15 FPS vs. 30 FPS vs. 60 FPS

A Visual Comparison

I've heard a few people say "the human eye can't tell the difference between 30 and 60 frames per second." Well, they're right. But your brain can!

Here's my attempt to prove that you can detect the difference between 30 FPS and 60 FPS. Pay close attention to the way it "feels".

Note: "fps ok" means the animation is playing intended rate. If you see "fps too slow", it means your computer isn't rendering the animations fast enough.

Update: I've created an "HTML5"-based comparison here, in case you can't view the Flash animations below, or are just curious.

Let's start with 15 FPS. Kinda choppy...

Now, let's move onto 30 FPS. Much smoother...

Now 60 FPS.

I can easily detect a more life-like fluidity in the 60 FPS example.
