Often, we see an option in the game settings that is to determine the field of view or FOV in a kind of percentage: if it is increased, we will have more peripheral vision, but if we reduce it we obtain the opposite effect. So, let's see what is the most recommended
The shooter's games are games where the field of view is important because the view of the player is in 1st person, so it is vital to control the sides of the screen. There are people who play with the FOV to the maximum, while others prefer to have it more limited because they "control" more what happens.
What is a field of view?
The field of vision is the range that a person can see through the eyes, but in video games, it can be artificially limited or expanded. You have to understand that everything begins in the eyes, the FOV (Field Of View) being composed of 2 :
Horizontal: it is usually about 200 degrees
Vertical: just over 130 degrees
Thus, in a virtual reality game (using VR glasses) we have a much wider and more enveloping FOV than when we play on a monitor. That said, not all VR glasses are the same - it depends on ergonomics, and bigger glasses are not always better (color distortions, chromatic aberration, etc.).
However, we can see how the video game settings allow us to widen or reduce the field of vision, is better? Well, humans have a FOV of about 200 degrees, but you have to understand that there is an effective FOV: we do not pay attention to all areas of our field of vision.
According to psychological studies, the human being tends to prioritize the center-right area, and for that reason, many preparers advise presenting our CV with the photo placed in the upper right area. Therefore, we process information in another at 40-60 degrees, leaving the remaining 160-140 degrees in our peripheral vision.
This is something that is well studied and what we usually process 100% is all the information that comes to us (through the center). For this reason, many times, there is an enemy on our right / left flank and we do not see it, but other spectators who are in our camera do (for example, in CS: GO).
So, having more FOV is not equivalent to " better ", but we will have more information about what is happening at our fingertips. Another very different thing is that we are able to process everything that happens in our peripheral vision.
The idea that must be borne in mind is to have an optimal field of vision for our needs because there will be games in which it is more useful to have a wider FOV, while in others the need will be the opposite.
How the FOV affects the video game?
We can say that there are 2 great genres in which FOV is super important: shooters or FPS and driving simulators. In driving or racing simulators it is important to have a wide FOV because we will benefit from a better sense of speed and a greater amount of information.
If we have a FOV with a few degrees, we will lose peripheral vision and sense of speed, which is horrible for the experience of a simulator: we do not have information about the dead spots (cars next to it).
On the other hand, if we have a very high FOV, it will appear that we are sitting behind the driver and we will not be able to see the cockpit well, as well as it will seem that we are going too fast. Hence, we say that it is important to adjust it to our needs.
What about the FPS?
It is important to have a field of view higher than the standard to be able to see enemies at certain points on the screen, moving the mouse only to aim and not to observe. If we use the mouse to observe because our FOV is limited, we will have less precision and a worse response time.
However, too high a FOV will make our weapon look small, the HUD too, and there will still be details of the peripheral vision that we will not pay attention to due to biological reasons.
How to calculate the field of view?
At this point, it's smart to ask yourself how to calculate the optimal field of view, right? Well, first we have to make sure that our eyes are located in the middle of the screen, as well as that the monitor/screen is at the ideal height. To learn more, take a look at the ergonomics of the desk.
The screen has to be aligned with our eyes, neither be above nor be below. Afterward, we can make use of a FOV calculator, there are many available by searching Google. Ideally, someone will help you with a meter to measure the distance between the monitor and the seat.
We warn you that what the calculator says is not final, but rather it is guiding and recommended. What you have to pursue is to feel comfortable at the desktop and with what you see in the game.
Resolution and FOV
It was to be expected that a high resolution will allow us to play more with the FOV, making special mention of the ultrawide or ultra-wide monitors. Where the field of view is most used is horizontally (within video games), and their ultra-wide monitors are very useful.
Is it because of the resolution that we see in the ultra-panoramas? No, it is because of the aspect ratio. This is the one that will allow us to take advantage of more or less FOV, and it turns out that a normal monitor has an aspect ratio of 16: 9, while an ultrawide monitor is usually 21: 9 at least.
There was some controversy with Overwatch and the field of view, clarifying Blizzard that they were going to limit it to 103 degrees so that those who had an ultrawide monitor would not benefit from others who did not.
