COD servers be wildin sometimes. Doesn’t matter how good your net is. Packet loss is a silent killer too. You’ll be teleporting around and not even know why.
Could be background downloads or system updates messing with you. Check your task manager.
Crossplay lobbies can get messy depending on everyone’s connections. One bad ping ruins the squad.
High settings can spike lag too. Try dropping shadows and motion blur.
The lag hits hardest during events or new seasons. Everyone logs on at once.
