What Fps Does The Human Eye See? – The Complete Guide
When it comes to gaming, you might have heard the term ‘frames per second’ or FPS. FPS is a metric used to measure the number of frames being displayed on a screen per second. In gaming, a higher FPS is considered better, as it makes the game feel smoother and more responsive. But what FPS does the human eye actually see? Let’s explore.
Understanding the Human Eye
To understand what FPS the human eye sees, we need to understand how the human eye processes visual information. The human eye is a complex organ that can detect changes in light and color. The human eye can perceive up to 10 million different colors, and it can also detect changes in light as small as 1/100th of a percent.
The human eye sees the world through two different types of cells called rods and cones. Rods are more sensitive to light and allow us to see in low light conditions. Cones, on the other hand, are responsible for color vision and allow us to see details and sharpness.
When we see an object, the image is processed in the brain, which interprets the data received from the eyes. The brain then integrates this information with other sensory input to create a complete picture of the world around us.
What FPS do we need?
Now that we understand how the human eye processes visual information let’s talk about FPS. The average human can process information in as little as 13 milliseconds, which translates to around 75 frames per second.
However, this number can vary depending on factors such as age, health, and individual perception. Research has shown that people can detect changes in visual stimuli at a rate of up to 500 frames per second.
So, what FPS do we need to perceive motion? The answer to this question depends on the type of motion being observed. For slow-moving objects such as a snail crawling, we may need as little as 10 frames per second to perceive motion. However, for faster-moving objects such as a car moving at high speed, we may need up to 60 frames per second to perceive motion.
In gaming, the recommended FPS is typically between 60 to 120 frames per second. The higher the FPS, the smoother the game feels, and the more responsive the controls.
Factors that affect our perception
Several factors can affect our perception of FPS. These include the lighting conditions, screen size and resolution, and the type of motion being observed. Here are some key factors to keep in mind:
Screen size and resolution – A larger screen with a higher resolution will require more FPS to achieve a smooth and responsive gameplay experience.
Motion blur – Motion blur can help make lower FPS games appear smoother by creating a blurred image between the frames. However, it can also make the game feel less responsive, leading to some input lag.
Refresh rate – The refresh rate of a monitor is a significant factor in the perceived smoothness of a game. A higher refresh rate monitor can display more frames per second, leading to a smoother and more responsive experience.
Lighting conditions – Brighter environments can improve our ability to perceive motion, while darker environments can make it more difficult to perceive motion accurately.
Final thoughts
In conclusion, the human eye can perceive motion at a rate of up to 500 frames per second, but we typically need between 10 to 60 frames per second to perceive motion, depending on the speed of the movement. While a higher FPS in gaming is usually considered better, there are several factors that can affect our perception of FPS, such as screen size and resolution, motion blur, refresh rate and lighting conditions.
