I could be wrong but I think you can only pass through an entire GPU as long as it's unused on the host. Sharing a used GPU, in the same way we can share a CPU

Sharing a used GPU, in the same way we can share a CPU with no performance loss via Intel Hyper v, is not possible.
- RamRodification 5y agoYeah, just edited my post with that point. I think you're right.
- funcDropShadow 5y agoSharing a CPU with no performance loss isn't possible either. The amount of CPU loss varies dramatically by the exact virtualisation stack used and by the application running on top of it, but it is very clearly observable.
- apatheticonion 5y agoAre you sure? I am not sure if Geekbench is a valid benchmark but I have an AMD 5900x. Running it in Windows (host) I have a lower score than I get in VMWare running Ubuntu (guest).
- joveian 5y agoIntel GPUs can be shared, it is called GVT-g (expensive AMD and nVidia have similar abilities). It isn't trivial to set up at this point but it sounds like it works.
