I have this problem at my friends house, I dont have this problem at home, you need a better internet connection.
I have the fastest connection available in my area (a major city) and it works just fine for EVERYTHING else I do with it, including playing other games. I see the same stupid response in every lag topic and none of you seem to learn from the respOnses you get for it.
CoD is NOT a complex multiplayer game compared to others I play, so tell me why it's the only game my connection isn't god enough for.
You really should ignore any ignoramus who blames a person's "poor" internet. It's obvious they're clueless. On topic, Treyarch should have been removed a long time ago. It's obvious that even with the foundation being spoonfed to them, they have no idea what they are doing....
