Proton GE needed for the intro video to not be a black screen. Can be skipped by pressing a button without GE.
Unsure if linux specific bug or not
I am unsure what is causing my issue. I think loading save file on another map than the first breaks the game.
Can't load save file after I saved on second map. Can make new save file and play, unsure if some linux specific bug or not. Seems the game loads the first map but tries to place character on second where I saved. Then crash
Flawless, I have not tried it on windows but I see no issues on this game.
Excellent performance. I have not had any noticeable issue whatsoever, works out of the box for me. I have not tried running on windows but it runs smooth. I would say amazingly but it is not a heavy game that needs a powerhouse to play. It's performance could probably not be better. If it runs better on a windows machine I will be genuinely surprised.

There is occasional hitching when needing to load new environments, but it clears up relatively quickly and is consistently good.
Once it's running, it can hold a consistent 1080p60fps with my 960M. Any framerate issues can be traced to the age of my hardware.
