I initially installed this hoping to have it just work, but it consistently crashed when trying to start the game. After messing around with it, I found that forcing the use of ProtonGE 8-30 will make it work after letting it sit there for about 15-20 minutes on the Steam Loading Screen while it did its thing. Subsequent starts of the game are normal.

As the interface is very Mouse driven, I then switched to the Gamepad with Mouse Trackpad configuration remapping the Start button to the ESC key. Using the X360Default Configuration Preset in the Controls menu enables everything to work as it should.

Using the OLED Deck, I was able to consistently hit 90fps with max Anisotropic Filtering, Anti-Aliasing Samples, World detail and Shadow Resolution in practice mode and 70+ fps in a race with 11 other cars on screen. Works in Game Mode and no need to Force 32-bit in the General Settings.

I have not tried with any DLC or Mods installed.
