2023 Season 2 Patch 2 Release Notes [2023.03.20.02]

This Patch includes a variety of updates and fixes for the 2023 Season 2 Release.




Fixed an issue where cars would appear to fly above the track surface at Charlotte Motor Speedway - Rallycross when back-patching was not in effect.


A new graphics option, ZBuffer32Bits, has been added to the “rendererDX1.ini” file.

- - This option is enabled (set to 1) by default, and forces the Simulation to use a 32 bit depth buffer. This helps NVidia users who are seeing excessive z-fighting. This option uses double the video memory for the depth-stencil buffer (it will grow from 32-bits to 64-bits per pixel).

AI Racing

AI Drivers have improved their racing behavior with the Skip Barber Formula 2000 and should be less likely to slide and smoke. Both were bad for their health.

New Damage Model

With the systemic New Damage Model changes released with 2023 Season 2, many vehicles were in a place of unrealistically higher durability. This patch includes a variety of vehicle body panel adjustments that should generally weaken their strengths, and make the cars much more realistic. We continue to assess realism and balance for New Damage Model cars with the 2023 Season 2 changes, and additional updates to these or additional cars may be in future Patches. The vehicles affected by these changes include the following:

- - <Car Class> GT4 Cars

- - <Car Class> NASCAR Classic 1987 Cars

- - <Car Class> Touring Class Cars
