How It Works
What is FPS?
Frames Per Second measures how many images your browser renders every second. Higher FPS means smoother animations and a more responsive experience.
What is Frame Time?
Frame time is how long it takes to render one single frame (in milliseconds). At 60 FPS the ideal frame time is ~16.6 ms. Lower is better.
What is 1% Low?
The 1% Low shows the worst 1% of recorded frames. A big gap between average FPS and 1% Low means your browser has occasional severe stutters.
What is Jitter?
Jitter is the variation in frame timing (standard deviation in ms). Low jitter means frames arrive at consistent intervals — important for smooth scrolling.
Stress Mode
Stress Mode adds an active particle renderer alongside measurement. Use it to test your browser under real visual load, similar to a game or heavy webpage.
Pro Tips
Close unused browser tabs, disable extensions, and try in different browsers to compare. Chrome, Firefox, and Edge often show different FPS results.
FPS Rating Reference
| FPS Range | Rating | Experience | Typical Use |
|---|---|---|---|
| 0 – 14 | Critical | Severe stuttering, nearly unusable | Browser issue / overloaded system |
| 15 – 29 | Poor | Visible lag, uncomfortable to use | Old hardware or heavy tab |
| 30 – 44 | Fair | Playable but noticeable drops | Acceptable for basic browsing |
| 45 – 59 | Good | Smooth for most tasks | Good for browsing & video |
| 60 – 89 | Great | Very smooth, responsive UI | Ideal for web apps & gaming |
| 90 – 144+ | Exceptional | Ultra-smooth, near instant response | High refresh rate monitor / gaming |
