With more titles out and planned to release that will use DirectX 12, the VKD3D-Proton translation layer is another essential bit of open source tech and a new release is out now.
The what: paired up with the Wine and Steam Play Proton translation layers, VKD3D-Proton will translate Direct3D 12 to Vulkan and hopefully allow you to run some more advanced Windows-only games and apps on Linux. VKD3D-Proton is the Valve fork of the original project from the Wine developers, with a priority on performance and game compatibility.
Today VKD3D-Proton 2.1 went up which mentions that The Division should work (which they missed from the 2.0 release notes), Assassin's Creed Valhalla should also now work but it needs NVIDIA GPUs due to features lacking on AMD for now, and also the big one being Cyberpunk 2077 which is why it works in the latest Proton release.
In regards to Cyberpunk 2077 with VKD3D-Proton and Steam Play Proton, they mention in the release notes that this is mainly for AMD as NVIDIA drivers are missing the VK_VALVE_mutable_descriptor_type extension which accidentally works around some fatal bugs within the game itself. Cyberpunk 2077 does work on NVIDIA GPUs but it will randomly hang and issues are likely to change over time since it's a new game, with a lot of bugs.
This release also has various other fixes for the likes of Horizon Zero Dawn and DIRT 5, there's multiple performance improvements, and other misc improvements.
