Had an early bug with GE Proton that restricted the use of the sign menu so it wouldn't scroll, but that has since been fixed and works well. Didn't anything out of ordinary. Looks and performs well.
Finished game without issues
Works good out of the box. Completed the game from chapter 1 to chapter 5 without any problems or crashes.
Runs fine as on Windows.
Runs perfectly, played through the full game.
Some minor lighting issues
Game is playable with some minor artifacting. Frequently crashed at loading screens. Annoyance but not a complete showstopper.
Some minor lighting/shadow issues
Seems there's about a 50% chance of it to crash at load screens.
Runs almost perfect OOTB, some minor lightning oddities (but i don't know if they aren't also on windows)
couple of odd crashes, but I'm not convinced it was the game itself and not something in my OS going on. normally very stable and smooth under proton 4.11-2
I didn't experience any of the problems described in older reports. Runs out of the box without any problems for me. ~55 average fps with everything maxed out at 3440x1440.
Game starts minimised. Cursor usually doesn't work but is fixed by using the arrow keys to navigate through the options and setting the game to borderless windowed mode. On medium graphic settings the game averages between 50-60 fps. Has some small graphical issues but is playable to end without any crashes experienced.
Mouse controls wont work
You should use the Proton version that comes with the game. You can test newer Proton versions but if there's a problem fall back to that one. Game fully playable to end. A bit worse performance than Windows so you'll need a little bit lower settings. You may or may not experience some additional problems such as it being minimized on start, etc.
Some slight visual artifacts occasionally
