FPS Test · At a glance
Quick answer: Measure browser rendering FPS with an adjustable animated workload. Rendered FPS describes this animation.
FPS Test
The test loads when you open it. Device access is requested only after you choose to start.
Detailed guide
How to use this tool
- Start the browser animation, choose a workload and keep it unchanged between runs.
- Allow the cadence to settle before comparing results.
Input
Visible tab and animated workload
Browser requirement
requestAnimationFrame timestamps

How it works and what the result means
Frame cadence is estimated from requestAnimationFrame timestamps. Browser FPS may be capped by refresh rate, power settings or background throttling. It is not a native-game FPS prediction.
Reading the result
Rendered FPS describes this animation. A display-rate cap can make different GPUs return similar numbers on a light workload.
What to check next
Close other heavy tabs and check hardware acceleration. Use the same canvas, workload and power mode.
A frame sequence may reveal gaps in a camera photo, but software timing alone cannot prove a monitor is displaying or skipping physical frames.
Frequently asked questions
Will this predict FPS in a specific game?
No. Games use different engines, scenes, drivers and settings. This is a browser rendering check rather than a native-game benchmark.
How do I start the FPS Test?
Start the test and keep the tab visible. For FPS, adjust workload. For frame skipping, photograph the moving frame sequence with a long exposure.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
