I have a windows VM that is used for playback of youtube and plex and it drops frames and audio gets out of sync. I would like to resolve this if I can. I am wondering if there is a tweak, or a driver for windows that is necessary?
VM is stored on an a ssd. AMD RX580 GPU is pci passthrough connected to a 1080@60 monitor vis hdmi.
CPU is i5-8400 and 6 cores are assigned to this vm. Windows reports this is as 2.81GHz but proxmox shows running at 3800MHz when monitoring with
In windows, cpu and gpu utilisation never shows above 30%. I ran geekbench and it seemed to give a result expected of this cpu.
any advice on tweaks that might improve the experience?
