Free PSA Method calculator. Find your perfect FPS mouse sensitivity in 7 rounds — works for Valorant, CS2, Apex Legends, Overwatch 2. No signup needed.
I built PSA Method Calculator because FPS sensitivity advice is usually either too vague or too copied from other players.
Instead of guessing a number, this tool guides you through 7 quick rounds: test a lower and higher sensitivity in-game, choose what feels better, and let the calculator narrow the range. The final value is based on your own aim feel, not someone else’s settings.
It’s free, browser-based, and made for players of CS2, Valorant, Apex, Overwatch, Fortnite, PUBG, and other FPS games. I’d love feedback from players who are tuning their sensitivity or helping friends find a more comfortable setup.
