Hypervisors don't have direct access to the graphics hardware with exception to few exceptions including Virgil/Virtio GPU available in QEMU (only works with Linux guests)and VMWare ESXi GPU passthrough, which means graphics card emulation is less than ideal for video games that use 3D APIs. However, 3D acceleration in hypervisors today is capable of running fairly demanding video games or other 3D applications with a few drawbacks such as limited DirectX API versions. Every hypervisor has a different approach to handling 3D graphics; none are by any means performant enough , and most of the time companion programs such as VMware Tools have to run modern video games without resorting to hardware passthroughbe installed in virtualized operating systems. Support Supports for OpenGL is are slightly better than Direct3D since it doesn't have to be reverse engineered, but most Windows games (including ports) use Direct3D.
