Yes, this is correct. There seem to be a lot of people confused about the benefit of this in the thread, but it’s very simple: This tool exists essentially as a replacement for doing a full Hackintosh build of a system. You install Proxmox on a machine with a GPU, set this up, pass through the GPU and any other PCIe cards you want to run, and you’re in business.
It turns a days-long process into something that you can be up and running within like an hour. With OSX-KVM you have to set up the machine to be ready to do all the stuff like passthrough. This leverages the fact that Proxmox makes all that stuff super-simple.
It has to be AMD specifically, with some cards working better than others. Really old Nvidia cards work if you’re willing to go all the way back to High Sierra, though I haven’t tested it with this specific setup.
Intel iGPUs work on bare metal up until about tenth gen Core series, but I don’t know if you can pass them through with Proxmox.
