Technical Audit

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: Beautiful interactive graph plotting your framerate over recent history.

Zero Knowledge Extraction: All metrics are computed securely within your local sandbox.

System FAQ

Why does the FPS cap at my refresh rate?

Browsers synchronize their requestAnimationFrame loop with your physical monitor's refresh rate. If you have a 60Hz monitor, the maximum displayable FPS is 60.

Does the synthetic load test affect my whole computer?

No, the load is isolated to the current browser tab. The artificial DOM elements stress the browser's render engine, allowing you to gauge performance drops safely.
