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.

In the next update to Windows, codenamed 19H1, developers can specify DXR state subobjects inside a DXIL library. This provides an easier, flexible, and modular way of defining raytracing state, removing the need for repetitive boilerplate C++ code. This usability improvement was driven by feedback from early adopters of the API,
