Effective Dots Per Inch (eDPI) represents a unified sensitivity value in gaming, primarily first-person shooters. It is derived by multiplying a player’s in-game sensitivity setting by their mouse’s DPI (Dots Per Inch). For instance, if an individual uses a mouse DPI of 800 and an in-game sensitivity of 2.5, the resulting eDPI is 2000 (800 DPI x 2.5 Sensitivity = 2000 eDPI).
This calculated figure offers a standardized means of comparing and replicating mouse sensitivities across different games and hardware configurations. Its use facilitates sharing sensitivity settings between players and allows for a more consistent aiming experience, regardless of the specific DPI or sensitivity options available within a particular game. Historically, disparate sensitivity scales made comparing configurations difficult; eDPI addresses this problem by providing a common reference point.
