VMs do not have direct access to the physical GPU. Worse even is that the virtual GPUs on macOS are not accelerated. So for a VM your rendering will fall back on software based (CPU based) rendering.
Apple does not expose the APIs which are needed to be able to write a GPU accelerated driver for VMs.
IOW a VM is no good for playing games when using macOS.

(Disclaimer: I don’t actually use it for this purpose. And while it may be true that macOS guests can’t use accelerated graphics, someone looking to play older Steam games presumably has access to the Windows versions.)

- wila 7y agoI am talking about macOS guests, you are talking about Windows guests. It is not exactly the same thing. Yes, you can have accelerated virtual graphics adapters for your Windows guests on your macOS host. No, you cannot have accelerated virtual graphics adapters for your macOS guests on your macOS host. It is true that I could have worded that a bit better.
