If using Windows in a VM, do a clean install, otherwise it'll run like shit. Either that or something was updated that improved the Virtio speeds. Before the clean install the scores were less then SATA. The disk had way more shit on it though.

Now to play Far Cry 5 on the PS4.

To change the drive to Virtio in a VM, after installing to SATA, change an additional drive to Virtio, and install the driver, shut down, and change the main drive to Virtio. If you already did that in the past, but changed the drive back to SATA, and booted it, you have to change the additional drive to Virtio and boot, then shut down, and change the main drive to Virtio. If you don't, then Windows will just reboot itself while booting.
