PSA Calculator
Find your FPS mouse sensitivity with PSA Method
PSA Calculator is a free browser tool that helps FPS players find a practical mouse sensitivity using the Perfect Sensitivity Approximation method. Start with your current sensitivity, compare lower vs. higher values, and narrow it round by round.
Hey Product Hunt 👋
I built PSA Calculator as a small, focused tool for FPS players who want a more structured way to find their mouse sensitivity.
Instead of guessing a “perfect” number, the tool walks you through the PSA Method:
• Start with your current in-game sensitivity
• Compare a lower and a higher value each round
• Choose the one that feels more controllable
• Repeat until you get a practical sensitivity baseline
It currently works well for games like Valorant, CS2, Apex Legends, Overwatch 2, Fortnite, and other shooters where you can manually adjust mouse sensitivity.
Why I built it:
Most sensitivity tools either convert values between games or calculate eDPI. Those are useful, but they do not help when a player simply asks: “What sensitivity actually feels right for me?”
PSA Calculator is meant to answer that with a repeatable test flow.
I’d love feedback from FPS players, aim trainers, and anyone who has struggled with sensitivity settings:
What would make this more useful for your own setup?
