Official Webpage –

2024 Season 2 Patch 2 Changelog:



  • A new filter, “Rain Allowed,” is now available on both Official and Hosted Racing pages.
  • Fixed an issue where the wind speed values advertised in weather information are always displayed as kmph regardless of user preferences.

Test Drive

  • Fixed an issue where trying to launch a Test Drive populated directly from an Official Series that changes cars each week (Ringmeister and Draft Master) was not selecting the correct car.
  • The Test Drive button in iRacing Web now offers to launch iRacing instead of failing to launch Test Drive.

Official Racing

  • The Forecast graph now correctly displays the Session time bars in the graph.

Hosted Racing

  • The Hosted Races table now caches the selected filters, sorts, and page numbers for browsing Sessions and for viewing your own created Hosted Sessions. This allows you to pick up where you left off when returning to the page.

Create A Race

  • For Open Setups, Setups are now listed in alphabetical order.


  • Fixed an issue where the Spectate page did not properly indicate which tab the user was on in some situations.
  • The Spectate Hosted Races table now caches the selected filters, sorts, and page numbers for browsing Sessions. This allows you to pick up where you left off when returning to the page.
  • – – This functionality remains in development for the Official & League tabs of the Spectate page.

Results & Stats

  • Removed an erroneous cancel icon from the date range filters.


  • Fixed an issue where users who had a password that did not meet current standards were prevented from updating their password via the UI.


iRacing Installation

  • A checkbox has been added to “Launch iRacing” after completing a new installation. 


  • Some additional checks and controls have been put into place which immediately remove a vehicle from the world if its physics values appear to be ramping unrealistically fast, which could lead to causing a “zippy” event. These checks stop these abnormal physics events from reaching the Race Server and prevent it from crashing multiple players simultaneously.
  • – – With this security measure in place, a user that would have experienced a zippy event, perhaps getting launched to the moon, is instead dropped from the race server and a crash dump file is created. To other drivers, this user will appear to have disconnected. Since their physics information is prevented from reaching the Race Server, all other drivers in the Session are protected from it attempting to process unrealistic values, and the Race Server will continue to run normally.

iRacing Weather System

  • The maximum allowable rain rate in Official Fixed Setup Sessions is now capped at a rate that is heavy enough to strongly encourage drivers to shake up their driving, but not so strong as to be detrimental to the Fixed Setups racing experience.
  • The rendering process for creating and clearing windshield wiper rainlines has been updated.
  • Some raindrop textures have been updated.
  • Opponent car windshield effects have been updated. 
  • The aero spray effects coming from cars has been updated.
  • Improved the process for wind speed calculations for Forecast Weather Mode.
  • Fixed an issue where water heights were being overestimated on some racing lines. This data was being sent to the user and track systems. 
  • Fixed an issue where tire spray effects for cars more than 30 meters away were not drawing correctly from in-car cameras.
  • Fixed an issue where the wet tire spray would render sideways to the camera at night, when night shadows are enabled with triple screen MVP enabled.

AI Racing

  • AI Drivers are ready to race for the gold in the SRX!
  • AI Drivers are now ready for rain racing with both the Ford GT GT3 and the McLaren MP4-12C GT3!
  • AI Drivers are now better able to determine if they should use regular or rain tires before getting on track.


  • When loading into a Session where rain and/or wet racing could occur, a new warning message now appears to inform users if they do not have their Graphics Quality set high enough to render rain and wet effects properly.
  • Fixed a graphical bug that could cause a sliding shadow effect on objects when SSAO was enabled.
  • Some vehicle carbon fiber textures have been adjusted for improved shader processing.


  • Added spotter messages when gridding that tell you when half the field has gridded, and when five, two, and one cars remain to be gridded.
  • The spotter will now always countdown to your pit box if the countdown option is enabled, regardless of what Spotter Chattiness level you have selected.
  • The Lap Time and Pit Service Finished spotter messages no longer play if the Race is over.

Active Reset

  • Opening the Options Menu now invalidates any Active Reset save state.
  • – – This prevents changing settings like shift mode that can invalidate the car’s state.
  • Fixed an issue where the Active Reset sounds were not playing correctly.


  • Simagic Haptic Pedal Reactor support has been re-enabled.
  • For Simucube wheels using the new 360 Hz API, the [Force Feedback] “forceResetBeforeStartup” option is now disabled by default.
  • For Force Feedback, the automatic calibration will now take the track surface wetness into consideration and will slightly reduce the maximum forces for wetter sessions.
  • Fixed an issue with the new clutch launch control.
  • – – This system now properly resets after the end of a launch, rather than remaining active for 5 seconds. Also, a new switch to change the mode from a “press-and-release to launch” to a “press-and-hold to launch” has been added to the “app.ini” file; This is named [Force Feedback] clutchLaunchMode=0.


  • Reworked the “irsdk_PitCommand_TC” command to be zero-based rather than one-based.
