I have a server with a Nvidia 2060 RTX, which I have split into two machines, by following this guide: https://gitlab.com/polloloco/vgpu-proxmox
One of the machines is a Windows 11 Pro, which I am using as a Cloud Gaming computer. It works fine when the machine has just been booted. Everything is running fine and smooth for the first 20 minutes. Then the performance will drop, and I only get a max of 15 fps. If I reboot the machine, it will work fine again for another 20 minutes.
If I run the driver installation for the GPU in the VM, it will also work for 20 min after (same as if I made a reboot).

I have tried with both the "Guest drivers" in the package from Nvidia (Provided from the "licenses nvidia" page) as well as the newest drivers from there website. But still have the same behaviour. The 20 min until the frame drops is consistent as you can almost set your watch for it.
Anyone who has a clue what is the reason for this? Or maybe what I need to do to find out that the issue is?
