Use ProtonGE so the game plays the startup video stuff, otherwise only a colorful placeholder displays.
The game ran in 20-45 FPS on my hardware, barely ever crossing 30% of GPU utilization reported by Mangohud. It did feel a bit sluggish, but was perfectly playable. Enabling ProtonGE FSR only made the game blurry and oddly, halved performance. After some research I stumbled upon a thread with a fix
https://www.reddit.com/r/linux_gaming/comments/nqwkaq/proton_low_gpu_utilization/
It appeared to work, apparently the game is made in Unity and does not really like SMT, which is fixed by WINE_CPU_TOPOLOGY
launch option. In order to use it, learn about the number of cores/threads in your Ryzen CPU (can't speak for Intel). On my example, I have a 16/32, so after the equal sign I put number of cores (16) and after colon I list the 16 cores, but starting from 0 instead of 1, hence WINE_CPU_TOPOLOGY=16:0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15
For 8/16 Ryzen CPU use WINE_CPU_TOPOLOGY=8:0,1,2,3,4,5,6,7
and so on.
Enabling it pretents around 3-4 times performance boost
The game is perfectly playable without the fix, but the feeling of smoothness coming from framerates is quite unsatifsying, even if just a rather minor inconvenience (speaking as user of a 75Hz screen)
Game crashes infrequently on the Windows port as well, seems like it crashes less overall on Linux than Windows. Limit the framerate in the settings or with an external program since the intro videos will run the GPU at 100%.
Appeared to function perfectly. Was able to pick up a save from my PC and continue as normal. Default layout was great. Highly recommend.
Screen strobed from white to black rapidly when booting but otherwise function perfectly.
Issues with native. Runs flawlessly with proton.
The native version didn't work for me but with proton, it runs without problems.
