I think the disconnect here is, if your host is linux, there’s virtualization built into the kernel. You can use QEMU/KVM for virtualization at as close to bare metal as possible. My only loss is that’s I pass through 14 out of the 16 cores of my CPU. The virtual machine gets a physical dedicated 3090ti the host OS can’t touch. It’s less than 5% fps loss at any framerate, including the missing 2 cpu’s.
