What is VSync in games and should it be enabled

Dozens of technologies are available related to 3D graphics in general, and games in particular. Perhaps one of the most prominent of these technologies is the VSync feature, which is among the options for most electronic games, whether they are newly launched or relatively old.

Many users struggle to understand the purpose of this technology. Especially users who do not play heavy electronic games. That is why we explain all its details in this article, especially as it expresses one of the basic concepts in World the games.

VSync is an abbreviation for Vertical Sync. This technology interferes with the way the personal computer generally deals with and processes graphics, a process that is based on the graphics processor.

The way VSync works does not differ depending on the shape of the GPU. It is supported by discrete graphics processors or those integrated within the central processor.

The graphic processor is generally used to create any content that the user can see on the screen. This means that the content of this article is visible to you thanks to the GPU in your device of any type.

VSync in games

The graphics processor is relied upon to configure the content displayed on the screen, as mentioned previously. The process is simple if the content is text or static images, but it becomes more difficult when the content is 3D.

This is because the GPU is producing consecutive frames very quickly to be rendered, thus creating visual gaming content as well as some other visual elements.

Frame rate is known as FPS for the number of frames produced per second. Naturally, the entire image is transmitted to the screen to be displayed. However, sometimes the graphics processors manage to produce too many frames for the screen’s capabilities.

In the event that the monitor does not offer a high refresh rate, it is only capable of displaying 60 frames per second. Here the problem occurs, as the graphics processor produces – for example – 100 frames per second, while the screen displays only 60.

This causes a problem known as screen tearing. This is because the screen content appears to be split in half at random.

VSync comes into play at this point. As it synchronizes the frames produced by the graphic processor with the screen, and technically, this feature succeeds in this by relying on what is known as the “freezing process”. The technology freezes the output of the GPU until the frames that have been produced are displayed.

Do you have to activate it?

The features of VSync have previously been explained in a simplistic manner, and although it seems like an ideal technology, this is not always the case.

This is where this technology depends mainly on preventing the visual content from reaching the screen until it displays the content sent to it previously. This causes a delay in response, so this technique is never suitable for competitive games.

Therefore, it is recommended to try the feature and its effectiveness in each game separately, and there are always options to enable or disable VSync within the graphics settings within the games.
