What Is G-Sync And Is It Worth It?

WHat is G Sync and is it worth it

If you have been searching the market for a new gaming monitor you have probably come across the term "G-Sync" when looking into the specifications. Not all monitors come with this technology and, in general, the G-Sync module adds extra cost to any monitor it features on but what is G-Sync, and is it worth it?

G-Sync is an adaptive sync technology created by the graphics card giants Nvidia. The technology was created to help prevent screen tearing and it did this by synchronizing monitor refresh rates to graphics cards frame rate, ultimately ending in some silky-smooth gameplay.

In this article, we are going to go over what G-Sync is, its pros and cons, what alternatives are out there, and ultimately find out if G-Sync is worth it for you!

What Is G-Sync And Will It Help You?

V-Sync was around first to try and help with screen tearing and it did this by capping the frame rate of the monitor to match your GPU's output, but if it dipped you would still witness some stuttering. G-Sync was originally designed to be used with V-Sync however Nvidia soon allowed people to turn this option off. The G-Sync module allows for a dynamic refresh rate that matches the output from your GPU, much like V-Sync but it takes care of the dips as well.

G-Sync updates the screen exactly when the frame is finished and wants to be output by the GPU. The refresh rate is the maximum frame rate used by the G-Sync module and with G-Sync you shouldn’t get any lag or noticeable tearing. The reason for synchronizing is down to refresh rates from both your monitor and graphics card, with the monitor working at a fixed refresh rate and the cards refresh rate fluctuating often resulting in a screen tear.

So the bottom line is if your GPU is creating frames at a lower rate than your monitors refresh rate you should experience some stuttering and if it's operating faster then it can show the next frame too quickly resulting in a tear.

G-Sync: Pros

Unlike V-Sync which caps the frame rate to match the monitor's refresh rate, G-Sync allows the monitor to work at a variable refresh rate matching the GPU and ultimately eliminating the chance of tearing and lag, as it accounts for dips and peaks in performance.

Let's put this into a real-life scenario. So, if you are playing a demanding game with G-Sync enabled and achieving 100 fps, your monitor's refresh rate in real-time is matching that frame rate. Let's say you come to a part in the game that is even more demanding on your GPU and you witness a much lower FPS, then it shouldn't be an issue as your frame rate is matched yet again by the module.

G-Sync: Cons

Being a proprietary technology, the G-Sync module can be considered an expensive luxury as the G-Sync scaler replaces the standard one in a monitor. Other sync technologies such as Freesync are hardware-software solutions too and are normally a cheaper option due to the scaler being manufactured by multiple different companies.

The addition of G-Sync can sometimes add hundreds of dollars to your bill but as of last year, Nvidia began to release drivers that would enable their GPUs to work with certain adaptive sync and Freesync monitors. This now makes G-Sync a more affordable option and is a brilliant move from Nvidia even if it took them a little while to get here.

Another downside to G-Sync is it will not work with AMD graphics cards so if you have AMD or plan on going down this route, do not buy a G-Sync monitor. G-Sync only works with Nvidia cards but the monitor would still work on your AMD setup meaning you would have paid a premium for no extra features.

Alternatives

AMD graphics cards use a different adaptive sync technology developed by themselves called Freesync. Freesync, unlike G-Sync, is open source so monitors don't require a proprietary module which creates a competitive market and reduces the cost. Freesync is often used in more budget monitors which drive the price down and pass on the savings to the consumer (you).

It’s worth noting while G-Sync locks the frame rate to the upper limit of the monitor Freesync can bypass this and give you higher frames. This would result in some tearing as your frame rate and refresh rate wouldn't match but would keep input lag very low. Some Freesync monitors are now compatible with Nvidia cards giving yet another option to gamers.

A quick fix to the tearing issue could be to turn on V-Sync in your settings. V-Sync is otherwise known as vertical sync and caps your graphics cards frame rate to the refresh rate of the monitor. This may deal with the tearing issue in the same way G-Sync and Freesync do however V-Sync doesn't deal with the dips in performance and you can still get a ‘stuttering’ effect.

Is G-Sync Worth It?

What is G-Sync and is it worth it? Now you know but obviously whether it is worth it depends on your preferences and budget. If you have money to spare and want the best ‘future proof’ setup you can get, then buying into G-Sync is a smart investment, as this technology becomes more widely available over time.

On the other hand, you may not want to put up with the input lag V-Sync can cause and would prefer a cheaper alternative to G-Sync, then Freesync would be your best bet. If going down the Freesync route, make sure to have an AMD graphics card or a monitor with Freesync that is compatible with an Nvidia card.

This sort of technology is great for those that hate tearing and want to run demanding games smoothly but if you're just into hardcore FPS or low spec games, then this increase in your costs is probably not needed.

    i have a free sync AOC C27G1 27″ Widescreen VA LED Monitor and it works in G Sync mode with my nvidia GTX1070. This is due to the Nvidia software/driver improvements. I might add i brought on amazon new for £218 Sterling, very reasanable indeed.
