If "Enhance Pointer Precision" is enabled your cursor will move on a DYNAMIC Axis. Meaning the mouse will function at the DPI you set it to by default and as you raise or lower the speed of the mouse the cursor will accelerate or decelerate dynamically on a multiplier. The faster you move your wrist/hand the more the speed of the cursor will multiply. This will increase mobility but decrease linearity and consistency of your accuracy without proper training. We STRONGLY recommend disciplining your senses with this setting "Unchecked" and after adapting completely, re-enable this setting to learn the differences precisely. This can affect you greatly if you're trying to land snapshots/shots taken during fast mouse movement. There will be mathematical inconsistencies.

If "Enhance Pointer Precision" is disabled/unchecked your cursor will always move at the DPI you set your mouse to on a linear axis and will never decrease in speed or increase in speed based on movement. Your mouse will not accelerate in high speed maneuvers such as performing 180's around a corner, but you have a dead accurate experience using your mouse. I recommend this as the best way to play if you have any issues landing your shots or with shot timing or if you simply want the most accurate experience.
