At GDC, Microsoft announced updates to its Windows software suite, including DirectX Raytracing 1.2 (DXR 1.2) and new neural rendering features, aimed at boosting visual quality and performance.
DXR 1.2 introduces Opacity Micromaps (OMM) for better handling of transparent objects, leading to up to 2.3x performance improvement in ray-traced games. It also includes Shader Execution Reordering (SER), which can make rendering up to 2x faster in certain situations by optimizing how the GPU processes shaders. Microsoft demonstrated that DXR 1.2 can improve performance by up to 40% in complex scenes, using Alan Wake 2 as an example. NVIDIA will support these features in their drivers, and Microsoft is working with AMD, Intel, and Qualcomm for broader adoption.
Microsoft is also adding support for cooperative vectors in Shader Model 6.9, allowing developers to use new hardware acceleration for vector and matrix operations, which helps integrate neural rendering. This includes Neural Block Texture Compression, which reduces memory use without losing visual quality, and techniques for enhancing real-time path tracing. NVIDIA will also support this with their Neural Shading SDK.
Additionally, Microsoft is updating Windows WARP, a CPU-based DirectX renderer, to fully support DX12 Ultimate, including ray tracing. They are also adding day-one support for DXR 1.2 in PIX, their DirectX debugging tool. These new technologies will be available in the preview Agility SDK in late April 2025.
