I use Proxmox and GPU passthrough works just fine (via QEMU). Note that Nvidia GPUs have less issues with passthrough, at least last I checked. See this guide: https://pve.proxmox.com/wiki/PCI_Passthrough

But if you’re running a standard distro, there are guides for most them.

* Arch guide (excellent resource, applicable to all distros): https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF

* Ubuntu: https://ubuntu.com/server/docs/gpu-virtualization-with-qemu-...

* Gentoo: https://wiki.gentoo.org/wiki/GPU_passthrough_with_libvirt_qe...

You can also find countless blog posts and videos on setting up GPU passthrough.

One excellent resource for gaming use-cases in particular is this subreddit: https://www.reddit.com/r/VFIO/

Last thing to note is that your motherboard can make the process easier if it has good IOMMU support. Basically, you want a MB that puts your PCI slot in a separate IOMMU group. You can find examples by searching for “(MB name) IOMMU groups”.
