Welcome to the preview release for Cooperative Vector support in D3D12.  This exposes powerful new hardware acceleration for vector and matrix operations, enabling developers to efficiently drive neural rendering techniques directly from individual shader threads in real-time graphics pipelines. In research and in industry, machine learning based approaches have made their way to mainstream, replacing/augmenting The post D3D12 Cooperative Vector appeared first on DirectX Developer Blog.

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, Remedy showed The post D3D12 Opacity Micromaps appeared first on DirectX Developer Blog.

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.

Vectors have been supported as native primitive types in HLSL from the beginning. However, they have been limited to a maximum of 4 elements. This was reasonable for the use cases for which HLSL was designed as 3D vertices, 3D vectors, and RGBA colors can be fully represented using 4 scalar values or fewer.
