Occasionally, I rubber-band in certain games. But for the most part, I’m lag free from my point of view. However, when I go into theater, it turns I’m lagging pretty hard from other players’ perspective; as many hateful messages have pointed out. I don’t get it; What do I do? I don’t lag in any other game. I didn’t lag in the beta. I didn’t lag in the first month H5 released (Didn’t change anything regarding my internet). I don’t lag in Halo MCC. I DONT GET IT. 343, PLEASE HELP ME
