bp lag

I will not return to the favorable opinions or not, everyone's tastes and expectations, I'm having fun, the game is beautiful, diverse modes short, what fun a while.
HOWEVER what I like least is the lag. I have a very good machine (i7 920 o / c + hd 5870 for a 22 inch screen) and my taste this game should not lagger much, especially not a call of duty (they have already enough opus behind them to know their toy) !!!!!!!!!!
Only hope a shift very quickly !!!!!!!!!

Regarding amazon: flawless. Command on Sunday afternoon, sent on Monday (day of the release of the game) and received Tuesday afternoon (along with a book ordered on the same day).
