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.

Needing to run games on the same machine as your server is IMO not the most common use case. It tends to be expensive if power bills are a concern and using a VM as your main machine is tricky IMO.

Most games using anticheat won't run on VMs without a fight too. Your Proxmox supports taking a memory snapshot and restore, which would allow most cheats to work if they are convenient enough.

For every person like your brother we have many more half-serious people who need some type of reward before committing more mental effort. Wtf is a storage pool? What do I do with all these clusters, high availability thing it keeps asking about? Flattening out the learning curve is a nice benefit on its own.
