TFA's author is using GPU passthrough to get Windows to run games with anti-cheats that won't work under Linux. So you want full hardware virtualization with GPU passthrough for that to work: several hypervisors would do but Proxmox is Debian+hypervisor+LXC+ZFS and it is easy to use.

I got my brother, who's not a techie and who lives at the other end of the world, to install Proxmox and get GPU passthrough working.

Proxmox is basically Debian.

Proxmox allows to do things that are totally overkill for beginners indeed but it's still simple to use for simple stuff.

I think we should encourage beginners, like my brother, to use solutions like Proxmox, not discourage them.
