I play on steam deck. it’s really good for long grind seasons. less damage to tendons on wrist.
plus I get 60 fps on it. no RTX f course but still do able. You do need add ons like consoleport to setup buttons. and enable action targeting. FSR, and VRS help maintain the fps. the big issue is healing it’s to mouse ui controlled to be practical. but that said you can touch screen or enable via console commands the friendly action targeting mode. this way look at target press button to heal them.
if blizzard would do a decent console ui port. it would work great on steam deck. for now I’m running some of my own custom tweeks via addons.
