With the advances in gaming on Linux in recent years, it is so tempting to switch full time. I would absolutely love to, but I am a Game Pass Ultimate subscriber and it is where I play a lot of my games on PC. I know you can use the cloud version, but I cannot stomach streaming games in their current state, so it is a no go. A large portion of my Steam library is compatible, but anytime I have done an install I end up giving in and going back to Windows for games.
I’ve been Linux fulltime for years, settled on Pop!_OS for it’s excellent NVIDIA graphics integration. As far as game compatibility goes, check your games on ProtonDB. Even if they don’t have a Linux native version, the Proton Compatibility Layer may let you play your “windows only” games on Linux without streaming.
