Game runs smooth, but after a few hours it stutters when moving the mouse, but ONLY when moving the mouse.
Game works fine with Proton GE 9.7. I did encounter a strange bug, which I believe to be an issue in Linux, where my frame timing will stutter horribly when I move my camera. This only happened after about 4 hours of playing though, so it's pretty darn stable for most of the play time. Restarting the game fixed the issue, but I didn't play for an additional 4 hours to test.

Crashes after entering the game world if using Proton 9 or lower
MANGOHUD=1 %command%

No Launch Options
When switching to Windowed Fullscreen, the game freezes but can be unfroze by alt tabbing.
Runs at 40+ FPS on low settings but I forgive it for being Early Access. Developer seems to love feedback.
Works out of the box for me.

mangohud PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 %command%
The game seems to have trouble retaining settings, but I don't expect that's specific to Linux
