How Many FPS Can the Human Eye See?

How many FPS can the human eye see? That’s a tough question because the human eye doesn’t really see in “frames per second,” and everyone’s eyes are different. We’ll talk about the biology, but the real question is what the upper limit is when it comes to FPS on monitors. At what point do you stop noticing FPS increases?

The Highest FPS That Humans Can See How Human Eyes Perceive Light Can Human Eyes See Above 90Hz? Is it Worth It to Get a 144Hz or 240Hz Monitor?

First and foremost, humans do not see in frames per second (FPS); FPS is how a monitor displays images. When we see these images, our eyes are absorbing the light, and our brains make sense of what we’re seeing. We mentally combine multiple quickly-displayed images and interpret them as continuous motion.

Let’s use Hertz (Hz) as the unit of measure to discuss this topic. 1Hz is one cycle per second. Although 1Hz and 1 FPS both use one second of time, they are not exactly equivalent. Hertz measures your monitor’s refresh rate, and FPS is how many frames the GPU of your device (like a console) puts out per second.

In a study conducted to test the limits of human eyes, researchers found that the exact cycles per second that people can visually track vary a lot. A maximum of 60Hz to 90Hz is often reported, but under the right conditions, the test subjects were able to perceive things at up to 500Hz. However, this was under specific conditions and does not emulate what it’s like when you’re gaming or watching a movie.

Next, let’s briefly look at how monitors display images. The light produced from artificial sources is not as consistent as it seems. The display of monitors—despite seeming consistent—is actually multiple cycles of light being produced at a fast enough
