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.

There's an ongoing effort to get macOS installations working on hypervisorsthat run on non-Apple hardware. Support Such support has historically been low or non-existent since Apple makes no effort to support standard PC hardware. Some people have gotten this to successfully work on KVM/QEMU, with an example/setup guide for Debian/Ubuntu hosts being available [https://github.com/kholia/OSX-KVM here]. However, running macOS on hypervisors running on actual Mac hardware is natively supported by hypervisor software like Parallels Desktop or VMware Fusion. ===Obscure, Abandoned, Beta or Experimental Operating Systems===Despite many of the common operating systems including legacy ones such as MS-DOS, OS/2, Novell Netware, etc. are being supported by modern hypervisors, some obscure (e.g. [https://templeos.org/ TempleOS]), abandoned (e.g. [https://ja.wikipedia.org/wiki/%E8%B6%85%E6%BC%A2%E5%AD%97 Chokanji 1~4]), beta or experimental (e.g. [https://betawiki.net/wiki/Windows_95 Windows "Chicago" Beta]) operating systems may still fall out of the range and having issues, especially when relying on specific hardware configuration or old quirks that no longer presents in modern PC hardware. Using a low-level [[Intel CPUs]] emulator to run these operating systems may ease out such problems compared to hypervisors.
