*3D acceleration in hypervisors 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 resulting VirtualBox [[Hypervisors#Graphics|supports for OpenGL are slightly better than Direct3D]] (since it doesn't have to be reverse engineered), on the other hand VMware has better support for D3D9. Keep in mind that most Windows games (including ports) use Direct3D.

Before diving in, using WHPX for hardware acceleration on Windows host [https://www.youtube.com/watch?v=T43ni7mssww&lc=Ugw2qKkJVn3eSW7ZJ0p4AaABAg.9g4VM28d9_o9kUveV6vMMD will be much slower performance wise compared to using QEMU with Linux host and KVM]. You will have to stay with QEMU TCG entirely until you manually switched to 'ACPI PC' kernel. The starting 'ACPI Uniprocessor' kernel does not boot on QEMU WHPX.

:qemu-3dfx builds advantage is "MESAGL/3Dfx Glide pass-through". The project took on the troubles to support the legacy of vendor-specific OpenGL extensions that matter for PC games. Past and existing solutions (VirtualBox VBoxVGA's ChromiumGL, VMware SVGA3D and QEMU Virgil 3D) are all based on API "re-rendering" rather then "direct forwarding".<ref>[https://github.com/joncampbell123/dosbox-x/issues/3405#issuecomment-1328235348 javispedro's comment about Virtual GPU adapters]</ref><ref>[https://www.youtube.com/watch?v=TsszZ260o2g KJ Liew's "QEMU Star Wars: Knights of the Old Republic (2003) -- Tribute to NVIDIA OpenGL" video description]</ref>See [https://github.com/kjliew/qemu-3dfx/wiki/QEMU-3D-APIs-Pass-Through QEMU 3dfx wiki: 3D APIs Pass-Through] and [https://www.youtube.com/@qemu-3dfx/videos KJ Liew's YouTube channel] for more information about qemu-3dfx.

You don't have any other option except "QEMU-3dfx with WHPX" OR "Type 2 hypervisors" for current Windows hosts at the moment.

These are emulators in the truest sense, in that they don't do any kind of "cheating/hacking" the way a hypervisor would. But keep in mind that, unlike [[Wikipedia:X86_virtualization#Hardware-assisted_virtualization|hardware-assisted]] [[#Hypervisors|hypervisors]]; emulating something like Voodoo3 with Pentium II level of hardware with these software emulators requires latest and greatest top-notch [https://www.cpubenchmark.net/singleThread.html single thread performance of CPUs]. [[PCem]], [[86Box]] and UniPCemu are full retro x86 computer emulators, spanning from the original IBM 5150 to Pentium II powered PCs. Setting it up is much like building an actual retro computer, but in software, so expect it to be as difficult as setting up an actual retro PC. This means you're going to have to install Windows 2000/XP (Vista is supported by them but unrecommended) along with all necessary drivers for the hardware you chose. Having said that, see these emulators as a useful alternative way to emulate these operating systems especially if you want the most accurate and compatible option for 3Dfx Voodoo emulation and [https://www.vogons.org/viewtopic.php?t=534 Windows 2000/XP glide games].
