I decided about three years ago to give “100% Linux” gaming a go for a few months, since I was fed up with Windows shitting itself on a dual-boot system, see how I got on. Never went back. It does help that I’m not in to MMOs or things which require anti-cheat, since that’s a stumbling block, but it’s rare that I even check protondb before purchases now, nearly everything just works and it keeps getting better.
