How the Refresh Rate Test Works

This tool uses the browser's requestAnimationFrame API to count how many times your screen refreshes per second. Unlike a simple timer, this method is synchronized with your monitor's actual V-Sync signal, providing a highly accurate reading of your operating refresh rate.
