2023 Season 1 Patch 4 Changelog


Guided Tours

  • The bowtie icon has been replaced with an “i” icon. Farewell, Jeeves!


  • We have added an input box for a new League Season option: “No Drops on or After Week X”. This allows the user to specify that race weeks cannot be dropped after a given week number. This feature is only enabled if the number or drop weeks is not 0.

Results & Stats

  • The iRacing UI now allows for viewing Standings by All Cars, by Car Class, by Car, and by Car in Car Class.

Paint Shop

  • Slightly reduced overexposure for bright colors.



  • The SpeedTree self-shadow option is now disabled by default for all graphics performance classes. Previously, it had been enabled in all graphics performance classes, but it requires two extra renders of the trees and may have contributed to stuttering or a general performance hit.

  • Rub block shapes have been updated.

NASCAR Cup Series Next-Gen Ford Mustang

  • Texture mapping on the front fenders has been updated, which fixes issues with damage decals and camera draw distances.

NASCAR Truck Ford F150

  • Fixed an issue with duplicate contingency decals on the nose.


Los Angeles Memorial Coliseum

  • Starting grid positions have been moved away from the wall slightly.

Long Beach Street Racing Course

  • Adjusted the location of the short parade lap grid to give the rear of the field time to get rolling before the green flag is given.

Wild West

  • Fixed an issue where cars that missed the start would be released immediately and would come out of the pits way ahead of the pack. Now, Race Control properly holds these cars for about 20 seconds so they come out just behind the pack as expected.
