What is VSync, and when should you use it?

VSync is the original synchronization technology for GPUs, video games, and monitors. Despite new options like G-Sync or FreeSync, VSync is still an essential choice for many gamers. But what does it do and is it still worth using? Let’s take a deep dive into what VSync is and why it’s important.

What is VSync Technology?

VSync, or vertical sync, is a graphics technology that synchronizes the game’s frame rate with the gaming monitor’s refresh rate. First developed by GPU manufacturers, this technology is a way to deal with screen tearing, when your monitor displays parts of multiple frames in one go. That can result in something like the image above, where the screen appears split along a line, usually horizontally. Screen tearing occurs when the screen’s refresh rate (the number of updates per second) is out of sync with the frames per second. the frame rate is higher than the monitor can handle, or when the frame rate changes suddenly and the monitor can’t keep up. It is especially noticeable in fast-paced games with vertical visual elements, such as trees, entrances, or buildings. When this happens, those lines will pretty clearly not line up correctly, which can disrupt immersion and make a nice game look pretty bad. First, it limits the graphics card’s frame rate output to the monitor’s refresh rate (60Hz, unless you have a high refresh rate monitor), making it easier to avoid higher FPS level that the monitor can handle. square root of 6 | The top Q&AIt does this by preventing the GPU from doing anything with display memory until the display has finished its current refresh cycle – without giving it any more information. until it’s ready. Through a combination of dual buffering and page flipping, VSync only synchronizes the drawing of frames on the screen when it has completed its refresh cycle, so you’ll never see VSync tearing. is turned on.

Does it make a big difference?

VSync only helps prevent screen tearing, and it only really does that by limiting FPS 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, color or brightness like HDR. It’s a prevention technology that focuses on preventing a specific problem rather than improving. It also tends to harm performance. By forcing frames to be rendered completely before rendering, your FPS can suffer, and at best, your framerate is limited to your monitor’s refresh rate. In some games where higher FPS can lead to reduced input lag, it can also affect your competitive performance.

What do I need to do to enable VSync technology?

You don’t need a specific monitor to use VSync – it’s designed to work with all types of monitors. You need a graphics card that supports it, but most recent generations support it throughout the product line. VSync has been around for years, and both Nvidia and AMD have options to enable the setting in their drivers for all games. in their graphics settings menu.

If your monitor and game have trouble syncing, VSync may drop your framerate significantly to try to figure out where it might be. That can lead to increased input lag and stutter, worsening the gaming experience. Screen tearing is most noticeable in fast-paced games like shooters and fighters, but it can affect all types of games regardless of genre. Another setting called triple buffering can help reduce some of VSync problems, but this doesn’t come with any guarantees.

What is Adaptive VSync and Fast Sync?

Dan Baker / Digital Trends This is where things get a little more complicated. GPU companies were well aware of the potential problems of VSync when it was first released, and they’ve been trying to make improved versions ever since. That’s why when entering the GPU control panel you can see different synchronization options. More advanced forms of VSync include:

• Adaptive VSync: This is an Nvidia improvement that tracks the monitor’s maximum refresh rate. If the game’s FPS is equal to or higher than the refresh rate, VSync is enabled. If the FPS drops below, it will be disabled, thus preventing some input lag issues from arising.
• Fast sync: Fast Sync is a more advanced form of adaptive VSync from Nvidia that enables VSync as needed and adds automatic triple buffering to select the best possible frame data. It takes a lot of power to use but also helps to fix a lot of VSync problems.
• Advanced Synchronization: Advanced Sync is AMD’s version of Quick Sync. It disables VSync when the frame rate drops below the monitor’s refresh rate to prevent related issues.

Is VSync better than G-Sync or FreeSync?

Rich Shibley / Digital Trends Vidia’s G-Sync and AMD’s FreeSync for improved VSync capabilities. Both GPU technologies work to synchronize refresh rate and data with your GPU frame rate. Companies want to end problems with VSync, especially with image accuracy and uniformity, and tearing. Essentially, G-Sync and FreeSync are more efficient versions of the VSync software. If they are available to you, we recommend trying them out, however, these technologies are compatible with your graphics card and monitor. Most monitors have G-Sync or FreeSync, but only minimal support is available. Since they’re competing software, you’ll have a hard time finding a monitor that uses both. In the end, you will likely have to try to match the capabilities of your monitor with your GPU. As long as you understand the specs of both devices before you buy, this should be relatively easy to do. G-Sync and FreeSync offer quality features. While VSync works, it offers minimal features.
