FPS & Refresh Rate Tester

Measure your browser's frame rate and stress test your device performance.

Current FPS

Average FPS

Refresh Rate

How to Use

  • 1.Close other tabs and apps for the most accurate result.
  • 2.Click Start Test. The counter typically locks to your monitor's refresh rate (e.g., 60 or 144).
  • 3.Stress Test: Click "+500 Objects" repeatedly. Watch the FPS drop as your GPU struggles to render thousands of particles.

Troubleshooting

  • Stuck at 60 FPS? Most browsers enforce "VSync" to save battery. If your monitor is 144Hz but you see 60, check your Windows Display Settings > Advanced Display settings.
  • Very Low FPS? Ensure "Hardware Acceleration" is enabled in your browser settings (Chrome/Edge/Firefox).
  • Inconsistent numbers? Background updates or video players can cause stutters.

FPS & Performance Guide

FPS vs. Refresh Rate (Hz)

FPS (Frames Per Second) is how many images your computer generates per second. Hz (Hertz) is how many images your monitor can display per second.
Example: If your PC generates 200 FPS but your monitor is 60Hz, you will only see 60 images per second.

Why is my 144Hz monitor showing 60 FPS?

This is a common issue. Follow these steps:

  1. Right-click your desktop > Display Settings.
  2. Scroll down to Advanced Display.
  3. Change the "Refresh Rate" dropdown from 60Hz to 144Hz (or higher).

Also, ensure you are using a DisplayPort cable, as older HDMI cables may limit you to 60Hz.

What is VSync?

Vertical Synchronization (VSync) locks your FPS to your monitor's refresh rate to prevent "screen tearing" (where the top half of the screen shows a different frame than the bottom). Browser-based tests usually have VSync forced on by the browser engine.

How to improve FPS?

  • Update Graphics Drivers (NVIDIA/AMD).
  • Close background apps (Chrome tabs, Discord).
  • Lower game resolution or graphical settings (Shadows/Anti-aliasing).
  • Ensure your laptop is plugged into power and set to "High Performance" mode.
