# 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 wildly 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 1.0 is supported with some required extensions (`VK_KHR_maintenance1`), or Vulkan 1.1 and above without extensions.
|
||
|
|
|
||
|
|
**Required features**: `depthBiasClamp`, `fragmentStoresAndAtomics`, `fullDrawIndexUint32`, `imageCubeArray`, `independentBlend`, `sampleRateShading`, and either `textureCompressionBC` or both of `textureCompressionETC` and `textureCompressionASTC_LDR`.
|
||
|
|
|
||
|
|
**Required limites**: they are too detailed to describe here, but in general should be wildly supported.
|
||
|
|
See the [WebGPU limits](https://gpuweb.github.io/gpuweb/#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.
|
||
|
|
- 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 D3D12
|
||
|
|
|
||
|
|
Dawn doesn't have a D3D11 backend at the moment, but D3D11 support can be achieved with the OpenGL ES backend through ANGLE's OpenGL ES to D3D11 translation.
|
||
|
|
There might be a D3D11 backend in the future.
