It causes a bunch of weird controller errors, such as when a controller disconnects (or if the deck goes to sleep), it can’t reconnect again.

Just let it use the default version (which I believe should be Proton Hotfix, or whatever Valve decides it should be since BG3 is an AAA headliner, they’ll want this to work)

  • I’m playing it on Steam Deck right now and though I’m still only a few hours in, I’ve only had some very minor issues. The game plays fine!

    Issue 1: The graphics settings don’t seem be persisted. I have to manually activate anti-aliasing every time, or deal with jaggies.

    Issue 2: On Proton Experimental, my controller didn’t work at the start. I was able to fix it by launching the on-screen KB (Steam button+X), hitting “Enter”, and then switching back to controller mode. Sounds like it’s time to switch to Proton Hotfix.

    Otherwise, it’s been great! I left the graphics settings (other than AA) at their defaults and I’ve seen no noticeable lag or stuttering during play.

      • I fiddled with it a fair bit, and ultimately decided to just stick with the “Medium” default. With that, it’s pretty stable, with a few dips, but given the turn-based combat etc, it doesn’t really bother me.

        (But that said, I’m an old-school PC gamer. I played DooM on an 8 MHz 386 at sub-10 FPS. I had to “lead” my shots to play. So my personal standards for game performance may be a little low.)
