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’m also an avid gamer and have to say, Linux has come a long way. There’s so many options that help with running Windows native games that work out of the box. I’ve made the switch a while ago and even though I still have dual boot, I hardly ever boot Windows anymore. And I’m playing a wide range of games not only on Steam but also on the EA App, Epic Games, GOG etc. I see no performance issues (the games I previously played on Windows run just like there) and most games work without any tinkering. I cannot speak about Game Pass though.
