What Is Your Browser's FPS?

Click Start to begin monitoring your frame rate. This tool uses requestAnimationFrame to measure real-time FPS and displays a live graph of your browser's rendering performance.

This tool measures your browser's rendering frame rate by timing requestAnimationFrame callbacks and displaying FPS with a live graph.

60 FPS is the standard for smooth browsing (16.7 ms per frame); high-refresh displays can reach 120–240 FPS.

What Do Your Results Mean?

Result Range Meaning
Good 55+ FPS sustained Smooth rendering performance. Animations and scrolling will feel fluid.
Warning 30–54 FPS Noticeable stutter during animations. Close heavy tabs or check GPU driver settings.
Bad Below 30 FPS Choppy rendering. Common causes include GPU driver issues, power saving mode, or excessive DOM complexity.

Common Issues and How to Fix Them

FPS stays at 60 even on a 144 Hz display

Most browsers cap at the display refresh rate. Ensure your OS display settings are set to 144 Hz and hardware acceleration is enabled in the browser.

FPS drops when other tabs are open

Browsers throttle background tabs. Close unused tabs and extensions. On laptops, plug in the charger to avoid power-saving GPU throttling.

Frequently Asked Questions

What does FPS mean?

FPS stands for Frames Per Second — how many times your browser can render a new frame each second. Higher FPS means smoother animations and scrolling.

What is a good FPS value?

60 FPS is the standard for smooth browsing. 120+ FPS is possible on high-refresh displays. Below 30 FPS may feel choppy.

Why is my FPS low?

Common causes: heavy page content, too many open tabs, GPU driver issues, power saving mode, or hardware limitations.

Does this test use my GPU?

Yes, the browser uses GPU acceleration for rendering. The FPS reflects your combined CPU+GPU rendering pipeline performance.
