This is probably related to your hardware. I've been using Steam to play games -- Civ6, BG3, Pillars of Eternity -- and everything has worked fine across multiple computers and the Steam Deck. A big caveat here is that I've been using AMD everything, due to their Linux support being better, and also doing everything through Steam, because Valve makes stuff work well. I think that pre-Proton, Linux gaming was somewhat marginal -- some things worked, but a lot of AAA stuff didn't -- but these days, it's much, much better.
