Meshlets and Mesh Shaders

Mesh shaders, introduced in NVidia Turing and AMD RDNA2, enhance the GPU geometry pipeline by replacing several fixed function units and shaders with a more flexible, programmable system. This allows for finer control over geometry processing and culling. Mesh shaders, working with smaller meshlets, can improve rendering efficiency and reduce pipeline bottlenecks. This post explores their performance benefits and potential, showing how they can outperform vertex shaders in specific scenarios.
