Hi,
I'm having a similar issue with my Windows 11 VM (very very laggy, 100% assigned CPU just by opening a web browser). Did you figure it out ?
I tried the nvidia-smi command, but it gives me an error:
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
It may be because I bound my GPU to VFIO, I don't know.
