What is NVIDIA Fast Sync and How to Enable It Easily?

Suppose you are a gamer who often plays games on the conventional monitor of computers. Then, you would have certainly observed issues of screen tearing indeed. Screen tearing is among the most apparent problems while playing fast-paced and heavy games, especially when using their mouse.

This happens because the rendering rate of graphics cards gets out of sync with the monitor’s refresh rate. Presume a situation when you have a monitor of 60 HZ, which has a capacity of displaying over 60 fps. Still, your GPU is rendering at anything more than 60, which means whereas Monitor < 60 whereas GPU > 60.

As a result, you will find that particular objects are not lined up flawlessly, thereby obstructing your gameplay session. Now, that is a thing that can irritate any gamer who is willing to play fast-paced games.

But, as we always say, there is a problem then, there is a solution too. Here, NVIDIA comes with a solution for you all. The only thing that you require is a Pascal or GeForce GTX graphics card, which is Maxwell-based. So, curious to know about what NVIDIA fast sync is and how to enable it?  

No issues; we will discuss this in detail. But before knowing how to enable the NVIDIA Fast Sync feature on your computer or PC, let us first discuss what this technology does…

What’s Fast Sync?

Now, the question arises what’s fast sync. NVIDIA has brought NVIDIA Fast Sync, the NVIDIA company’s newest and modern solution to fix all those screen tearing issues that gamers face while playing fast-paced games.

It keeps latency to a bare minimum, and thereby it turns up as a much better option than the conventional technology of V-Sync. NVIDIA Fast sync is introduced by the company to solve all those issues that pro gamers often experience.

GPU Requirement for Using Fast Sync

Undoubtedly, Fast sync NVIDIA can make this happen by introducing the latest “Last Rendered Buffer.” It stays here right between the Front and Back buffer. Initially, the GPU provides a frame into the Back buffer.

After this, the structure in the Back buffer will instantly move to the latest Last Rendered Buffer. Afterward, the GPU renders the next frame into the back buffer, and while this all happens, the frame in the last rendered buffer will shift to the front buffer.

Now when the Last Rendered buffer stays here for the next frame, from the back buffer. Meanwhile, the Front buffer goes through the scanning process, and the image will then deliver to the monitor. Now, the Last Rendered Buffer transmits the frame to the front buffer.

Consequently, scanning and displaying it on the monitor. Due to a result of this, the game engine is not hindered or slowed down because the Back buffer is always accessible for the GPU to render to, fortunately. Therefore, you don’t experience screen tearing as there is still a frame store in the front buffer for the scan, Thankfulness to the Last Rendered buffer’s inclusion.

You should notice and remember that NVIDIA Fast Sync only functions as long as the GPU is rendering at a frame rate above the monitor’s refresh rate. Suppose the GPU is rendering at a lower frame rate than the monitor’s refresh rate. Then, It means you may still experience the screen tearing.

To solve this, you will require a G-Sync monitor, eliminating the screen tearing by reducing the monitor’s refresh rate to the GPU’s rendering rate. 

How to Enable Fast Sync Using NVIDIA Control Panel

Suppose you have an assisted GeForce GTX graphics card based by Maxwell, which is GTX 960 or more latest. Then, you will be able to enable NVIDIA Fast Sync on the NVIDIA Control Panel effortlessly.

This software comes along with your graphics drivers, and you will not need to install it separately. Therefore, follow the step by step guide provided below to get this done: 

Step 1: First of all, right-click anywhere on the desktop and click on “NVIDIA Control Panel” to open up the software for enabling NVIDIA Fast sync.

Step 3: When it completes, scroll down in the right pane.

Step 4: Then, click on the option of “Vertical Sync.”

Step 5: After this, select “Fast” from the dropdown and click on “Apply” to save these settings for NVIDIA Fast Sync.

This is all you will need to do, without any doubt, to enable NVIDIA Fast Sync on your computer. Fortunately, you don’t even have to spend additional money on purchasing a G-Sync monitor as well.

Yet, if you do have a G-Sync monitor, but your GPU is rendering at a frame rate above your monitor’s refresh rate. Then, you will still face screen tearing issues until you enable Fast-Sync. 

Is NVIDIA Fast Sync Better Than VSync?

If that question has emerged in your mind, you are not alone because it is an obvious question. There are some drawbacks to V-Sync that make it less preferred. One of the most significant drawbacks that gamers face after enabling V-Sync for gaming is input lag. Input lag hinders the gaming experience of the gamers, especially when they are playing the fast-paced games. Therefore, nowadays, almost all gamers prefer disabling V-Sync.

To put it in other words, they keep it turned off or disabled as the latency could even go up to 100 ms. Regardless, with NVIDIA Fast Sync, the case is not similar because the latency gets significantly minimized and decreased along with giving a performance that is pretty close to what gamers would get indeed when V-Sync is disabled or turned off.

Does Fast Sync Work for All Gamers?

Nonetheless, Gamers will need to make sure that V-Sync will disable on all your games. Because some games have this option turned on by default. Therefore, consequently, NVIDIA Fast-Sync might not work as the gamer wanted it to be. It will easily disable or turn off by going to the Graphics or Video settings of any game.

Doubtless, suppose the gamer has an ordinary monitor with a capable GPU that’s capable enough for rendering at a frame rate above the refresh rate of their gaming monitor. In that case, NVIDIA Fast-Sync will be able to entirely solve all the screen tearing issues gamer may ever face while introducing just a minimal lag. 

Eleggible’s Final Words

We think NVIDIA Fast sync has done an incredible job by introducing its latest technology to benefit gamers who had several issues with the traditional V-Sync. 

Above all, screen tearing is an issue that none of us wants to experience, especially when it comes to gaming. Therefore, NVIDIA Fast sync becomes kind of a necessity while playing fast-paced games. So, we can have an uninterrupted excellent gaming experience.

So, to this end, we think NVIDIA’s fast sync is something that fast-paced gamers must own. To put it in another way, they all should have NVIDIA fast sync enabled in their computers while playing games.

Happy Gaming!!
