Quick answer
What is the Frame Rate Test?
A frame rate test shows the same motion at different frames per second (FPS) side by side: 15, 24, 30, 60 and your screen’s maximum. It makes the difference between choppy and smooth motion visible and shows why 24 FPS films and 60 FPS games feel so different.
Key features
- Five lanes at 15, 24, 30, 60 FPS and max
- Adjustable speed to exaggerate or soften motion
- Shows your measured maximum refresh rate
- Pause and fullscreen controls
Why use it
- See what a high-refresh monitor adds
- Explain FPS to students or viewers
- Runs on any modern browser

About the Frame Rate Test
See the difference frame rate makes. Five lanes move the same object at the same speed, but update it at 15, 24, 30 and 60 frames per second, and at your display's full rate. Lower frame rates look steppier, and the top lane shows the smoothest motion your screen can show. Raise the speed to make the difference obvious. Measure your screen's rate with the Refresh Rate Test.
How to use the Frame Rate Test
Watch each lane; they all move at the same speed.
Raise the speed to make stuttering easier to see.
Compare the 60 FPS lane with the max lane on a high-refresh display.
Press F or double-tap the screen to go fullscreen, and Esc to exit.

Frequently asked questions
Why does the max lane look like 60 FPS?
Your display shows at most one frame per refresh. On a 60 Hz screen the 60 FPS and max lanes look the same.
Why does 24 FPS look jerky here but fine in films?
Film cameras record motion blur within each frame, which smooths movement. This test uses sharp frames, so every step is visible.
What frame rate do I need for gaming?
At least 60 FPS feels smooth for most games; competitive players aim to match a 144 Hz or higher monitor.
