Your ping is going to affect the amount of data that you recieve from the server you are playing. So if you have a high ping you are going to get less information and everything is going to be very choppy. The models are jump around instead of moving smoothly. It makes it harder to aim at your target because there is a bit of delay. To compensate you can lead your target a bit (aim a bit in front of where your target is moving instead of where you see him). There is not a whole lot you can do to improve your ping other than increasing the speed of your internet connection. Make sure that you shut down any programs that are running in the background that might be using part of your bandwidth.
