The features requires shader model 6.5 and therefore a version of [DXC](https://github.com/Microsoft/DirectXShaderCompiler) that supports that model or higher. The Shader Model 6.5 requirement also means only DXIL binary format is supported. + +There doesn't not appear to be a similar feature available in Vulkan yet, but when it is available support should be addeed. + +For CPU targets there is the IFeedbackTexture interface that requires an implemention for use. Slang does not currently include CPU implementations for texture types. + |
