Windows 11 VM freezes randomly when PCI passthrough

Hi there -


It's been weeks already me trying to debug the situation. I have a Windows 11 VM as my daily driver which randomly freezes (mostly when unused). When this happens I can see the assigned CPU cores are maxing out in the Unraid dashboard. 


I have tried different configurations and it seems that this behavior only occurs when passing through my RTX3070 GPU. I have observed that without passing through the GPU and any PCI or USB device the system works fine. 


I really have no idea what to look next. Any advise is greatly appreciated.

Thanks for the feedback. I tried it myself with 6.12.6 and it works indeed. However, I can see increase in CPU usage and drops my FPS significantly during gaming. Regardless if I load my games from that particular disk or not. WinFSP and VirtioFS were also disabled in some of the tests.
