Methodology & Precision Model

Calculation uses official Valve Source 2 engine constant: m_yaw = 0.022 degrees per pulse. Verified with raw input enabled.

* Measured with raw input without operating system acceleration.

2. Counter-Strike 2 Mouse Input Architecture

Counter-Strike 2 inherits the legendary Source engine input architecture. Mouse sensitivity directly multiplies raw hardware counts by the engine m_yaw constant (0.022 degrees per count).

Input Mechanics

CS2 uses raw linear input scaling. A sensitivity of 1.0 at 800 DPI yields 800 eDPI, requiring 51.95 cm (20.45 inches) of physical desk travel for a complete 360-degree rotation.

3. CS2 eDPI & Sensitivity Formula

In Counter-Strike 2, your effective sensitivity (eDPI) represents the true product of your hardware optical sensor resolution and in-game sensitivity slider:

CS2 eDPI = Mouse Hardware DPI × In-Game Sensitivity

For example, 800 DPI × 1 Sensitivity = 800 eDPI.

4. Physical 360° Turn Distance

Physical turn distance (measured in cm/360 or inches/360) is the ultimate metric for muscle memory synchronization. It calculates the exact mousepad width required to complete a full 360-degree rotation.

cm/360 = [ 360° ÷ (DPI × Sensitivity × 0.022) ] × 2.54
