Known what is VSync and how it can help you with your video games

VSync was the first technology of synchronization to the graphics processing unit , or GPU, video games and monitors. Despite the fact that there are new options, like G-Sync or FreeSync, it is still an important alternative for many gamers. Do you want to know exactly what is VSync? We will learn what is VSync, why is it so important, what the problems are that eventually you can generate your use, how you can turn it on and the alternatives that you have available.

What is the technology VSync?

If you are a gamer, you’ll be interested to know what is VSync.

In simple terms, VSync, or vertical sync, is a graphics technology that synchronizes the frame rate of a game and the refresh rate of a monitor.

This technology was developed by the manufacturers of the GPU as a way of dealing with the failure of visual known as screen tearing or game screen. This problem occurs when two “screens” different from an image collide, because the frames per second (FPS) of the game delivered information that the refresh rate of the monitor is not able to follow. The results are images with faults, where the objects appear fragmented or part of the screen looks dislocated.

Usually this phenomenon occurs when you have games with 60 FPS or more, in addition to monitors that do not exceed a refresh rate of 60Hz. Anyway, you can sign up even if you have higher rates, but your game is particularly demanding , or you’re performing more complex tasks.

There it is when it appears VSync, imposing a strict limit to the FPS of the game. He says something to the game: “Hey, this seems to be a monitor of 60Hz which is struggling to keep up, so you’re not going to exceed 60 FPS, okay? Synchronizes the refresh rate and the image data“. The result is a gaming experience more smooth, which has no problem of screen tearing or at least that is the goal.

Does it make a big difference?

Vsync te ayuda con la falla visual conocida como 'screen tearing'.
Vsync will help with the failed visual known as ‘screen tearing’.

VSync only helps with the screen tearing, and it does so by limiting the FPS when it is necessary. If your monitor can’t keep up with the FPS of a particular game, VSync can make a huge difference.

However, VSync can’t improve the resolution, the colors, the brightness levels or anything like HDR. It is a technology that focuses on preventing a specific problem, instead of making improvements.

What do I need to enable the technology VSync?

La mayoría de los monitores tiene compatibilidad con Vsync.
Most monitors have compatibility with Vsync.

You don’t need any particular monitor to use VSync. It is designed to work with all types of screens. You need a graphics card that support this, but this should not be a problem for most of the monitors for gaming, even the most ancient: VSync has been around for several years, and both Nvidia as AMD have options to enable this setting. Whenever you have an Nvidia GPU or AMD that is not more than a decade, you should be able to use VSync.

However, the games do not have the options of VSync activated automatically. You will need to go to the game settings and make sure they are enabled: it is not guaranteed that make a big difference, but it is good to check and make sure. The most popular titles have this option, such as Fortnite, GTA V, Minecraft, Overwatch, among others.

What VSync generates a problem?

Problemas con VSync
When the FPS is very low, you may register problems with VSync.

Can generate problems. For example, if a monitor and a game really have problems to synchronize, then VSync can reduce the FPS even 30 FPS. This happens when the FPS of the game varies suddenly, due to processing problems and similar causes. The lower the FPS so that the game is designed, you will begin to notice delays in the inputs, which are especially annoying in those that require quick reflexes, such as the shooting games or fighting.

Thus, if you are you are seriously this kind of games, enable VSync might not be worth it. There is another setting called “triple buffering“, which may help to reduce some of the problems of VSync, but this also does not have any warranty.

What are the Adaptative VSync and FastSync?

Existen versiones mejoradas de VSync
There are improved versions of VSync.

Companies fabricantess GPU were aware of the possible problems with VSync when it launched, and since then have been trying to make improved versions. That is why, when you enter the control panel of your GPU, you can see the different synchronization options. The more advanced forms of VSync, which include:

  • AdaptiveSync: it Is an improvement from Nvidia that monitors the speed of updating the maximum of the monitor. If the FPS of the game is equal or higher to the update, VSync is enabled. If the FPS falls below, is deactivated, which prevents arise some problems of delay of entry.
  • FastSync: FastSync is a more advanced form of improved synchronisation of Nvidia that enables VSync when it is necessary and adds a triple buffer machine to always choose the best pictures possible. It requires a lot of energy, but it helps to solve many of the problems with VSync.
  • Synchronization improved (Enhanced Sync): The sync-enhanced is the version of AMD to fix the problems of VSync. As AdaptiveSync, disables VSync when the frame rate drops below the refresh rate of a monitor to avoid related problems.

How VSync is better than G-Sync Or FreeSync?

G-Sync y FreeSync son alternativas de los fabricantes de GPU.
G-Sync and FreeSync are alternatives of the manufacturers of GPU.

We get the latest ways to prevent screen tearing: G-Sync and FreeSync. G-Sync, Nvidia and FreeSync, AMD, are technologies of GPU to synchronize carefully the rate of update and other image data directly with your graphics card, to provide a sharper image, without the potential problems of VSync. Look at them as the definitive form of VSync, and certainly worthwhile to enable it.

The “trick” is that you need a graphics card with G-Sync or FreeSync and a monitor that supports this technology. Currently you can find many monitors that have support for G-Sync or FreeSync, but very few that have both, as they are proprietary technologies and competition. This means that you should make sure you get a monitor that matches the technology of your GPU and vice versa.

VSync, on the other hand, works better with older monitors that do not have G-Sync or FreeSync, but still need to handle the games in the best possible way. It is also a good alternative if your GPU is limited and you’re saving for an upgrade.
