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.
You can always dual boot and use Linux for whatever you like it for. Sadly Windows is still the go to thing for gaming, since it’s the target platform for 99.99% of software and especially games.
Proton/Valve has made a lot of headway here. Mostly I’m seeing mmos/Destiny 2 being the only big holdouts anymore, but the niches I am in have tended to have good Linux support for quite some time.
