What is G Sync?
So What is G Sync (G-Sync) actually is a question many gamers have been asking. G Sync is a technology developed by a tech giant company Nvidia. Nvidia is very well known for making the best GPUs (graphics processing unit) out there. They developed G Sync to help with a problem called screen tearing – an issue which happens when Monitor tries to show multiple frames information on a single screen frame. The alternative to G Sync is FreeSync. Similar solution developed by competitor AMD. The main difference between G Sync and FreeSync is that FreeSync works only on AMD GPUs and G Sync only on Nvidia GPUs. Another issue is price. G Sync screens are usually several $100 more expensive than their FreeSync alternatives.
What is Screen Tearing and how does G Sync solve it?
Most standard monitors operate on one single refresh rate, be it 60hz, 100hz, 144hz or something else. It is just this refresh rate at all times, without any variety. However GPU in your computer does not operate in this way. GPUs are trying to output the maximum number of frames per second their performance allows them. That can sometimes be faster than the refresh rate of the monitor, and sometimes slower. And this difference in refresh rates is causing screen tearing.
As mentioned, screen tearing is when the monitor is trying to show picture from multiple frames on a single screen frame. The reason for this to happen is when there is no synchronization between the feed from the GPU with the monitor’s refresh rate. So monitor is maybe trying to show 100 frames per second, but GPU is feeding it with image quality of 120 frames per second. When there is mis-mach in these frame rates, the tear line moves across the screen proportionally to the difference between these frame rates. The screen tearing has been pretty common when watching movies, or playing video games, and it is still an issue.
For videos, screen tearing is fairly easily solved by software improvements. One of the most common solutions is called multiple buffering. This works by using more than one buffer to hold data, so that there is complete data always available for the monitor to show. However this solution is not good enough for GPUs and video games and that is where G-Sync comes in.
Another way of fixing the issue of screen tearing is vsync – vertical synchronization. With this method, the GPU is programmed not to push any more data to the monitor until the screen is done with its current refresh cycle. This happens during so called vertical blanking interval. But this solution is also not easily used in PC Games, and that is where G Sync comes in.
The G Sync actually adapts the refresh rate of the monitor to the refresh rate of the video stream coming from the video card. For this reason, this is not just a software based solution like VSync or Multiple buffering. It is a combination of software and hardware solution. That is why a specific G Sync compatible monitors are needed for adaptive refresh rate.
In addition to standard syncing of frame rates, Nvidia built a collision avoidance system. This is to avoid the event of the next frame being ready and sent to screen while duplicate is being still drown.
The actual hardware module which is in the monitor carries all the functional parts and it has 768 MB capacity. The magic is in monitor’s ability to actually output variable refresh rate. That means that the monitor is constantly adjusting the refresh rate to the GPU refresh rate. In order to use G Sync, you must own Nvidia GeForce GTX 650 Ti Boost GPU or higher and of course the G Sync compatible monitor.
How effective is G Sync
It is a really great solution for removing screen tearing and it works flawlessly. The effectivity of G Sync depends on the other hardware on your PC and what kind of games you usually play. G Sync helps with synchronizing the monitor and GPU refresh rates. However that is not really necessary to do if you always have the best GPU on the market. If you buy new top-end GPU with every new Nvidia release, than you don’t really have to worry about screen tearing.
However if you have a mid-tear GPU, and want to play high paces games on high refresh rates over 100hz, then you should give G Sync a thought. For games like Fortnite, Rocket League, Overwatch or Apex Legends, high refresh rate is crucial and can significantly improve your results and help you reach higher ranks, higher kills, more goals and anything else you are seeking. For these kind of games, and if you play on mid-tier GPU, G Sync is very effective.
If you are more of a strategy game player, and can’t resist making another turn in Civ V (or IV, or VI), or you are Heroes addict, then save your money for new games and DLCs. For you the G Sync is not going to be too effective.
Is G Sync worth it?
G Sync is a pricy solution. The monitors with G sync are usually $200 more expensive than monitors without any adaptive technology, and $100 more expensive than FreeSync monitors. So whether it is worth it depends on how big of gamer you are and what kind of games you play which we mentioned before.
It also depends on what GPU you have. If you already own AMD GPU, then it is not worth it to buy Nvidia GPU and G Sync monitor just to have G Sync. In that case you should start looking at FreeSync, which is also much cheaper. The reason is that G Sync is not compatible with any AMD GPU.
Does G Sync increase FPS?
The short answer is – No. G Sync is fully focused on removing screen tearing, not on increasing your FPS. It’s whole purpose is to synchronize the refresh rate output of your GPU, with the refresh rate of the monitor. It helps optimize the performance. But in no case it can make your GPU more powerful and produce more frames.
However, thanks to removing screen tearing, your gaming experience will improve significantly. The gameplay will feel smoother and better. And so on the surface it gives you the feeling of better performance, less stutter and no screen tearing. But it can do all of that not by increasing the FPS, but by syncing it between two pieces of hardware.

G Sync on FreeSync monitors
In 2019 gamers got some good news from Nvidia. The company announced that it has certified some FreeSync monitors to be used with Nvidia G Sync GPUs. This is a huge news, since FreeSync monitors are usually cheaper than FreeSync. This will make the tear free technology more accessible to gamers.
From Nvidia point of view, it also makes sense, since now customers don’t have to buy AMD GPU to be used with their FreeSync monitor, but they can buy Nvidia GPU and use FreeSync like this.
