New in D3D12 – GPU-Based Validation (GBV) is now available for Shader Model 6.x
In the next update to Windows, codenamed 19H1, the DirectX12 debug layer adds support for GPU-based validation (GBV) of shader model 6.x (DXIL) as well as the previously supported shader model 5.x (DXBC).
GBV is a GPU timeline validation that modifies and injects validation instructions directly into application shaders.
