The Steam Deck ran it surprisingly well, to be honest. I used the settings off this page and it ran at a pretty solid ~40 FPS.
Not my favorite game, but it was pretty and fun to jump around hacking people as I hacked at people (with a katana). Story was ok, and the ending was just a bit meh for me, but worth it in my eyes.
Next I’m on to playing Outer Wilds docked to the TV with my partner. I’m a few cycles into it and am hooked. The Steam Deck was an excellent buy!
Recently finished outer wilds on the deck, and now I’m working through the dlc. If you’re hooked, you are in for a ride. My advice is don’t look at walkthroughs if you have the patience. Sometimes if you stare at the problem for long enough it might just solve itself. ;)
