Run the game as experimental. Change the texture pool to High as another user stated. Other user says you wont have a hard lock if you set to The texture Pool Ultra and have enough Ram (32GB+). I have 64GB of ram and still had the soft lock when the texture pool was to Ultra. Turning the Texture Pool back to high fixed that issue and seems to be the sweetspot. The game is very playable with these settings and runs great. I get about 95FPS @5120x1440p 240hz with pretty much zero stuttering and a small hang maybe once a race.

I am also playing the game using my racing wheel. Fanatec CSL Elite. This worked out of the box without any issues with FFB. I did have to go to the settings to put in my keybindings though which took about 5mins. The keybindings saved no problem when I reboot into the game. I do have my wheel setup to play AMS2 as far as drivers and stuff goes so that may be why it worked so well right away.

All in all this works great for me and my hardware and I am very happy. Racing games were the only thing keeping me from staying on my linux partition full time and with this working as well as AMS2, Dirt Rally 2, and RBR. I'm never going back to windows.

Fingers are crossed that this compatibility isnt ruined with some further update.
