What is FPS? | Differences and Human Sight


A few months ago I was duly documenting this issue because I always saw opinions and many debates on this topic, where some say one thing and others say another, that is why I see it necessary to clarify all the doubts regarding the FPS so that people do not get confused.

What is FPS?

FPS is the frames per second that are displayed in a video, game or 3D application, the amount of FPS that your computer works will depend on several components of the same, more than all of your graphics card. Multi-component because your processor and RAM work together with your video card, and if they are much lower than your graphics card the FPS could be limited by the effect called a bottleneck. I say they could be limited because that will depend on the game or application that are running.

The lower FPS the images will be more choppy and higher but more fluid, so if you have low FPS in a game you will see everything choppy or frizzing, which indicates that your computer is not able to move that game correctly And you would need to change one or more of its components.

Differences and examples of FPS

The more FPS the more fluid the movements of the elements, in the following image you can see an example of how something would look different FPS:

Is it true that the human eye can see maximum at 30 FPS?

No, that is not true, the network is full of people who say and think that, that is one of the many fallacies that are invented on this topic. If that were true then limit all your games to 30 FPS so you see the great difference in the flow of the game or easier, look for a video gameplay type or Vlog on Youtube that is at 1080p60 and play it, then upload the same video to 1080p (Without the 60) and you will see a great difference in the fluidity of the movements because without the 60 the videos reproduce to 30 FPS or simply analyzing.

If the human eye can only see 30FPS  then why there is an option on YouTube that allows you to watch the videos at 60FPS?

And if this still does not convince you can enter this page (http://www.testufo.com/#test=framerates), in which you can put two objects to move together, one at 30FPS and another at 60FPS and you will notice a big difference. There is no reason to believe that the human eye sees a certain amount of FPS because the human eye does not work in FPS, it is almost the same as saying that the human eye sees x amount of pixels without first understanding that the human eye does not work that way.

What will it be based on to say that the human eye sees 25 images per second?

In short, the Internet is full of fallacies and people saying without knowing the subject, some even say so with security and technicality that he who does not know you believe.

Monitor FPS and Herz

Another important thing to know is that the FPS and Hz of the monitor go hand in hand because the FPS that is displayed on the monitor is limited to the amount of Hz of the monitor. If your monitor is 60Hz the monitor will transmit 60 FPS, even if the game you are using goes to 1000 FPS your monitor will only reflect 60 FPS if it is 60 Hz; if your monitor is 120 Hz the maximum amount of FPS that you will notice are 120 FPS. So having your game at 300 FPS with a 60 Hz, 75 Hz or 120 Hz monitor makes no sense, you would only sacrifice performance and power consumption of your graphics card unnecessarily.

So if you activate the vertical synchronisation the FPS will be limited to the amount of Hz of the monitor you are using because this adjusts the FPS according to the Herz of the monitor.
