This can cause your graphics processor to overheat, as it outputs frames at an incredibly fast rate. Because VSync makes frames wait for when the monitor is ready, this can cause problems. You may find that your inputs, such as key-presses and mouse clicks, are slightly delayed. This can be fatal in games that require reflex and snap reactions to play. The result is an even bigger drop in frame rate during intense moments. Technologies such as triple buffering can help prevent this, but it may not be an option everyone has access to.
The above descriptions refer to the default VSync function that has existed for years on PC. However, more recently, the hardware powerhouses of the games industry have begun coming up with new and improved forms of VSync that negate some of those problems.
This groundbreaking tech came out a couple of years ago and does the ingenious work of adapting your monitor refresh rate to your gaming framerate. The result is a completely smooth gaming experience if your GPU can handle it, that is , with no screen tearing, stutters, latency, or sharp FPS drops that accompany standard VSync.
If you want to know more about G-Sync, we wrote a whole article about it here. So, should you turn VSync on or off?
As you can see, it depends on your use case. In general, if your graphics processor is rendering more frames than the monitor can display, it may cause excess heat and screen tearing. When used correctly, VSync can help smooth out issues and keep your graphics processor from running red-hot. When used incorrectly, it can needlessly harm your FPS and cause input lag without benefit.
Now you know what VSync does and when to enable it. Borderless windowed mode also comes with a very efficient vsync built-in, which many people report reduces tearing and input lag, so give it a shot if your game supports it. If a game offers it, you should use it instead of vsync in most cases. Also read: Graphics Card Not Working?

Theoretically, this sounds like a perfect solution, but there are several issues and these are the reason why VSync is largely considered obsolete in As a result, the monitor will leave the previous image on display until the next one is ready, which causes visual stuttering.
Fortunately, there are now technologies much better equipped to deal with this problem, but more on those later. Likely the biggest issue with VSync is its input lag. This is particularly frustrating in games where quick reactions are necessary, such as a shooter game.
From what has been said so far, the simplest answer would be yes, you should use VSync. The advantages are clear, while the disadvantages are less likely to hinder you. The reason for this is simple: there are better alternatives. It was a good solution at the time and became a staple of graphics settings throughout the ensuing decade. While we can commend VSync for its success, we have to admit that its time has largely passed and that there are now better alternatives available.
How is that different from VSync? AdaptiveSync changes the refresh rate of the monitor and forces it to wait until the frame is ready before loading it up. You can take a look at the image below to better visualize this. FastSync attempts to achieve the same thing as the AdaptiveSync standard but runs into some issues where stuttering and chopping are more noticeable.
The same issue that affects FastSync, occasional stuttering , is also noticeable here. Because of its nature and how it works, you essentially force the graphic card to send frames when the monitor is ready to refresh and receive them; you introduce latency into the mix.
Take this as an example: You press R on your keyboard to reload a weapon, the keypress gets instantly registered, but since your monitor is not yet ready to receive the new frame in which your gun is reloading, there is a slight delay that occurs, and your weapon will actually reload after that slight delay, and you will likely notice this as well.
This can be fatal in competitive games where quick response times are critical. Another significant disadvantage is that it does not account for frame drops. Vsync is typically useless when the frame rate is 60 or less. Vertical synchronization is good as is, but there are many different types of it available these days that are developed by graphics manufacturers.
These are just Vsync derivatives instead of substitutes or alternatives. They try to build upon the original promise of Vsync by adding in new features or improving the old issues that come attached to it. It was created by keeping minimal stuttering in mind. This technology calculates and figures out a stable frame rate than your video card can maintain the game and then runs the game at that frame rate all the time, bumping it up only when the video card can handle and sustain the higher frame rate without dropping any frames.
Adaptive Sync basically acts as a smart toggle for Vsync. It keeps Vsync turned on when the FPS is higher than the refresh rate, but as soon as the frame rate drops below 60, it turns off Vsync so that you experience minimal lag and stuttering. This is vital in online games where any even small lag can prove to be a match-losing factor. GSync makes the refresh rate of your monitor variable and always keeps changing it to match it with the ever-changing frame rate of your game.
This continuous change results in a panel that has a fixed maximum refresh rate but a variable one otherwise. Not all monitors have that, and Gysnc compatible monitors are usually more expensive than standard monitors. Still, the experience that GSync provides is groundbreaking as it reduces all lag, stuttering, latency, and, most importantly, screen tearing from your game and offers unmatched immersion. It was made to prioritize smooth gameplay over better visuals.
FastSync automatically adds in a third frame buffer enabling triple buffering and works on any frame rate, whether low or high. It does precisely the same thing but now for AMD video cards! However, the good thing is that FreeSync monitors are typically cheaper than the GSync ones. FreeSync is, however, not a hardware-based remedy; instead, it relies on software to utilize variable refresh rate.
AMD released a driver update in to start supporting adaptive sync, which later evolved into what we know as FreeSync today. Enhanced Sync allows cuts down on the lag that comes with screen tearing and targets a smooth experience rather than a more beautiful one. Plus, Enhanced Sync provides this smooth experience at virtually all frame rates. Vsync is a software-based solution present in every modern game and can be used on every display and every video card.
In fact, Vsync and these two technologies even work slightly differently. They make the refresh rate variable and always try to keep up with the varying frame rate.
That feature is exclusively reserved for GSync and FreeSync monitors, which again are more expensive. GSync and FreeSync are the same things just made by different manufacturers for their specific product portfolios. They do the same thing and achieve the same results, and in fact, Nvidia has started to allow its GSync technology to be able to run on FreeSync compatible monitors. This is a question you should ask yourself. Vsync is worth it if you have a card that produces more frames than your monitor can handle at a time and if that monitor is capped at around 60hz so 75Hz is also counted here.
It is a great feature that can help reduce screen tearing alongside lag and stuttering.
