The next Proton 10 Release Candidate is here to publicly test, and it is bringing over tons of fixes from the Experimental branch, giving the compatibility layer that allows us to play Windows games on Linux even more compatibility! Proton 10.0-4 RC brings in multiple new playable games, including Fellowship, Metal Slug: Reawakening, Distant Worlds 2, and Drop Dead: The Cabin. We also have a multitude of fixes for Far Cry 5, ARC Raiders, Cladun X3, Tempest Rising, Assassin's Creed Shadows, Secrets of Grindea, The Finals, Tekken 8, and much more. And of course, Proton's components have also been updated.

You can try out the new layer for yourself by searching up "Proton 10.0" in your library, then going into the Steam properties and changing the beta to the "release-candidate" branch. This should automatically redownload the layer as the new 10.0-4 version.
