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)
That really depends on the person, this is a turn based RPG, I don’t mind playing on 30fps if I don’t have to react quick to things.
I’m having a blast on the SD, definitely worth the purchase.
