Completed the game with no compatibility issues.

50 hours/4 full playthroughs and didn't run into any issues with Proton Experimental.

needed unreal framework
tested from demo version

May or may not because of running it on Linux, maybe just bug from the game.
Performance is sub-optimal, typical unreal engine games, some graphical "defect" that comes with the engine. Run a little bit worse than it is on my windows machine, not really noticable, but it also maybe just because the game sub-optimal optimization.
GAME RUNS "PERFECTLY" OUT OF THE BOX WITHOUT THINKERING.
Some may experience gpu overheating issues, if so just limit your maximum FPS to smth more reasonable...

Window scrolling was choppy on Ultra settings (default). Changed settings to High and set motion blur to zero and it was a lot better. This could just be my graphics card not being up to the task
All attempts (two) to run on Proton 6.3-2 failed, switching to 5.13-6 worked
Gives A fatal error message box on start.
Whenever my computer went idle and locked, after waking it up, the game wasn't running.
Runs smoothly out of the box on ultra settings
Minor mouse lag; fixed by enabling hardware cursor in game settings

Plug'n'play
Some crackling in music after combat. Disabled music ;)
