[metal/compute/hlslcc] Significant CPU and GPU frametime regression with certain projects
There are significant performance regression on metal/compute/hlslcc when compared to trunk or 5.4/release:
With modified 'Viking Village (2014)' project:
(~75/93) vs (56/37) - (metal/compute/hlslcc) vs (trunk) - GPU/CPU
on GPU, all shaders are way slower (besides gpu frame looks more or less the same).
on GPU, according to Unity’s profiler, Camera.Render->Drawing is around ~26ms vs ~20ms. the rest is used up by Gfx.WaitForPresent 55ms vs ~35ms.
With the project from case 761024:
there is no significant regression in GPU frametime, but a similar regression on CPU.
This is not reproducible with all projects i.e Survival Shooter. Standard shader performance and mobile torture test results also seem to be similar.
