Because of the time it takes for the server to communicate with the client, and the time it takes for the server to compute things the hitbox as seen on your screen will not be at the same position as on the server. Here are some videos showing this effect for shootmania from before the update and from CS:GO:whizz wrote:Hi,

These movies where created by combining both the client side and the server side replays of a match.
If the game would use a very detailed hitbox, then this effect would be very huge and the hitbox would only work properly if each player stood still. For a game as shootmania where movement is fast and aiming precise this effect needs to be as small as possible, this is achieved by using very simple hitboxes.
