What it is
vkd3d-proton is a translation layer that aims to implement Direct3D 12 on Vulkan and provide Direct3D 12 support development for Proton. It is intended to replace the native Win32 d3d12.dll and d3d12core.dll files in Wine, including Proton, and can also be used on Windows. The project puts performance and game compatibility ahead of support for older drivers and systems, relying on modern Vulkan features. Its README specifies Vulkan 1.3 alongside descriptor indexing, device-feature and extension requirements. RADV is its recommended and most-tested AMD driver, with Mesa 22.0 listed as the minimum; NVIDIA users are advised to use current drivers, with the 535 series as the minimum. Intel GPUs have not been tested by the project. vkd3d-proton does not provide DXGI, sharing that implementation with DXVK 2.1 or later. Its cache for DXBC/DXIL-to-SPIR-V conversion may reduce stutter and loading times. Developer tools include shader dumps and overrides, RenderDoc capture, GPU breadcrumbs and descriptor checks. Native Windows use is mainly described for developer testing.

Strong points and limits
Strong points
- Free, with no paid plans or listed price.
- Supports Direct3D 12 through Vulkan.
- Shader cache may reduce stutter and load times.
- Includes shader debugging and RenderDoc capture tools.
Limits
- Requires Vulkan 1.3 and specified driver features.
- Prioritizes modern drivers over older systems.
- Intel GPUs have not been tested.
- Native Linux builds are mainly for development.
Who it suits
It suits Linux or Windows users who need Direct3D 12 support through Vulkan in Wine or Proton, and developers working on related compatibility. Users should check their driver requirements first, especially on older systems or Intel GPUs.
Verdict
vkd3d-proton specifies its translation purpose, driver requirements and development tools in detail. Its modern Vulkan requirements and untested Intel support are important compatibility considerations.
