As much as linux for PC gaming has made huge strides over the past few years, it seems really hard to avoid having a dual boot to keep windows available if you're serious about the whole breadth of available games. Or if you want to avoid pitfalls on those titles that run with a list of caveats, you can go exploring on protondb and some games need a collection of commmandline tweaks to get going well. It'd be nice to have a better experience for enabling those or opt-in to commonly used configs on particular games
Maybe I'm cheating by using a 1080P monitor, but I have only ever installed Windows once and that was for Starfield since it didnt work with Proton OOTB, once they fixed it, I purged and havent gone back. In the future I wont be doing that. I love Bethesda games, so in the future I'll just wait it out. I did make sure to play the heck out of it while I was on Windows though.
In hindsight, I really didn't need Windows, but I was impatient.
