Hey I will give my anecdotal recent experience. Several months ago I switched to Pop! OS and have had basically no issues. I have an Nvidia GPU and I play a lot of games. I don’t play any games that are blocked by anti cheat (not because I can’t, I just don’t happen to play the few that are blocked).
I spent the first day getting everything signed in, installed, set up and tweaked to how I like it with very minimal terminal usage. Mostly gui and clicking.
Steam+Proton along with lutris makes it easy to play any game for me.
Side note: I have 4 monitors of varying resolution, size, orientation and refresh rate and it hasn’t caused problems other than the initial setup (I used cursr to help with this)
Oh God I didn’t even think about monitors. I only have one but it’s the stupid big ultra wide by Samsung. I honestly play most games in windowed. Wondering if there’s resolution support on the actual os though. The rest is like…5120 x something.
I’m running Ubuntu and never had an issue with 5120x1440 on a stupid big ultrawide AOC.
