Understanding Pro CS2 Settings
What is eDPI?
eDPI stands for Effective Dots Per Inch. It is calculated by multiplying a player's in-game sensitivity by their mouse DPI. Because players use different hardware DPIs (e.g. 400 vs 800), looking at their in-game sensitivity alone tells you nothing. eDPI is the only true way to compare how fast two players' crosshairs actually move.
Calculate your eDPI ➔Why do most pros use 400 DPI?
Historically, older mice sensors performed best at 400 DPI natively. While modern sensors are flawless at 800, 1600, or even 4000 DPI, many veteran CS pros stick to 400 DPI purely out of habit and comfort in Windows menus. Today, an increasing number of young prodigies are adopting 800+ DPI for slightly lower input latency.
