Split/Second Proton Experimental

There was a new Proton Experimental update this morning that brings up some fixes and improvements. This includes fixes for Far Cry New Dawn, Dark and Darker, The Talos Principle, Dungeons and Dragons: Chronicles of Mystara, and Squad. We also have improved controller support for Far Cry, Binding of Isaac: Rebirth, and Split/Second when Steam Input is used and controller hotplugging is now more reliable. There are also a couple of new playable demos, as well as The Rabbit's Scroll and Blair Witch VR now being playable.

The new 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.
