Refresh Rate (Hz) is how many times per second your display redraws the screen (e.g., 60Hz/144Hz/240Hz/360Hz). Meanwhile, FPS (Frames Per Second) is the approximate number of frames your PC or browser can render per second. In practice, even with high FPS, if the display Hz is low, perceived smoothness will be limited. Conversely, high Hz with low FPS results in noticeable stuttering.

What This Test Measures (Approximate)

This page aggregates the frame rendering interval (Delta ms) and displays the average FPS as an approximation. However, the browser is strongly affected by OS, power saving, tab state, GPU load, VSync, etc., so this is not a precise measurement.
