Methodology & Precision Model

Uses standard Respawn Source engine constant: m_yaw = 0.022 degrees per count.

* Measured with raw input without operating system acceleration.

2. Apex Legends Mouse Input Architecture

Apex Legends utilizes the Source engine input pipeline, making its hipfire sensitivity values directly 1:1 interchangeable with Counter-Strike 2 and Team Fortress 2.

Input Mechanics

Apex Legends requires rapid 180° tracking and vertical target acquisition, leading most players to choose moderate sensitivity ranges between 30 cm and 45 cm per 360-degree rotation.

3. Apex eDPI & Sensitivity Formula

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

Apex eDPI = Mouse Hardware DPI × In-Game Sensitivity

For example, 800 DPI × 1.2 Sensitivity = 960 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

FAQ

Apex Legends FAQ

Common questions about mouse sensitivity and DPI in Apex Legends.

Is Apex Legends sensitivity the same as CS2?

Yes! Apex Legends and Counter-Strike 2 share the identical Source engine yaw constant of 0.022, so 1.2 sensitivity at 800 DPI is identical in both games.

What DPI is best for Apex Legends?

800 DPI or 1600 DPI is optimal for Apex Legends to balance fast camera rotation with smooth tracking over long distances.
