Yes, when I said "some effort" that was what I meant, plus a fair amount of configuration, including isolating the card from Linux so it doesn't compete with the VM. Currently I don't see much prospect of full 3d video passthrough given that video cards are separate processors with (often) proprietary drivers that don't expect the video context to change arbitrarily under their feet and don't provide a way to snapshot their internal state (this applies to Windows too, even on bare metal, which severely limits hibernation when using GPU drivers). It's going to take a lot of industry effort (maybe via Vulkan, though I'm reaching here) for this to work in the future. poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
