Proxmox shows very low resource usage on an LXC Container

[Metteus]

Hello,

My proxmox host version 6.0-6, shows incorrect RAM and CPU values (too low). This happens for ONE LXC container only.
The problem started after i pass through the quicksync/GPU to enable the hardware transcoding feature in plex.

Is this contradictory to (h)top inside the container?

Yes it was contradictory, but now the problem has gone. It shows correct values. I don’t remember what I did but I suppose an update and then a reboot.
