What is Vertical Synchronization and What it is for? (V-sync)

Vertical synchronization is also a function of the graphic configuration of video games and 3D applications that synchronizes frames per second (FPS) with the frequency of the monitor. Activating this function maintains more fluidity in the FPS and better stability in the image and these are limited according to the frequency of the monitor.

Turning on vertical sync depends a lot on the power of the graphics card and therefore can reduce performance. If the graphic card (video card) you are using is not powerful enough to run in a stable manner the game in which that function is activated you may have performance problems because it requires more use of the GPU (Graphics Processor Unit).

FPS is limited to monitor frequency

As I explained the vertical sync keeps the FPS limited to a number that is according to the heir of the monitor you are using. For example, if turning on vertical sync once the FPS was limited to 60 means your monitor probably works at 60HZ.

To be sure of that you can read the technical specifications of your monitor as also the monitor’s hz are linked the screen resolution of the same. Bone, every screen resolution that has available the monitor has a specific frequency. For example, it can be 1920x1080p 60HZ, 1336 × 768 50HZ, ect.

Another thing that happens and makes it necessary to use the vertical synchronization is when the graphics card is of a very high range for the monitor you are using can cause the FPS to increase too much and have sudden peaks of images per second and that could provoke Instability in the image.

That is something that many people know as “screen tearing”. In the following image, you can see what I mean.

Sometimes the tearing is less noticeable and only small distortions in the images.
