Mesh Shaders and Primitive Shaders: Replacing Fixed-Function Vertex Pipelines: Competitive Benchmark Analysis and Hardware Interactions

[Liam Rivera]

I’ve been benchmarking mesh shader implementations across RDNA3 and Ada, and the geometry amplification headroom is real, but the frametime spikes in micro-polygon scenarios are wildly inconsistent between drivers. When you’re culling LOD dynamically at 240Hz, even a 4ms draw dispatch stall on the mesh pipeline is noticeable in competitive play
