Description
PSA Method is a free online tool for FPS players who want to find a more comfortable and repeatable mouse sensitivity. Instead of copying another player’s settings or guessing manually, users enter their current in-game sensitivity and complete 7 guided rounds comparing lower and higher values. The calculator narrows the range step by step and gives a final sensitivity recommendation based on the player’s own aiming feel.The site also includes practical guides and a reaction time test for players who want to warm up, compare input consistency, and better understand their aiming setup. It works directly in the browser with no signup, download, or account required.
