Facts

Purpose: vkd3d-proton aims to implement the full Direct3D 12 API on top of Vulkan and provides Direct3D 12 support development for Proton.github.com · 3 Oct 2026
Use: It is intended to be used as native Win32 d3d12.dll and d3d12core.dll drop-in replacements in Wine, including Proton, or on Windows.github.com · 3 Oct 2026
Priorities: The project prioritizes performance and game compatibility, using modern Vulkan features at the expense of compatibility with older drivers and systems.github.com · 3 Oct 2026
Driver requirements: The README lists Vulkan 1.3 and specific descriptor indexing, device-feature, and Vulkan-extension requirements for drivers.github.com · 3 Oct 2026
AMD support: RADV is the recommended and most-tested AMD driver, with Mesa 22.0 listed as the current minimum.github.com · 3 Oct 2026
NVIDIA support: The README recommends the latest NVIDIA drivers and states that at least the 535 series is needed.github.com · 3 Oct 2026
Intel support: The README says Intel GPUs have not been tested by the project.github.com · 3 Oct 2026
DXGI integration: vkd3d-proton does not supply DXGI components itself; it shares a DXGI implementation with DXVK 2.1 or later.github.com · 3 Oct 2026
Shader cache: It manages a driver cache for DXBC/DXIL-to-SPIR-V conversion, which the README says can reduce stutter and load times.github.com · 3 Oct 2026
Windows limitation: Native Windows use is described as mostly relevant to developer testing, and the README notes that many games only try to load d3d12.dll on Windows 10.github.com · 3 Oct 2026
Linux limitation: A native Linux binary can be built, but the README says it is not intended to be compatible with upstream Wine and is mostly for development.github.com · 3 Oct 2026
Development tools: The README documents developer debugging features including shader dumps and overrides, RenderDoc capture, GPU breadcrumbs, and descriptor QA checks.github.com · 3 Oct 2026
