After playing a few rounds in PvE mode, I experience that I have unstable connection to the server. My latency is constantly over 150 to sometimes 200ms with constant packet loss. 


Before i played PvE Coop i played the campaign with no problems. 


The one who i played the campagin is a friend who is living the in the same city (Berlin) and he does not a have this problem.


I have reset my network in Windows and my firewall. I have checked the game integrity (Steam client) and reset the graphics setting to default. I have disabled the crossplatform feature. I rebootet my router and got a new WAN IP. None of this was successful.
