An example use of AMD FidelityFX Variable Shading exists within the Xbox Game Development Kit samples.
Optimized for Shader Model 6.0+
Open source, MIT license
Features of the implementation:
- AMD RDNA™ 2-optimized algorithm.
- Support for Direct3D®12 API.
- Shaders written in HLSL utilizing SM 6.0 wave-level operations.
A sample application is provided for Direct3D®12.
|Full Shading Rate||2×1 or 1×2 Shading Rate||2×2 Shading Rate|
