ℹ️ About FPS Test

FPS (Frames Per Second) measures how many frames your browser renders per second. This tool uses the requestAnimationFrame API for precise real-time measurement.

FPS Reference

• 144+ FPS: Esports-level smoothness (requires 144Hz+ display)

• 60 FPS: Standard smooth experience (60Hz display)

• 30 FPS: Barely usable, slight stutter

• <30 FPS: Noticeably laggy, optimization recommended

❓ FAQ

What is FPS?

FPS (Frames Per Second) indicates how many frames your display/browser renders per second. 60FPS is the smooth standard, 120FPS/144FPS is high refresh rate, below 30FPS feels laggy.

Is this FPS test accurate?

Uses the browser requestAnimationFrame API for precise measurement with minimal error. Results reflect the actual rendering frame rate of the current browser tab.

Why is my FPS capped at 60?

Browsers sync animation frame rate to display refresh rate by default. 60Hz displays cap FPS at 60. High refresh rate displays (120Hz/144Hz/240Hz) can show higher FPS.

How to improve FPS?

Close other tabs, disable browser extensions, use high-performance mode, ensure GPU drivers are updated, use a high refresh rate display.
