasons to the new farm. This is a significant milestone for us.
