Ever wondered why your mouse just doesn't go where you want it to be?
this is because of "mouse acceleration" and for fps gamers is the root of all evil
using a gaming mouse while this "mouse acceleration" is enabled defeats the purpose of a gaming mouse
now for all those who doesn't know how to disable it its very simple
simply go to the control panel and double click on the mouse icon
now in the mouse options go to the "pointer options" tab and uncheck enhance pointer precision(by default this is checked in winXP)
and that's it! simple right?
also note that this will not fully remove mouse acceleration but greatly reduces it
How to fully remove mouse acceleration
[for WinXP only]
download "CPLmouse fix"
this will edit your registry to disable any mouse acceleration left
there are two files one to install and the other to uninstall
restart the computer to apply changes

It's a mouse fix that professional gamers use for accurate mouse sensitivity.
One of the Cyberathlete Professional League's members' have made this simple
registry change that will disable any mouse acceleration made by Windows XP.
Be warned: it will feel awkward and slow at first. This is true. By removing
acceleration, your mouse pointer, (crosshair perhaps), will accurately display
the movement that you make on your mouse. Therefore, making a very-sensitive mouse
movement. It may not have any effects out-of-game, but it is very noticeable ingame.
[Vista/win7]
there is currently no way to fully disable mouse acceleration in win7 and vista Angry
but there is a way to reduce it to an almost unnoticeable level.
