It’s a great time to game on linux. I my personally use arch and everything works fine for the games I play be it with steam and lutris. I also have an nvidia 3080 and it works fine.
I recommend pop! Os for your first distro. It’s a very good distro that is newb friendly and it’s ready to go from the first boot.
It’s a perfect time to get your toes wet and there’s plenty of places to get help when your stuck. The popos subreddit is full of people with the knowledge to help and most important here at lemmy.
I have a 3080 with a 5900x at 1440p under arch and the game runs very poor, nowhere near as it should. It’s just not an optimized game.
