What is VSync & Should I Turn It On or Off? A Complete Review

7 min read

What is v-sync? It’s one of those terms that seems to be thrown around. But not many people know what is vsync means. Or why they should care about it in their games. VSync stands for Vertical Synchronization, and it’s used in video games to keep the frame rate from dropping too low or going too high. When you turn VSync on. The game checks to see if your current frame rate is higher than your monitor’s refresh rate. If it is, the game will automatically drop down to the refresh rate of your monitor. Thus keep the frame rate in check and avoid juddering animation or tearing. Let’s figure it out together. We’ll also discuss whether you should turn on vsync in your games!

What is vsync technology?

In simple terms, it synchronizes your game’s frame rate to your monitor’s refresh rate. Your game can output frames as quickly as it wants (within the game’s settings) but will never go above your monitor’s refresh rate. This means that if you’re running at 60fps on a 144hz monitor (generally considered the best experience for gaming). VSsync would never allow anything to exceed 60 frames per second on screen. Turning vsync off will force games to run at an unlimited frame rate which could lead to screen tearing and an unsatisfying gaming experience.

If your computer has an Nvidia GPU, then v-sync turn off better for performance. Because Nvidia cards work better with G-Sync enabled. If you have an AMD graphics card, however, this may not the case. And might be more beneficial to turn on the v-sync instead of turning it off. Some argue that having V-Sync turned on causes input lag because more frames are rendered than necessary. However, others say that any input lag cause by v sync is minimal compared to the benefits of reduce stuttering and juddering from having v-sync turned off altogether. What do I think about what is vsync? What do YOU think? Do some research yourself! You’ll need to decide what’s right for YOU!

How VSync affects your gaming experience?

VSync stands for Vertical Sync. Enabling VSync in a game will force the game’s frame rate to limit to the refresh rate of your monitor. And How VSync affects your gaming experience. VSync is typically turned off by default and can turne on via the in-game graphics settings menu, after you install the latest version of your video card drivers. Does VSync help FPS? No, not really. Enabling it doesn’t magically increase your frame rates but decreases micro stuttering and other issues that occur when a game’s frame rate starts to go out of sync with its refresh rate on a monitor.

What is v sync? Enabling VSync in a game will force the game’s frame rate to limit to the refresh rate of your monitor. What is vsync? Is there any difference between vsync and fps caps? No, not really. Enabling it doesn’t magically increase your frame rates but decreases microstuttering and other issues that occur when a game’s frame rate starts to go out of sync with its refresh rate on a monitor.

What do I need to enable VSync?

VSync does precisely what it sounds like: it synchronizes your graphics card and monitor so that frames are shown in perfect synchronization to the refresh rate of your monitor. For example, if you have a 144hz monitor, then vsync will cause the game to only update at 144 fps on the monitor instead of potentially higher. So, you may ask yourself if my graphics card can handle more than 144 fps.

So, I need to enable VSync technology. What is vsync? VSync helps to synchronize my graphics card and monitor for smooth, fluid gameplay without tearing or stuttering. Does vsync support fps? Yes! When enabled, it will help keep the framerate consistent by only updating the screen every time a new frame is ready. What is vertical sync? Vertical sync locks down your framerate to match your monitor’s refresh rate for smoother gameplay without tearing or stuttering.

Does VSync have any problems?

Yes, the biggest issue is that if your monitor refresh rate exceeds the refresh rate of your game. It will lower the frame rate to match the display. For example, if you’re playing an FPS at 60FPS and your monitor’s refresh rate is 75Hz, the framerate will drop to 30FPS to keep up with the demand of displaying 60 frames per second on a 60Hz screen. VSync will also cause lag in games when running faster than what’s shown on-screen. So, what does this mean for me? When should I turn Vsync off? There are two scenarios were turning Vsync off might be preferable: when you want to achieve higher frame rates and play competitively.

