I have been continually frustrated by the way controls work on the standard PS3 controller. There is aim assist, but in general the controller "makes you miss". The L3/R3 sticks are woefully inadequate as you basically over compensate whilst lining up your target. I have tried to fool around with the sensitivity settings but to no avail.
I have found playing COD on the PC a much better experience as you can aim much more accurately with a mouse and keyboard.
Is there an equivalent for playing COD on the PS3 ?
