PSA Method Calculator
Find your perfect FPS mouse sensitivity in 7 rounds
PSA Method Calculator is a free, browser-based tool that helps FPS gamers find their ideal mouse sensitivity using a binary search algorithm. Users enter their current in-game sensitivity and choose between lower and higher values over 7 rounds, progressively narrowing down to a personalized recommendation. It works across popular FPS titles like Valorant, CS2, Apex Legends, and Overwatch 2 with no sign-up required.
The tool runs a 7-round binary search starting from the user's current sensitivity, presenting lower and higher candidates each round until the range converges to within ~5% of the user's preferred value.