There are several options when it comes to Vsync. One option is to turn Vsync off completely, which would fix all the problems above and give you the best possible performance from your hardware. Another option is triple buffering, which uses more memory resources but reduces tearing issues. The third option is adaptive vsync, which automatically turns vsync on or off depending on whether the framerate exceeds your display’s refresh rate.

How to enable VSync?


VSync works on most monitors and displays, so long as you have a graphics card that supports the feature, but at this point, it’s something that all modern discrete GPUs should keep out of the box. You can enable VSync via AMD and Nvidia’s respective drivers or toggle it in a game’s graphics settings. To give you an idea of how it’s done, here’s how to enable vsink through Nvidia’s control panel on your PC. 1. Hit the Start button and type Nvidia control panel, then press Enter to launch it. 2. Click Manage 3D Settings on the left-hand side of the Nvidia control panel. 3. You’ll find Vertical Sync in the Global Setting tab.

Advantages of VSync


VSync is worth a try if you’re experiencing screen tears. This will bring your graphics processor down to the same level as your monitor and allow them to work better in unison, thus eliminating screen tearing. It can also be helpful in applications where your graphics processor severely overpowers the graphical demand. Because graphics processors go as fast as possible, rendering old scenes may result in exceedingly high frame rates. This can cause your graphics processor to overheat, as it outputs frames quickly. Enabling VSync will cap the FPS to the monitor’s refresh rate and stop the excessive strain on the graphics processor.

Are there disadvantages to VSync?

VSync works as intended most of the time, but there are instances where it can negatively impact your gaming experience. Since VSync makes frames wait for the monitor to be ready before displaying them, you can experience input lag. If you’re playing an intense competitive online match, this is the absolute last thing you want happening. It’s also possible for frames to drop below the monitor’s refresh rate during graphically demanding moments, which causes the frame rate to plummet further.

Enabling triple buffering may mitigate this issue, but that isn’t always reliable. A segment of players, particularly competitive types, aren’t fans of VSync because of the above issues. To that end, they purposefully disabled VSync to circumvent problems associated with the option. Granted, these issues aren’t commonplace, but it’s understandable why some choose not to turn VSync on. We should also note that VSync only fixes screen tearing. It won’t enhance a game’s graphics or performance.

Should you turn VSync on or off?


The answer to this question depends on what your monitor can do. If your monitor supports a refresh rate of 144 Hz and above, it’s best to keep v-sync off because it will limit the frame rate to 60 fps. With an FPS (frames per second) of 60, some stutters may happen now and then. These stutters don’t occur with turned off. But if your monitor doesn’t support a high refresh rate, it’s better to turn VSync on.

Screen tearing occurs when two different images are shown at once. For example, if you’re playing a game where one-character walks left while another nature walks right across the screen, when both characters cross each other’s path. There is screen tearing since the player sees one character walk left while seeing another character walk right at the same time.

Understanding Input and Output

There are two aspects to VSync: the screen’s refresh rate and input. The screen refreshes several every second, even though our eyes don’t see it. If the screen didn’t refresh, we would see a static image. So even when you aren’t playing games, the display still refreshes to show where the cursor is or how it’s moving. Your refresh rate measures how many times every pixel on the screen refreshes every second. It is a frequency unit measure in Hz (hertz).

So, if your display’s refresh rate is 90 Hz, every pixel refreshes 90 times every second. The higher the refresh rate, the better the experience you’ll have. For OLED or LCD panels, a monitor with a high refresh rate lowers motion blurring. Most desktops have a 120 Hz refresh rate and a resolution of 1080×1920 pixels. The refresh rate can be checked by navigating to advanced display settings and clicking on display adapter properties.

There are two outputs from rendering: the frames per second and the grinder that cuts the frame rate into pieces. The standard frame rate of a movie is 24 fps or 24 times per second. However, our eyes can handle over 1000 fps. While it might be easier on the eyes, gaming is not the same as watching movies because the frames-per-second tend to be slower. Frame rates of 60 are smooth and allow you to navigate at a more leisurely pace; displays with 90 or more frames per second would be preferable.
