DXGI_ERROR_DEVICE_HUNG in Windows 11 VM with gpu passthrough

[jeroslav]

Hello,
I have successfully passed my RTX 2070 to a Windows VM, with the help of Proxmox documentation. Thanks for that. I am getting an error DXGI_ERROR_DEVICE_HUNG in various times of game play - sometimes in 5 minutes, other times in 20 minutes. I have looked through almost all the suggested solutions - removed drivers with DDU, modified registers, run Furmark to test stability of GPU. No signs of issues.
My specs are low-end but I don't think it should be an issue:
Ryzen 3 2200G
16GB RAM
RTX2070

Windows VM config:

Apart from the Windows VM I only have a small VM for Home assistant, etc.

Any ideas where I should look, what settings should I change for the VM?

Not sure how you are convinced of this.

This problem appears pretty widespread amongst Windows users. How do you know it is HV/VM specific?

Have you run this same setup bare-metal Windows without incident?

If not, what I would try - to test - is run the same HW bare-metal Windows & see if this persists. So maybe write the VM's virtual disk to a spare HDD etc. boot up from it - (you will have to probably go through various Windows reconfig/setup/tweaks) - & test.

Side note: I would change in the VM, the memory from 10000 to 10240 to give it a perfect 10GB - some OSs don't like those incomplete RAM amounts.
