What eDPI means

eDPI (effective dots per inch) puts your whole mouse setup into one number: how fast your crosshair really moves, however you split it between mouse DPI and in-game sensitivity.

in-game sensitivity×mouse DPI=eDPI

That is why two players can feel the same on completely different settings: low sensitivity at high DPI and high sensitivity at low DPI can land on the same eDPI, and the same speed.

0.5 sens × 1600 DPI=800 eDPI=1.0 sens × 800 DPI

Because it folds everything into one figure, eDPI is how players share their settings and copy a pro's aim without quoting DPI and sensitivity separately.
