FPS Test – Check Your Screen Refresh Rate Online
Run this FPS test to see how many frames per second your browser can draw on your screen. Press Start and the page animates for 10 seconds while the tool records every frame, then reports your average FPS, lowest and highest FPS, the 1 percent low and a frame-time graph that shows stutter. It also estimates your display refresh rate, such as 60, 120 or 144 Hz. The result measures browser rendering on this screen, not the speed of a game or your graphics card, so use it to check smoothness and refresh rate.

Frequently asked questions
What does the FPS test measure?
It measures how many animation frames your browser draws per second while this page is in front. It reflects your display and browser, not a game or graphics card benchmark.
What is a good FPS result?
A result that matches your screen refresh rate, such as 60 on a 60 Hz screen, is ideal. Higher refresh rates such as 120 or 144 Hz look smoother.
What is the 1% low?
The 1% low is the average speed of your slowest 1 percent of frames. A big gap from the average means visible stutter.
Why is my FPS capped at 60?
Browsers draw in step with the screen. A 60 Hz display, power saving mode or a background tab can limit the result to 60 FPS or lower.
Why did my result drop?
Other tabs, battery saver mode and heavy background apps can slow the page. Close them and run the test again.
