Avago (the manufacturer that produces sensors) measures and references in both CPI and DPI. Though It shouldn't really matter as you know what I'm referring to.Originally Posted by Rukumouru 
Dots per inch is actually incorrect: What the measure actually is is CPI (how many "counts" or "reports of movement to the PC" the mouse will make when it is moved one inch.)
What this means is, higher DPI (Actually CPI) has the mouse detecting its movement on a surface at a much higher precision.
High DPI + Lowering sensitivity to your tastes (sensitivity IS speed, CPI isn't) is the best result for 1:1 movement.

I made this so you guys know what I'm talking about.
BLACK LINE: IRL mouse movement
RED DOTS: Mouse "counts" (incorrectly referred to as DPI)
GREEN LINE: The path the mouse thinks it followed (as reported by its "DPI")
Left line would be "7 DPI", right line would be "5 DPI".
Why does the mouse move FASTER in the 7 DPI scenario? Because between every "report" the computer moves the cursor by a fixed amount (this is without Mouse Acceleration), and this amount is governed by sensitivity.
If the SENSITIVITY were tweaked in the left line as translasting to 1/7th of an inch between counts and 1/5th of an inch between counts for the right one, the end result would be the same amount of distance with a trajectory much closer to real life's in the left scenario.

Few things here:
- If you're referring to 3D, sensitivity isn't speed. It's a multiple of your mouse yaw and pitch angles.
- Precision isn't measured by your mouse DPI, but rather angle (yaw and pitch) and resolution size. (Again 3D) CPI serves as "speed".
- I'll agree that a lower angle allows for more "precision", though like above, Cranking CPI wont do anything in terms of helping.. It actually hurts worse.
- on 2D applications utilizing windows input. precision is only measured by the windows sensitivity bar. In which case a setting of 6/11 with EPP OFF is recommend. Going lower than 6/11 quarters and halves your sensitivity, though that isn't as bad as it seems. Just don't go above
