I'm sorry I just may not understand. My point is that even graphic intensive games also are compute (CPU) intensive, so significant performance differences is where it matters. Webgl, WebGPU, wasm all execute shaders on the GPU I don't see the overhead to be critical and of much interest to benchmark. I could be wrong and some drastically different results could be observed but what I've read on the subject indicates it won't. Or I don't understand what you mean.
