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)
Tangentially related: I’ve had this exact problem with quite a few games. Most recently, Subnautica: Below Zero. I often pause a game, go take care of a chore or something, then come back to having no controller input. Only recourse seems to be to exit the game and start it back up again. Using an 8bitdo Ultimate (non bluetooth) controller at the moment, Steam Deck connected to the official dock.
Anyone else have this issue? Any remedies you’re aware of?
I have this problem with Skyrim and Fallout 4 if I use an external controller (either USB or Bluetooth) when docked. If the controller gets disconnected or I touch any of the Deck’s own controls when playing, the game will just completely stop listening to the external controller and will only work if I use the Deck’s controls. Restarting the game does fix it but it’s pretty annoying, and eg. toggling steam input off and on doesn’t do anything and the controller order is correct.
Maybe try turning steam input on or off? That’s the first toggle I’d reach for with controller issues (like when Elden Ring came out).
