Sorry, I don't think I implied virtualising the GPU is the problem.

I said "the fact that it's a VM has caused performance degradation enough that graphical fidelity was diminished" - this is an important distinction.

To clarify further: the GPU and CPU is a unified package and the request pipeline is also shared, working overtime to send things to RAM will affect GPU bandwidth, so overhead of memory allocations that are non-GPU will still affect the GPU due to that limited bandwidth being used.

I never checked if the GPU bandwidth was constrained by the hypervisor to be fair, because such a thing was not possible to test, the only corrolary is the PS4 which we didn't optimise as much as we did for DX and ran on slightly less performant hardware.
