Sea of Thieves Proton Experimental

The next Proton Experimental update dropped a couple of days ago, and it brings some nice improvements across the board both for bigger Linux computers with high CPU core counts and the Steam Deck! On the Steam Deck, we have Sea of Thieve's videos working again, and Borderlands GOTY is playable again, while videos for The Finals are now working again, too. We also have some new playable games, like Snares of Ruin 2 and Iragon, while Joe Danger 1 and 2 will no longer crash on AMD GPUs!

The new update should appear in your downloads automatically when you boot up the Steam Deck.
