What Is VSync And Should You Use It?

You may have seen a weird option in the video settings if you use 3D programs or games. It’s referred to as “vertical sync” or “Vsync” for short, and its purpose isn’t immediately evident.

Vsync was the first GPU, video game, and monitor synchronization technology. Despite the introduction of as GSync and FreeSync, many gamers still rely on Vsync.

What Is Vsync Technology?

Vsync (vertical synchronization) is a term used to describe a type of vertical sync. It synchronizes a monitor’s refresh rate and frame rate. GPU makers created this technology to combat screen tearing. When your graphics card shows sections of multiple frames at the same time, screen tearing occurs. Displays may appear to be split horizontally. Tearing occurs when the frames per second do not match the GPU’s refresh rate.

Screen tearing can occur at any moment. It is especially noticeable in vertical objects such as buildings and trees. Usually, when playing high-speed games with rapid rate changes.

Vsync corrects this by limiting the monitor refresh rate of the graphic card to the frame rate. As a result, higher frames per second than the monitor’s capacity are avoided. To display frames, it employs page flipping and double buffering.

Different Types Of V-sync

There has done a lot of work put into launching better and new versions of V-sync. The gaming industry has begun developing new technology. New and improved types of Vsync to address some of these issues.

Nvidia G-Sync 

Nvidia GSync

Nvidia put in a lot of effort to fix the V-sync issues. Nvidia chose to change the game by launching Nvidia GSync. It happened after releasing Nvidia Adaptive-Sync and Nvidia Smooth V-sync. It adjusts the refresh rate of your monitor to match your gaming framerate.

It smooths out the gaming experience. It eliminates screen tearing, stutters, FPS decreases, and latency that traditional V-sync causes. You may require a G-Sync monitor and an Nvidia GPU.

AMD FreeSync

AMD FreeSync

As a response to G-Sync, NVidia responded with FreeSync. To make it work, you’ll still need a FreeSync-capable monitor and an AMD GPU. The improved version simplifies things.

It’s exclusively compatible with AMD Radeon graphics cards. It complements rather than replaces Vsync. When the FPS falls below the screen’s refresh rate, they work together to decrease input latency and stuttering.

Increased Sync increases the consistency of performance and overall capability. If performance degrades, Enhanced Sync is disabled to maintain frame rates.

How To Turn Vsync In The Nvidia Control Panel

Vsync can be used with any display, but it requires a graphics card that supports it. It is supported by the most recent monitor models across their product lines. Vsync may be enabled in both AMD and Nvidia card drivers.

Most games provide a toggle for this option in their options. It’s simple to enable Vsync with Nvidia. To switch it on and off, follow the steps below.

  • In Windows search, look for the Nvidia control panel.

What Makes Struggle Between FPS?

smooth vsync reduces stuttering

When your graphics processor starts to emit more frames than your monitor can handle, problems arise. Your monitor may strive to keep up with the action, resulting in two frames being out of sync. It is known as “screen tearing,” It occurs when an image appears to be “split in half.”

VSync comes in handy here. VSync aims to fix syncing issues by matching the graphics processor’s frames with the monitor’s refresh rate. The game engine is usually frozen, or frames are buffered to do this. It’s finished when the monitor is ready to display the next frame.

Does V-sync Technology Make A Big Improvement?

V-sync Technology Improvement

Vsync is solely helpful for preventing screen tearing. It only achieves this by restricting the number of frames per second (FPS) as necessary. Vsync can make a significant difference if your monitor can’t keep up with a game’s frame rate.

HDR can boost your resolution, colors, and brightness levels, but Vsync can’t. It’s a technology that works to keep things from happening in the first place. It is more concerned with resolving a single issue than with developing improvements. It also has a negative impact on performance.

Your FPS may suffer as a result of forcing frames to be rendered entirely before being displayed. The refresh rate of your display determines your frame rate. In some games, a faster frame rate can result in less input lag. It can also produce an impact on your competitiveness.

Should I Enable Vsync Technology or Not?

Your graphics processor may be more potent than your monitor. If the screen starts to heat up and tear, you should turn on V-sync. Activate V-sync in the software or the graphics processor’s settings.

Suppose your graphics processor is slower than the refresh rate of your monitor. V-sync will simply exacerbate issues such as input lag. As a result, it’s best to avoid using V-sync in these scenarios and turn it off.

