Platform and API support for Dawn/Tint

Khronos's Vulkan

Vulkan is supported with minimal features, limits and extensions being required (what's required has been measured to be widely available). Vulkan is the preferred target API on platforms that don't have other "modern" GPU APIs. Vulkan is supported as best effort on other platforms (e.g. Windows and macOS).

Required version: Vulkan 1.1.

Required features: depthBiasClamp, fragmentStoresAndAtomics, fullDrawIndexUint32, imageCubeArray, independentBlend, sampleRateShading, and either textureCompressionBC or both of textureCompressionETC and textureCompressionASTC_LDR.

Required limits: they are too detailed to describe here, but in general should be widely supported. See the WebGPU limits that mostly correspond to Vulkan limits.

Operating system support:

  • Linux: Supported.
  • ChromeOS: Supported.
  • Android: Work in progress.
  • Fuchsia: Work in progress.

Microsoft's D3D12

D3D12 is supported with feature level 11.1, or feature level 11.0 with Resource Binding Tier 2. This is the vast majority of D3D12 devices. Supported shader models are 5.1 and above. It is the preferred target API when available.

Windows flavor support:

  • Win32: Supported.
  • UWP: Supported, best effort.
  • Xbox: Not supported, contributions welcome.

Apple's Metal

Metal is supported and is the preferred target API when available.

Apple OS support:

  • macOS: supported on version 10.15 and above.
  • iOS: supported, best effort.
  • tvOS/ipadOS/...: Not supported, contributions welcome.

Khronos's OpenGL family

Support for OpenGL is in progress with the aim to make OpenGL ES 3.1 (with extensions and limits) supported through EGL. Other flavors of OpenGL (desktop OpenGL) or binding APIs (GLX, WGL, EAGL, CGL) are supported as best effort with contributions welcome.

Microsoft's D3D11

A work-in-progress D3D11 backend is available but not considered ready for production uses yet.
