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)
It work well but i stopped because the UI is small.
I played the EA on steam deck, and it was awesome. However, i’m waiting for improvement on the UI side so i can fully enjoy the game.
As for mapping control, i use the DOS2 and i tweaked it to suit my taste.
