Windows 10 VM - Code 43 on GeForce 650 Ti - Driver 472.98 WHQL - TrueNAS-SCALE-

When I create a Windows 10 VM, passthrough seems to work without issue, except for the GPU.

Device Manager:
After installing the driver (472.98 WHQL), the GPU shows up in device manager as if there are no problems. Sometime later (20-30 mins) I get Code 43. I can disable the device in device manager, then enable the device, and it stays listed without any issues…until I reboot the VM. Then the issue returns.

Task Manager:
The GPU is NOT listed in the performance section of Task Manager.

Right-clicking on the Desktop:
Nvidia control panel is not listed.

Other than Device Manager, there is no indication that the GPU present and\or doing work in the VM.

Host Specs (I am testing, this is not production):
Dell T630
(2) Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz
GeForce GTX 650 Ti

Host OS:
Note: TrueNAS-Scale is Debian and uses KVM for virtualization

Is any one else seeing this? Any suggestions?

I’m having the exact issues you’re describing on a GTX 660.
I’ve also tried the 471.96 driver with no luck.

If I find a solution I’ll try and keep you posted.
Have you had any further luck yourself?