What Are Adaptive Vsync And Fast Sync and Other V-sync?

Different synchronizing options may be available in your GPU control panel. Vsync can be used in more advanced ways, such as:

Nvidia’s Adaptive-Sync

It is an Nvidia enhancement that monitor’s the max refresh rate of the monitor. Vsync is activated if the game’s FPS is equal to or higher than the refresh rate. It is disabled if the FPS goes below a certain threshold. It prevents the occurrence of some input latency issues.

Enhanced Sync 

AMD’s version of Fast Sync is called AMD Enhanced Sync. To avoid difficulties, it disables Vsync when the frame rate falls below the monitor’s refresh rate.

Smooth Vsync

Smooth Vsync is used to reduce stuttering while SLI and Vsync are present. SLI boosts processing capability by allowing GPUs to work in parallel. When enabled, SLI allows four GPUs to work together to render games at high frames per second. Smooth Vsync eliminates stuttering and maintains a consistent frame rate.

Fast Sync

FAST SYNC is an improved version of adaptive VSync from Nvidia. Automatic triple buffering is used to select the best frame data when Vsync is needed. The computing power required to operate it is considerable; nonetheless, it can assist with a wide range of Vsync issues.

Is Vsync Better Than G-sync Or Freesync?

G-Sync from Nvidia and FreeSync from AMD both strive to improve Vsync’s capabilities. Both GPU technologies aim to keep refresh rates and data in sync with the frame rate of your GPU. 

The companies aimed to eliminate Vsync issues such as image precision and homogeneity, as well as tears. G-Sync and FreeSync are essentially improved versions of the Vsync software.

Your graphics card and monitor are compatible with these technologies. G-Sync or FreeSync

is available on most displays. You’ll probably have to try to match the capabilities of your monitor to your GPUs.

G-Sync and FreeSync are both excellent options. While Vsync functions, it just provides the bare essentials.

Pros And Cons Of Vsync Technology


You’ve already noticed screen tearing, and it irritates you. By regulating the graphic processor and the monitor’s refresh rate, V-sync will eliminate screen tearing.

When playing older games, Vsync can be helpful. Some apps, for example, ancient games. When compared to the graphical demand, the graphics processor outperforms. Graphic processors are extremely fast, which can result in a greater frame rate when playing older games.

It causes your graphic processor to overheat because it is working at a high rate. As a result, using Vsync will alleviate this issue by relieving the processor of unnecessary stress.


When it comes to synchronization frames, Vsync excels. It does, however, prevent your GPU from transmitting extra frames to the monitor. You’re playing a game with a quicker frame rate. Then there’s a lag between keystrokes and triggers.

It could be the most severe drawback of enabling Vsync in GPUs or game settings. There is a brief lag associated with it.

Another issue you can see is the frame rate drops below the monitor’s refresh rate.

If the frame rate falls below the monitor’s refresh rate, the GPU tries to increase the FPS to match the monitors. Most of these concerns may be addressed to some extent. Technology continues to present them. Triple buffering is a new technology on the market. It deals with input lags and other screen stutters.


Vsync is very useful when implemented correctly. It keeps the graphics processor from being overused and heating up. Misused, it can cause input lag and FPS drops. I hope after seeing this article, you will get enough knowledge about V-sync.


Is It Enough To Have Vsync On Or Off?

Neither tearing nor over-processing should be an issue. Aside from slowing down your frame rate and increasing input lag, Vsync has no other effects. As far as I know, this is the best way to proceed. With Vsync, you can keep your graphics processor running smoothly and cool at the same time.

Does Vsync Lower FPS?

If your frame rate and refresh rate are out of sync, Vsync is the solution for you! As a result of using Vsync, your graphics processor and monitor are able to work together seamlessly. Enabling Vsync reduces the number of frames per second that can be displayed. The highest refresh rate of your monitor minimizes the stress on your GPU.

Should I Enable Vsync?

Vsync only helps with screen tearing. It does so by restricting the number of frames per second (FPS). Your monitor can’t keep up with a game’s frame rate. Vsync can then have a significant effect. Vsync, on the other hand, cannot boost your resolution, colors, or brightness levels in the same way that HDR does.

Why Is Vsync So Bad?

Vsync forces frames to wait before they are rendered. It tends to introduce a small amount of input latency. This means, you’ll hit a button, but the response on your screen will be delayed by a few milliseconds.
