D3D12 Opacity Micromaps

DirectX Raytracing (DXR) now supports Opacity Micromaps (OMMs), enabling hardware to handle alpha tested geometry more efficiently than relying only on costly AnyHit shader invocations. At GDC 2025 DXR 1.2 was announced including OMMs, and you can see it discussed in this: GDC DirectX State Of The Union YouTube Recording. In the video, Remed...

D3D12 Shader Execution Reordering

Shader Execution Reordering (SER) is an addition to DirectX Raytracing that enables application shader code inform hardware how to find coherency across rays so they can be sorted to execute better in parallel. At GDC 2025 DXR 1.2 was announced including SER, and you can see it discussed in this: GDC DirectX State Of The Union YouTube Record...

Agility SDK 1.716.0-preview & 1.615-retail: Shader hash bypass

The D3D runtime as of 1.615 officially supports applications opting to bypass shader hash validation. The historical purpose of the hash that the DX shader compiler embeds in every shader binary was to give the D3D runtime to confidence that shaders being given to it are well formed.  The assumption was that a hashed shader likely came from an o...
