We don't need to upgrade our graphics card I use a GeForce 8800GT 512mb which can run graphics heavy games like GTA IV, Fallout 3, Crysis, Assassin's Creed etc on max settings without lag. It's NOT a graphics card problem and if it was, how come even with crowd on there is no lag at night time matches??? The problem is either with the sound (Like Activision's Prototype which needed the removal of a sound file ambient.p3d to remove lagging) or something else with the game coding.
