I noticed this yesterday... I have a Windows 10 VM, headless but I have a GTX 1660 passed through it. Works fine. I RDP into and check the CPU usage, normal. Once I disconnect though, one of my threads jumps to 100 and stays pegged... once I reconnect though it goes back down... I've restarted the VM, tried it again, still does it after I disconnect. What's going on? HTOP from unRaid WebUI console just shows the VM using CPU but that's it.. UnRaid 6.6.7.
EDIT 0--- If I restart the VM And don't remote in, the CPU Usage stays low and "normal" levels.
