The eye is one of the most important organs for relate to the outside world. Therefore, the often repeated question of how many FPS the human eye sees is repeated many times. Biology enthusiasts or fans of technology and video games, everyone at some point may have asked this question.
The answer is not simple, because it depends on many aspects, but research and cases indicate that 24 FPS is the minimum we perceive to detect movement on screen. Subsequently, each individual has the ability to interpret a greater number of frames per second. What does this mean? Let's dive into the world of video games and multimedia content, to answer how many FPS the human eye sees.
Refresh rate and monitors
In the world of video games and multimedia content, technology has opted for monitors with a high refresh rate. This is because they are devices that will allow us to see hundreds of frames per second, without residual images.
An FPS is the unit with which the number of frames that a device generates or processes in 1 second is measured.. Video games and applications use this unit a lot, to be sold to the public as fluid and dynamic proposals. The more FPS, the more frames. In addition to the FPS, there are the refresh rates of the monitors that are measured in Hz (hertz). This indicates how many times the panel image is updated per second, this way we know how many different images the screen shows in that second.
How many FPS does the human eye see in video games?
The question about FPS and video games, and how it is perceived by our eyes, has become very repetitive due to technological advancement. Today many video games use engines capable of displaying more than 120 frames per second. This is recent, since in the past, enjoying a video game at 60 FPS was already a luxury.
Video game engines have been advancing, and today they have a great capacity. The creation process begins in the central processor of the CPU, then the graphics card renders and colors applying textures and filters. This process of creating frames has been evolving and notably improving the capabilities of computers and video game consoles. In the past, devices limited games to 30 or 60 FPS, because resources were used for both frame rate and physics and other game features. Today, the power of each component helps deliver incredible gaming experiences that can be reflected in titles running at 120 FPS.
In theory, we could even have infinite FPS. But this requires monitors with high refresh rates to be able to display that number of frames and not be left with residual images between one change and another. When the FPS is fluid, what we see on the screen is a smooth and natural transition. But how does our organic component influence here? The human eye.
The limits of the organism
The human eye begins to perceive movement, and not a succession of static images, starting at 24 FPS. As we said at the beginning of the note, this is the minimum that our brain and our eyes require to do the entire reading process that ends up reflecting the movement. But there are people who have a greater capacity for perception, which will allow them to see the change between one frame and another with greater detail and fluidity, and those who will perceive it less.
The shooters, or shooters, are fast-moving titles where high frame rates are more apparent. A high refresh rate helps, in these games, a much more logical fluidity and naturalness in the game. If we had a low refresh rate, we would perceive the movements in a rough way.
The brain and its importance to understand how many FPS the human eye sees
The eye is the organ that receives the external stimulus, but "vision" is a process of interpretation What does our brain do? Light enters our eyes constantly and our two eyes work by sending different signals to the brain to convert it into depth effects and the information we perceive. The eye sees movement and how light is refracted in different elements of the world, and our brain interprets it with the conscious and unconscious.
This process takes a while, and although a maximum speed has not been determined, we know that from 24 FPS a sensation of movement is already achieved. Then, the physical capacity will be what determines which people have the greatest capacity to perceive these movements. As the frame rate per second increases, fast motion will become more fluid, dynamic and noticeable. Otherwise, we will see jumps, stumbles and abrupt transitions.
