CS2 Mouse Sensitivity and eDPI

There is no correct sensitivity, but there is a range almost every good player lives inside — and a habit that stops more players improving than any number ever could.

What eDPI is

eDPI is your mouse DPI multiplied by your in-game sensitivity. It is the only number worth comparing between players, because 400 DPI at 2.0 and 800 DPI at 1.0 are the same physical movement.

400 DPI x 2.0 sens = 800 eDPI

The range that works

Most Counter-Strike 2 professionals sit between roughly 700 and 1,000 eDPI, which works out at somewhere around 25 to 40 centimetres of mousepad for a full 360-degree turn. That is much lower than most newer players run, and it is low for a reason: at that speed the small corrections that decide a duel are made with the arm rather than flicked with the wrist.

Testing whether yours is too high

• Aim at a head-height wall mark. If your crosshair regularly overshoots and has to come back, sensitivity is too high.
• Try to hold a spray on a single spot at ten metres. If the pattern wanders sideways, your hand cannot make corrections that small.
• Check how far your hand travels for a 180. If it is a wrist flick, you have no room left for precision.
• Watch where your mouse ends up after a fight. Constantly re-centring means you are fighting the pad, not the opponent.

The real mistake

Changing sensitivity is what stops most players improving. Aim is muscle memory, and muscle memory needs a constant to build on. A mediocre sensitivity kept for six months beats a perfect one changed every fortnight, every single time.

Pick something in the range above, write it down, and do not touch it again until you have played a hundred matches. If it still feels wrong then, change it once — by a small amount — and commit again.

Windows and acceleration

Keep Windows pointer speed at the sixth notch, which is 1:1, and turn off Enhance Pointer Precision. Turn off any acceleration in your mouse software as well. Acceleration means the same hand movement produces different in-game distances depending on speed, which is precisely what muscle memory cannot work with.
