Seems to work flawlessly when using Proton 9.0-3 w/o gamescope or other tweaks
Works as it should. No major compatibility issues from cutscenes, reaching the menu, or starting and playing the game
gamescope -f %command%
Install and run with gamescope - as per launch options - to fix cutscene/video playback issues (for Debian or other Debian-based distributions, you can install package version 3.15.3-1 from Debian's experimental repository - https://packages.debian.org/experimental/gamescope).
If not using gamescope, no other issues besides cutscene playback occur. The issue with cutscene playback is also known to similarly occur on modern Windows systems.
Works out of the box with Proton 9.0-3
Had no major compatibility related issues while running the game.
Essentially works without issue
For my system, I've noticed using the steam overlay for some time in a session causes a moderate frame rate drop for the rest of the session. If encountered, this can be fixed each time by restarting the game.
