No matter what I play online on the Xbox Series X, it keeps jerking and lagging.
However, there are never any full crashes.
The console is connected via LAN and all tests show:
Ping between 20-50ms
DL between 50Mbit-120Mbit
UL between 2Mbit-5Mbit
Packet losses can't be seen in the tests either.
I have an Easybox from Unitymedia. The problems only existed since the takeover of Vodafone. Of course you don't want to know anything about problems and you certify that I have perfect management.
Meanwhile it is extremely annoying when you have constant stutters and delays when playing.
I haven't noticed any similar problems with Wi-Fi and other devices, only with the Xbox Series S and previously with the Xbox One.
Some multiplayer games such as Apex, Battlefield or Rainbow Six Siege show the connection data, which could help to investigate the cause.
