Proxmox GPU passthrough issue with WDDM

Hi,

Currently working on a issue that I haven’t come accross yet in these topics.
We are working on a system for customers with Proxmox and a Windows 10 VM.

Current setup is with a Nvidia Quadro P620. We noticed that the GPU was recognized in the Windows VM, but didn’t show up in the taskmanager.

After some research, we where made aware that the WDDM version on the VM is set to 1.3 and needs to be at least 2.0 in order for it to work.

Does Anyone have any idea how to get this done?
Passthrough isn’t really detected and measurable this way for testing purposes.
Looking forward to getting this resolved.

Kind regards,

J.
