How to Enable NVIDIA Fast Sync?

Welcome Readers, this article is offering by the website windowsfixer, and below in this article, I am going to share the complete information through which you will be able to know about “How to Enable NVIDIA Fast Sync?

If you always play games on your computer by using a traditional monitor, then you must have noticed screen tearing issues. The main reason behind this issue is that the rendering rate of the graphics card is out of sync with the refresh rate of the monitor.

Let’s suppose you have a 60 Hz monitor capable of displaying up to 60 fps, but your GPU is working on anything above 60. As a result, you will notice that some items are not fully lined, interrupting your gameplay session.

NVIDIA has a solution for you as long as you own a Pascal or Maxwell-based GeForce GTX graphics card. Before going to know about how to enable the NVIDIA fast sync feature on your system, first, you should have to know well about this technology. So now, let’s take a look below to know more about it.

What is Screen Tearing?

As we know that, NVIDIA Fast Sync is mainly designed to reduce screen tearing and delay, we should have to know what the former is so that we will be able to know about the advantages of the Fast Sync. Screen tearing appears where you will see the disconnect between two parts of the screen. Let’s imagine, that you are looking at a corner of the wall in a game and it seems like a top half is half an inch to the right of the bottom or left, it is tearing.

You will get a Screen tearing issue when there will be a mismatch between the speed on which the graphics card sends the image as well as the speed on which the monitor can show it. While using a 60Hz monitor, then it means a refresh every 16ms. When the graphics card sends a frame too early, then the Screen tearing appears as the monitor is not ready for it. Due to this tear, you will be able to see part of the old frame and the part of the new one and they will not be able to match.

V-Sync was mainly designed to synchronize the GPU as well as monitor refresh rate but it came at a cost, latency. Latency always came when the graphics engine would be choke because there was still a frame in the back buffer for delivering of the monitor.

What is NVIDIA Fast Sync?

If you have ever tried to use V-Sync, you may have noticed a decrease in screen tear but an increase in input lag. If you play fast-paced games, then this information will be true for you. Most of the pro gamers always preferred to deal with the screen tearing than the latency of the V-Sync, so it went largely unused. NVIDIA is mainly designed to fix fast sync.

To get introduced with the last rendered buffer, NVIDIA hopes to eliminate both screen tearing as well as latency. NVIDIA already uses a back buffer as well as a front buffer to render the frame.

The graphics engine feeds the back buffer with a full-frame that is fed into the new final render buffer. The engine then immediately moves to the next frame. The last rendered buffer sends frames to the front buffer that continuously scans for new frames and sends them to the monitor.

Adding an extra step to the process allows a small amount of time for the GPU to deliver a full-frame to the monitor without latency. This is because a back buffer is always available to receive another frame from the engine. This continuous shuffling of frames coordinates to deliver frames as fast as hardware is enabled. The result is the delivery of the maximum frame to the maximum number of hardware that the hardware is able to deliver and display.

The benefit to gamers is obvious. If you were using V-sync you would get less screen tearing with any latency. When you are playing fast-twitch, it can make a real difference.

How to Enable Fast Sync Using NVIDIA Control Panel?

In your computer, if you have a supported GeForce GTX graphics card which is GTX 960 or newer, then you can easily enable it on the NVIDIA Control Panel. This software always comes with your graphics drivers and then you will not have to install it separately. So, just follow the below-given steps to enable Fast Sync using the NVIDIA Control Panel.

  • First, you have to right-click anywhere on your computer and then you have to click on the “NVIDIA Control Panel” to get open the software.
  • Then there you have to click on the “Manage 3D settings” that you can find on the left pane of the software.
  • Once it did, then you have to scroll down in the right pane and there you have to click on the “Vertical Sync” option. And then you have to choose “Fast” from the dropdown and then simply click on “Apply” to save all these settings.

So, all the information that I have mentioned above in this article will be enough, if you want to enable NVIDIA Fast Sync on your computer. However, you have to be sure that V-sync is disabled on all your computer games, as some games have this option to turn on by default, resulting in Fast-Sync may not work the way you want. You will be able to disable it to make your visit to the Graphics/Video settings of any game.

How to Use Fast Sync to Eliminate Screen Tearing Issues

With a capable GPU, if you have a general monitor that is able to render at a frame rate above the refresh rate of your monitor, then the Fast-Sync completely resolves all screen tearing issues, offering only a minimal lag. For this, you will not have to spend a fortune along with buying a G-Sync monitor.

However, if you have a G-Sync monitor, but your GPU is providing at a frame rate above the refresh rate of your monitor, then you will still face screen tearing issues unless you enable the Fast-sync. I think that NVIDIA has done an unprecedented job by offering this new technology that can really benefit gamers who have had many issues with the traditional V-sync.

Final Words

I hope, all the information that I have mentioned above in this article will be beneficial for you.
