Than thats your problem. Consoles are pretty weak in the numbers area, as I recall ps3 and 360 only get 24 players, whilst pc gets 64. Consoles are so poo haha.
But seriously, it was made as a PC game, and the console part was tacked on, hence the poor graphics, awful frame rate, less than half the player count. THey should have left it PC only really, kept warfighter as the CoD alternative.
