I have everything configured and working properly for my VM and GPU passthrough. Everything works fine and games launch and run fine.
However, after a few minutes (it varies, 1-10 minutes) the client stops updating and my UPS drops to 0. Restarting the client, it fails to refresh at all and UPS stays at 0 (but shows FPS updates). This only occurs when I am actually running a game. I can leave it forever at the desktop and it never stops updating; however, running Mount & Blade: Bannerlord, it always stops updating after a random amount of time. After it stops updating, it requires me to restart looking-glass-host; its still running, I have to kill it and restart it.
I’ve disabled sleep and screensavers in the guest.
I currently have the guest GPU plugged into my monitor via HDMI, while I use it in my host via DisplayPort.
Is there an obvious step I’ve missed for this?
