Wondering what VSync is and how it works? We list it all for you and explain the benefits it offers your gaming.

VSync, or Vertical Sync, is a useful setting to solve the common problem of screen tearing. Essentially what it does is sync your frame rate with your monitor’s refresh rate. With these two under control, you should notice that your image is no longer tearing in the middle of the screen when you rotate or look around.

Do I need to enable VSync?

If you have a monitor with a high refresh rate or a game that performs better than your current setup, you absolutely need to enable VSync. This can be a way to force your game to meet your needs even after disabling the frame rate limits in some PC games. Please note that enabling VSync may increase system latency.

With esports (e.g. Counter-Strike), screen tearing can be a problem to ruin your games. This can be fixed by enabling VSync, which forces your game to limit the frames per second to the monitor’s refresh rate.

So if you get 200 FPS in CS:GO on your current system, but experience screen tearing because you don’t already have a high refresh rate monitor, this will force it into a 60Hz arena, where the game will be limited to competition.

Does VSync affect my game’s performance?

Since it’s a way of forcing your games to lower frame rates, it can start to affect performance if you’re suffering from a monitor or a poorly optimized game.

VSync will try to find the perfect point, but since it’s not ‘smart’ you might find it too aggressive. At this point you should start limiting FPS to try and fix the problem.

What are G-Sync and FreeSync?

Nvidia and AMD have provided monitor manufacturers with technology that allows the graphics cards in your PC to take more control over the VSync issue.

This means that by using the processing power of the GPUs, these particular monitors allow more control over vertical sync in an attempt to get around screen tearing. It was introduced with the GTX 650 Ti. However, due to likely licensing issues with Nvidia, AMD’s FreeSync is the most popular option among gaming monitors.

You don’t need an AMD card for this either, as it’s more open and also allows for Nvidia’s GPUs.
