there's probably a big asterisk there. the correct term is probably "fast enough"

virtualization adds very overhead, a Windows VM running with a dedicated GPU can get 95% of the host's score on 3dmark.

the biggest issue on these cases is IO which can be handled in a few ways.

Missing word?

"Very little"? 5% is enough to turn this year's high-end machine into last year's model.

Nested virtualisation is also a thing now, and 5% per layer adds up fast.
