Killer 7 Proton Experimental

A new Proton Experimental update was released with a few fixes for different games. CEG-protected games should be playable again, and Japanese text rendering for Killer7 has been fixed. We also have fixes for Crysis and Crysis Wars on newer AMD CPUs, and early support for 32bit OpenXR has been included.

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.
