GPU Passthrough | Proxmox Support Forum
forum.proxmox.com › threads › gpu-passthroughMay 24, 2019 · Hey everyone, this is my first go at setting up Proxmox. I have an Ubuntu 18.04 VM running on an older HP Z400 with an upgraded AMD FirePro v4800 GPU. I setup the GPU passthrough as described by the docs and lots of googling. I was able to get Ubuntu to see the GPU but performance is awful, it can barley paint the UI, lagging on everything.
