Besides rocket league.
Chivalry II works great on Steam Deck and I exclusively play it on there now to save space on my PS5. Big learning curve if you’ve never played Chivalry 1 or Mordhau but it’s addictingly brutal and fun
yugioh master duel or magic the gathering arena
Halo infinite
How well does it run?
Using proton ge the latest one , and can play 3-4 matches before it freezes the screen, so have to quit the game and restart it , other than that, graphics and all are pretty good, 45-55 fps and 60 fps on some less demanding arenas.
I don’t think I would play a game that requires me to restart it every 4 games.
Farlight 84, 60 FPS on highest settings.
It’s pretty much mixture of Fornite and Overwatch.
Overwatch 2 works great at 1080p 60fps
Omega Strikers
Street fighter 6
Counter Strike 2. I can get 60fps on my crappy laptop with Intel UHD 620 graphics, albeit at less than 1080p.
Overwatch 2.
