I was playing about a week ago, when MW3 was version 1.4 something, doing just fine with gameplay and connection. Thought I was playing pretty well for my standards. I get 8 mb down and barely 0.5 mb up where I live at the moment, and I get into <75 ms ping  games (I still do after this update 1.5). I read somewhere in these forums or in fact saw it somewhere, that Robert Bowling said Lag compensation will be a thing of the past. It was, and now it seems to me it has returned, and is again present just like when the game first game came out, because the gameplay is now poor, and I all of sudden suck at this game. The update is now 1.5.498.12. Either this is a Robert Bowling fail, or people are cheating. I say that because I've recorded some footage, where I'm getting one shotted full health, with an assault rifle.
