Direct3D Cooperative Vector is Evolving DirectX continues to evolve to support the growing demands of AI and machine learning workloads. As part of this effort, we plan to introduce an expanded suite of linear algebra capabilities in a future Shader Model release, unlocking even more robust GPU acceleration for bedrock AI/ML computations within th...

This year at gamescom, Microsoft is highlighting new gaming features coming for Windows, particularly for handheld devices. We want to highlight one of the DirectX team’s most exciting new contributions to the PC gaming ecosystem, which will make its debut on the new ROG Xbox Ally and ROG Xbox Ally X. Advanced shader delivery addresses one of th...

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 ...

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...

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...

Today DirectX 12 provides APIs to support GPU video encode acceleration for several applications, as detailed in D3D12 Video Encoding - Windows drivers | Microsoft Learn previous blog posts such as Announcing new DirectX 12 feature - Video Encoding! - DirectX Developer Blog. In this blog post we’re happy to announce a series of new features incl...

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...
