If you’ve spent any time gaming on PC, you’ve likely come across the term VSync and maybe even its more advanced cousins, G-Sync and FreeSync. Short for vertical synchronization, VSync is a display feature that keeps your monitor synchronized with your GPU’s frame output, ensuring smoother visuals and reducing screen tearing.
It’s also one of the key technologies you’ll find on some of the best monitors on the market.
In this guide, we’ll break down what VSync actually does, how it affects your gaming experience, and when you might want to turn it on or off for the best performance.
VSync is a graphics technology designed to sync a game’s frame rate with the refresh rate of a gaming monitor. Originally pioneered by GPU manufacturers, this technology was introduced to address the issue of screen tearing, which occurs when your screen simultaneously presents portions of multiple frames.
This can lead to visual artifacts resembling the example shown above, typically manifesting as a horizontal split in the display. Screen tearing arises when the monitor’s refresh rate (the frequency at which it updates per second) is not synchronized with the frames per second being produced by the graphics card.
Screen tearing can occur at any time, though it is most prevalent during fast motion, particularly when a game runs at a higher frame rate than the monitor can handle or when the frame rate changes dramatically and the monitor can’t keep up. It is particularly noticeable during fast-paced games with vertical image elements, such as trees, entrances, or buildings. When this happens, those lines will quite clearly not line up correctly, which can break immersion and make a beautiful game look rather ugly.
VSync does a few things to help alleviate this. First, it limits the frame rate output by the graphics card to the monitor’s refresh rate (60Hz, unless you have a high-refresh-rate monitor), making it easier to avoid higher frames per second than the monitor can handle.
It does this by preventing the GPU from doing anything to the display memory until the monitor has concluded its current refresh cycle — effectively not feeding it any more information until it’s ready for it. Through a combination of double buffering and page flipping, VSync synchronizes the drawing of frames onto the display only when it has finished a refresh cycle, so you shouldn’t ever see tears when VSync is enabled.
VSync only helps with screen tearing, and it only really does that by limiting FPS (frame per second) when necessary. If your monitor can’t keep up with the FPS of a particular game, then VSync can make a big difference.
However, VSync cannot improve your resolution, colors, or brightness levels like HDR. It’s a preventative technology that’s focused on stopping a specific problem rather than making improvements. It also tends to harm performance.
By forcing frames to be entirely rendered before being displayed, your FPS can suffer, and at best, your frame rate is limited to the refresh rate of your display. In some games where higher FPS can lead to reduced input lag, it can also affect your competitive performance. If you really want to make the most of your PC’s gaming capabilities, it’s important to fine-tune your settings to the max.
You don’t need a particular monitor to use VSync as it’s designed to work with all kinds of displays. What you need is a graphics card that supports it and most recent generations support it throughout the product lineups.
VSync has been around for many years, and both Nvidia and AMD have options to enable the setting in their drivers for all games.
However, if you’d prefer to do it on an individual game basis, most games offer it as a toggle option in their graphics settings menu.
VSync is far from being a perfect solution and can negatively affect your gaming experience, even if it is useful and working as intended. If a monitor and a game are having trouble syncing up, then VSync can lower your frame rate significantly to try to find a point where they can.
That can lead to input lag and stuttering increases, which worsens the gaming experience. Screen tearing is most noticeable in fast-paced games like shooters and fighters, but it can affect all sorts of games regardless of genre.
That’s why, if you’re particularly serious about these types of games, enabling VSync might not be worth it. Another setting, called triple buffering, can help reduce some of VSync’s problems, but this doesn’t come with any guarantees.
Here’s where things get a little more complicated. GPU companies were well aware of VSync’s potential problems when it was first released, and they’ve been trying to make improved versions ever since.
That’s why, when you go into your GPU control panel, you may see different syncing options. More advanced forms of VSync include:
Nvidia’s G-Sync and AMD’s FreeSync aim to improve on VSync abilities. Both GPU technologies work to sync refresh rates and data with your GPU’s frame rate.
The companies wanted to end problems with VSync, particularly image precision and uniformity, and tears. Essentially, G-Sync and FreeSync are more effective versions of the VSync software. If they are available to you, we suggest trying them out.
However, these technologies are compatible with your graphics card and monitor. Most monitors have G-Sync or FreeSync, but there’s minimal support. Since they are competing software, you’ll have difficulty finding a monitor that uses both.
In the end, you will likely have to attempt to match your monitor’s capabilities to your GPUs. As long as you understand both units’ technical specs before purchasing, this is relatively easy to accomplish.
Most, if not all, modern Nvidia and AMD graphics cards offer access to either G-Sync or FreeSync. VSync, on the other hand, should be available to pretty much everyone — if your PC can handle games, it can support VSync.
Nvidia users will need at least a GTX 650 Ti GPU for basic G-sync compatibility and a GTX 1050 or higher for G-Sync HDR. This means that if you own one of the best graphics cards, such as an Nvidia RTX 5070 Ti, you will definitely have access to G-Sync. However, keep in mind that your monitor matters too, as only some monitors support G-Sync. G-Sync is available on both Windows 10, and Windows 11.
AMD FreeSync is also fairly accessible. Not only can it be used by AMD GPU owners, but some Nvidia GPUs support it too. In order to run AMD FreeSync on a Radeon graphics card, you will need at least an AMD Radeon RX 200 series GPU. FreeSync is also available on compatible desktop AMD Ryzen APUs which include integrated graphics solutions.
If you have a graphics card that supports VSync, you can easily enable it to ensure smooth performance on most displays. VSync can be activated either through the AMD FreeSync (AMF) technology or the Nvidia App. Alternatively, you can toggle the VSync setting within the graphics options of your game.
To guide you through the process, here’s a simple step-by-step guide for enabling VSync using the Nvidia App on your PC:
Whether you should keep VSync on or off largely depends on your gaming setup and priorities. Enabling VSync helps eliminate screen tearing and it’s particularly useful if you have a standard 60Hz or 75Hz monitor, as it ensures smoother visuals and a more polished gaming experience. It also prevents your GPU from rendering unnecessary frames, which can help lower power draw and fan noise on laptops or quieter desktop builds.
On the other hand, enabling VSync can potentially introduce input lag and occasional stuttering, especially when your GPU struggles to maintain stable frame rates. This delay can be noticeable in fast-paced shooters or competitive eSports titles where reaction time matters most.
Many gamers today prefer alternatives like G-Sync, FreeSync, or Adaptive Sync, which achieve similar tear-free visuals without the latency drawbacks. If you have a high refresh rate monitor and a powerful GPU, keeping VSync off usually gives you a more responsive, fluid gameplay experience, but for casual or story-driven games, leaving it on can make visuals look cleaner and more consistent.
