Mouse acceleration was originally used because older mice were not accurate enough to be used without it, but any modern gaming mouse is good enough that you do not need to use mouse acceleration. If you do not use mouse acceleration there are no limits to your speed and accuracy. With mouse acceleration on you have to move the mouse below a certain speed threshold to obtain pixel perfect accuracy which puts an artificial limit on how fast you can make precise movements. With proper mouse settings and no mouse acceleration you can hit any pixel on the screen near instantaneously, only limited by your physical dexterity. Mouse acceleration is bad because it limits the speed you can make precise movements. For example, if you move your mouse 1 inch very slowly your cursor will only move an eighth of an inch, and if you move your mouse 1 inch but very quickly your cursor will move 10 inches on screen. With mouse acceleration enabled the distance your mouse cursor moves also depends on how fast you move your mouse. This consistency is extremely important in games. For example, if you move your mouse 1 inch your cursor will move 1 inch on your screen, and if you move your mouse 10 inches your cursor will move 10 inches on your screen. Without mouse acceleration your mouse cursor will move an exact distance for every inch you move your mouse. Mouse acceleration is generally bad for gaming. Enhance pointer precision is Windows' term for mouse acceleration. This is typically enabled by default so most people have it enabled.

The next and most important thing you need to do is uncheck Enhance Pointer Precision. If you want to adjust your pointer speed and retain 100% accuracy you need to change your mouse DPI instead. For 100% mouse accuracy you need to keep the pointer speed set at 6/11. The default pointer speed setting is right in the middle on the 6th notch (there are 11 notches). Go to the Pointer Options tab at the top then take a look at the Motion category. The mouse property settings are located in the control panel. The first thing you should do when setting up your mouse is change your Windows mouse settings. Follow this guide and you will become a 1337 360 no-scope headshot master. Bad mouse settings can hold you back from unlocking your true potential. Mice and mice settings are extremely important when it comes to gaming.
