Re: People stopped dual-booting 20 years ago.
GPU related things work reasonably well in virtualisation, but you need to use PCI passthrough if the emulated accelerated graphics adaptor isn't good enough.
In order of ease of use ESX passthrough does work, as does KVM (KVM is definitely the most functional solution, slightly harder to set up). Xen also works, but passthrough to NVidia cards needs a Quadro or some unsanctioned patches, AMD cards work with caveats usually as a secondary card to the emulated primary.
When passthrough does work, it works well, and fast.
