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?

When conventional vsync is enabled, the GPU is no longer able to replace the contents of the monitor buffer with a new frame, before the old frame gets its This means every frame gets to be displayed in its entirety, eliminating screen tearing.
However, this forces the GPU to queue up frames, instead of sending them as fast as possible. This is where low-lag vsync comes into the picture. You will also need an active internet connection, so that you can access these two web pages for running tests:. If you have a 60 Hz panel, it will likely be very close to 60, but off by a few hundredths of a second. If you have extra time on hand, use both to see if the numbers align.
The test page will show your display's refresh rate down to several decimal places. Round it to three digits for the next step. Once you have Rivatuner installed, make sure to run it with administrative privileges. Browse to the install location for your game.
Note, you can set this globally, too, we prefer customizing on a per-game basis. Take your three decimal-place refresh rate, then subtract 0. If your refresh rate is In the Rivatuner interface, select the game on the left hand side. Then, type in your frame rate cap in the box next to frame rate limit. You've now limited your game's frame rate to just under the monitor's refresh rate.
You'll want to play around with this number a little bit. Some games are more sensitive to frame capping than others: if you experience lots of judder, trying adding to the frame rate cap by increments of 0. Launch your game, then make sure to enable vsync in settings.
With low-lag vsync enabled, you'll enjoy substantially better input latency without screen tearing. There are a few caveats you'll need to pay attention to. Low-lag vsync works best if your system is capable of running consistently above the monitor's refresh rate.
If you're just hitting the 60 FPS mark, enabling this could cause additional stutter, whenever frame rates dip below. If you don't want to play around with fractional frame rate capping, RTSS offers an alternative: scanline sync.
