vkd3d-proton

What vkd3d-proton is

vkd3d-proton implements Direct3D 12 on top of Vulkan and provides Direct3D 12 support development for Proton. It is intended as a drop-in replacement for the d3d12.dll and d3d12core.dll files in Wine, including Proton, or on Windows. It prioritizes performance and game compatibility by using modern Vulkan features, which can leave older drivers and systems unsupported. Driver requirements include Vulkan 1.3 plus specific descriptor indexing, device-feature, and extension support. For AMD, RADV is the recommended and most-tested driver, with Mesa 22.0 listed as the minimum; NVIDIA users need at least the 535 series, and the README recommends current drivers. Intel GPUs have not been tested by the project. vkd3d-proton does not include DXGI components, instead sharing a DXGI implementation with DXVK 2.1 or later. Its driver shader cache handles DXBC/DXIL-to-SPIR-V conversion and may reduce stutter and load times. It is free on Linux and Windows. Native Windows use is mainly described for developer testing, while a native Linux build is mainly for development and is not intended for upstream Wine compatibility.
