The benchmark is released: https://gravitymark.com/
Such emulation is working poorly with Metal:

The same HW (eGPU with Vega 56) result is more than two times worse for Metal than the result on Windows / Linux.
We have the same multi_draw_indirect_count () emulation for Nvidia / Intel running on Direct3D11 and all cards running with OpenGLES API.
And somehow, emulation is working much better than Metal and sometimes even faster than a single API call.
