This utility is a high-performance diagnostic node optimized for modern browser environments. All data processing is evaluated locally without requiring heavy external plugins.

Sub-Millisecond Accuracy: Utilizes the native requestAnimationFrame API to chart exact screen paints.
Synthetic Load Testing: Intentionally inject heavy DOM nodes to see how your hardware handles intensive web apps.
Continuous Tracking Chart: Interactive graph plotting your framerate over time.
Zero Knowledge Extraction: All metrics are computed locally in your browser.

System FAQ

How do I check my FPS online without downloading software?

Simply open this page and the FPS counter will immediately start measuring your browser's frame rate using the requestAnimationFrame API. No downloads or installations required.

What is a good FPS for a browser?

For smooth web browsing, 60 FPS is the standard. Gaming monitors run at 144Hz or 240Hz, but web content typically targets 60 FPS. Below 30 FPS will feel noticeably sluggish.

Why does my FPS cap at 60 even though I have a 144Hz monitor?

Browsers synchronize their rendering loop with your monitor's refresh rate. To unlock higher FPS in your browser, make sure your OS display settings are set to 144Hz, not 60Hz.

What causes FPS drops in a browser?

Common causes include too many open tabs, browser extensions consuming CPU, outdated graphics drivers, background software, or pages with heavy JavaScript and animations.

Does this FPS test affect my whole computer?

No. The load test is isolated to the browser tab. It stresses the browser's render engine to measure performance drops, but it won't affect other applications.
