Physical Metrics & Math Formulas

When matching sensitivity across 3D engines, the most common mistake is comparing in-game slider values. The only scientific standard that delivers 100% physical muscle memory preservation is CM/360° (the physical centimeters the mouse must travel on a mousepad to rotate the camera exactly 360 degrees).

Absolute Displacement Equations:
CM/360 = (360 / (DPI * Sensitivity * Yaw)) * 2.54
Inches/360 = 360 / (DPI * Sensitivity * Yaw)
Where DPI is the hardware sampling rate, Sensitivity is the in-game value, and Yaw is the engine angular constant. X·ARENA aligns profiles using physical CM/360 to filter all resolution or FOV distortion.

Mainstream Game Engine Yaw Constants

Different game engines rotate the 3D camera by different angular amounts (Yaw constants) per mouse count. For instance, CS2 and Valorant handle raw mouse signals differently:

💡 Mathematical Proof: Why does CS2 sens 1.0 equal Valorant 0.3143? Because 0.022 / 0.07 = 0.3142857.... This is pure geometry, independent of monitor resolutions and scaling.

Focal Length & Monitor Distance Scaling Algorithms

When zooming in ADS or using sniper scopes, your FOV narrows and the image is magnified. Maintaining the same CM/360° physical distance makes the center crosshair feel uncontrollably fast because of the **non-linear projection distortion between 3D camera rotation and 2D flat monitor space**.

Monitor Distance & Focal Length Formula:
Zoom_Multiplier = (tan(Target_FOV / 2) / tan(Source_FOV / 2)) * (Target_Yaw / Source_Yaw)
Using the 0% Monitor Distance (MDV0) algorithm, the system aligns the tangential velocity at the absolute center. The mouse drag force required for a 1-pixel micro-flick remains perfectly consistent regardless of FOV changes (this is the built-in default match logic for both CS and Valorant).

Mouse Sensor Hardware DPI Deviation & Calibration

The "nominal DPI" set in your mouse software is an idealized target. In production, optical lens mounting tolerances, PCB thickness variations, and mousepad textures cause physical count discrepancies. Without measuring your "actual DPI", any mathematical conversion will still carry hardware-level deviation.

DPI Analyzer Calibration Formula:
Actual_DPI = Measured_Counts / (Physical_Distance_in_Inches)
Where Measured_Counts is the raw counts sent to the OS during a physical slide. For instance, if sliding 2 inches reports 1640 counts, your actual DPI is 820 (not 800). X·ARENA's DPI Analyzer measures this directly.

Academic References & Verification

The sensitivity formulas and FOV projection algorithms used in our lab are verified against official developer documentations and human motor control studies:

1. Valve Corporation — Source Engine SDK Reference Guide
Verification: The Source Engine explicitly defines m_yaw = 0.022 as the default degree-per-count value, cementing the identical physical scaling shared by CS2, Apex Legends, and Titanfall.
2. Epic Games / Riot Games — Unreal Engine Input Handling Documentation
Verification: Unreal Engine bases input on a default Yaw of 0.07. Riot Games aligned Valorant around this constant, mathematically establishing the 0.022 / 0.07 = 0.3143 ratio.
3. Journal of Human Motor Behavior — Visuomotor Adaptation in Virtual 3D Contexts (2021)
Verification: Visuomotor research shows that muscle memory under varied field-of-views matches angular velocity best near the center crosshair. This validates 0% Monitor Distance (MDV0) as the optimal matching method for flick-shots.
