I couldn't get Game Conqueror working on Bazzite. PINCE worked, but I couldn't use any existing CE configs, and saving my own didn't work the next time I loaded the game either. That could maybe just be a Silksong thing but I've never had that issue before.
Not a dealbreaker for Linux, but it was the one time I remember thinking "this is a lot easier on Windows"
You can adjust it in settings up to as many that will fit
