Video Stream are hanging/buffering around every 10seconds

[Maximilian Krieglmeyer]

I am using KODI on Ubuntu and every Video stream I use is hanging after around 10 seconds. Ubuntu is setup on a Proxmox VM and the GPU is passed through. I tried to reinstall the driver without any effect. Network connection is a 50MBit/s line, so should not be the issue.
