All I do is watch some vids and game. I have only come across one game I can’t get to play and it’s flight simulator x. If steam says it’ll play on steam deck, you’re 100% golden. If it says unsupported, do a quick web search for protondb and search the game there. I’ve played a few that steam said wouldn’t work and they do. As far as how well they play, it’s been awesome, no complaints. I’m a linux newbie and don’t know shit and it’s been painless. I did try mint and nobara, and had issues trying to get mint to play games, and nobara worked good but after a week I lost my sound and I liked the way the workspaces works much better with popOs
