DirectX 12 Ultimate adds powerful new features and capabilities to DirectX 12 including DirectX Raytracing Tier 1.1, Mesh Shaders, Sampler Feedback, and Variable Rate Shading (VRS). After DirectX 12 Ultimate was announced, we started adding new tests to 3DMark to show how games can benefit from these new features. Our latest addition is the 3DMark Mesh Shader feature test, a new test that shows how game developers can boost frame rates by using mesh shaders in the graphics pipeline.
