Dots per inch (DPI) is a measurement of how sensitive a mouse is. The higher a mouse’s DPI, the farther the cursor on your screen will move when you move the mouse. A mouse with a higher DPI setting detects and reacts to smaller movements.

Your Sensitivity can be found and changed by typing sensitivity into your CS:GO developer console:

TL;DR: basically, if you have your windows mouse settings at 6/11 and smoothing off raw input will not effect your sensitivity at all. What it will effect are "feel", which honestly might be a placebo. I recommend trying both and just using what you feel best from a blind test (have someone else change the settings for you and don't look at them)

Can be changed by typing m_rawinput "1" into your CS:GO developer console. 0 = off; 1 = on.

eDPI stands for Effective DPI. This number describes your "real" sensitivity.
