The regular old af Big Picture mode should work fine but it’s ugly and clunky imo. The new steamdeck specific big picture mode (or rather session) doesn’t work. I just get a black screen. That might be fixable but I haven’t dug into that yet. It should be able to work with current drivers. Wouldn’t be as complicated with AMD graphics and I’m looking if I find someone to trade my 1650 with an RX 6400…
