Two vital open source projects for the Steam Deck had new releases today, with the DXVK and VKD3D-Proton layers that translate Direct3D / DirectX to Vulkan.
With these two, Proton that runs Windows games on the Steam Deck and Linux desktops should see some nice improvements with a future release. I won't go over all the changes, as it's aimed at quite a technical audience but for us regular users here's a few highlights.
Some of what you can expect to see thanks to DXVK 1.10 include better performance for Assassin's Creed: Origins, Elex II, God of War, GTA IV, Quantum Break, Resident Evil 0, 5, 6, Resident Evil: Revelations 2, Total War: Warhammer III and others. There's also a few bug fixes for specific games like Arma 2 fixing texture issues and Black Mesa lighting issues.
Over on VKD3D-Proton 2.6 you can expect to see a fix for a black screen rendering bug in Horizon Zero Dawn, a startup crash fix for Final Fantasy VII: Remake and Warframe, multiple crash fixes for Guardians of the Galaxy when interacting with certain game objects, Elden Ring shouldn't hang on shutdown and broken geometry rendering in Age of Empires: IV.
Other VKD3D-Proton improvements reduce loading times in Monster Hunter: Rise, Guardian of the Galaxy and Elden Ring. There's also a workaround for DEATHLOOP menu flicker on the AMD RADV driver, a workaround for "quirky API usage" in Elden Ring, sorts out glitching foliage in Horizon Zero Dawn and another workaround to help "some questionable UE4 shaders".
