Earlier this week, Microsoft announced its latest DirectX 12 Ultimate API which aims to provide a unified platform to developers for next-generation graphics on PC and consoles. One of the key features of the announcement was the addition of Mesh Shaders to the DX12 framework & the Principal Engineer at Microsoft/Xbox ATG (Advanced Technologies Group), Martin Fuller, has showcased how the new technique would help devs in delivering higher graphics throughput in next-gen games.

Martin explains that there are only two platforms that currently support DirectX 12 Ultimate Mesh Shaders, and those include the NVIDIA Turing GPU lineup and the Xbox Series X with AMD RDNA2. So just a recap of what Mesh Shaders are and what they do. NVIDIA announced Mesh Shaders back with its Turing GPU architecture in 2018 as a means to dramatically improve performance and image quality when rendering a scene with a substantial number of very complex objects.
