Around the edges of character models and objects in the distance, there are very distracting artifacts, almost like a pixel mosaic filter. Since they don't affect the track or the cars, it's possible to play anyway, but they are always present. There is also occasionally a small but intense vibration across the whole screen, almost like camera shake but a very small amount going incredibly fast, which I'm sure isn't part of the game since it happens seemingly at random and I have camera shake turned off anyway.

My controller simply would not work... but only sometimes. Restart the game once or twice and it works again. Sometimes, it works first try.

The game struggles to reach 120 fps, most often floating around 105, sometimes dipping down as low as 70, and has frequent stutters that drop below 50. Setting the graphics settings to ultra low allows the game to reach 120 more often and to dip less often, but the stuttering does not improve. Rarely, it has a stutter so heavy that it seems to affect the physics and AI in the game. Oddly, vsync has almost no effect on the game, but it does have an effect on OBS if I try recording the game, dropping the OBS capture to 30 fps whenever my actual framerate dips below my refresh rate, or half of it if vsync interval is set to 2.

The game does not launch without disabling simultaneous multithreading in the BIOS. With SMT enabled, it gives error code R6025. I'm assuming this only happens to people with more than an 8c/16t CPU.
