A new Proton Experimental update was released earlier today that makes some new games playable, as well as a demo, and fixes up some issues here and there. Stronghold Crusader: Definitive Edition demo and Atelier Reseriana are both now playable, while battle.net installations have been fixed. There was also a Proton regression that fixed the performance degradation that we saw in Dirt Rally 2.
The new Proton Experimental update should automatically download if you already have the experimental layer. If not, just search for Proton Experimental in the Steam store on your Steam Deck and download.
