Ideal FPS Sensitivity Finder
Find your personalized, anatomically perfect sensitivity using the PSA (Perfect Sensitivity Approximation) binary search method. Test high vs low sensitivities in 7 quick rounds to discover your ultimate aim settings.
📖 How to Measure & Find Your Ideal Sensitivity
Enter Base Specs
Select your main game (e.g., Valorant or CS2), enter your starting in-game sensitivity, and select your mouse DPI (e.g., 800 DPI).
Compare Option A vs B
In each of the 7 rounds, test Option A (Low Sens) vs Option B (High Sens) on the interactive target arena below or in-game, then click which felt smoother.
Get Ideal & Converted Sens
After 7 rounds, receive your exact mathematical Ideal Sensitivity, eDPI, 360° turn distance, and converted values for all major FPS games!
🎯 Step 1: Base Settings Setup
Enter your current game and starting sensitivity to initialize the 7-round PSA binary search algorithm.
What is the PSA Method (Perfect Sensitivity Approximation)?
The PSA (Perfect Sensitivity Approximation) Method is a systematic binary search algorithm developed by professional FPS esports coaches to determine a player's anatomically ideal mouse sensitivity.
Starting from your base sensitivity, the algorithm generates a Low Sens (Base × 0.5) and a High Sens (Base × 1.5). By testing both and picking which feels smoother, the algorithm narrows down your range in 7 binary rounds to find your exact optimal sensitivity point.
Tactical shooters like Valorant and CS2 generally benefit from lower sensitivity (25cm–45cm per 360°) for micro-precision headshots. Fast tracking shooters like Apex Legends and Overwatch 2 often benefit from medium sensitivity (20cm–35cm per 360°).
