"PROTON_USE_WINED3D=1 %command%"
Unnatural blinking of light in some scenes.
The game freezes in the ending scene. After resuming, it freezes when reaching for the key to the cell. This may be considered quite a game-breaking bug as it effectively made me to watch outro on YT.
Game not loading/Crashes
I cant get further than 1 minute after clicking "play" in steam before the game crashes. Thus i cannot give any real information. On Pop!_OS.
When using Proton 6.3-4 and Proton 5.13-6, the Nvidia discrete graphics card does not work.
When using Proton 4.11-13 and Proton 5.0-10, the game works great, although the settings menu shows the built-in intel graphics, the discrete nvidia works. When using Proton GE, nvidia is displayed in the settings menu and nvidia is running.
Great Atmosphere but mediocre game. No Major Issues though. Used Proton 5.0-7.
would drop down to 29-56 FPS for a few seconds at a time. Didn't happen too often.
Bunch of very noticeable perspective aliasing shadow artifacts during the party inside the mansion.

Started working after setting "PROTON_USE_WINED3D=1 %command%" as command.

Runs out of the box flawlessly

Just finished playing the entire game. 60+ fps with zero crashing or stuttering. Make sure you disable the Compositor if using xfce. Not sure how it will fair with other DEs.

Works perfectly without any tweaks.

Performance seems fine so far, no massive frame drops (haven't played beyond the first house). Ultrawide works.

Heavy frame drops at times, even with Esync disabled and no SSAO.
