I'm using it in conjunction with PCI passthrough instead of dual boot.
I've been running Windows 10 for more than a year now and played all kinds of AAA titles successfully. The performance-loss seems minimal.
Recently I managed to get a second GPU and spin up another VM, so now me and my partner can play on the same machine, heaving each a keyboard, mouse and screen.
Do you have any hints on how to set up a similar system? Links, guides, gotchas, whatnot? I've seen someone mention this setup before (perhaps it was you?) and I'm sure I'm not the only one interested in running something similar.
I do the same, I used to run my VMs off of ZFS with spinning disks, but that was too slow at times, so my last upgrade has been giving the VMs their own SSDs and that has worked out great, I then backup the VMs to ZFS and snapshot them.
