Starlight Re:Volver Proton Experimental

A new Proton Experimental update was released to make some new games playable and fix some older titles. Act of War: Direct Action and Starlight Re:Volver are both now working with this layer, while Alone in the Dark (2008), DiRT, and Prototype 2 should run on CPUs with a high core count. This update also fixes Disgaea PC not displaying controller icons correctly and fixes more videos in VRChat.

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.
