Problematically, graphics cards don’t render at fixed speeds. In fact, their frame rates will vary dramatically even within a single scene of a single game, based on the instantaneous load that the GPU sees. So with a fixed refresh rate, how do you get the GPU images to the screen? The first way is to simply ignore the refresh rate of the monitor altogether, and update the image being scanned to the display in mid cycle. This we call ‘VSync Off Mode’ and it is the default way most gamers play. The downside is that when a single refresh cycle show 2 images, a very obvious “tear line” is evident at the break, commonly referred to as screen tearing. The established solution to screen tearing is to turn VSync on, to force the GPU to delay screen updates until the monitor cycles to the start of a new refresh cycle. This causes stutter whenever the GPU frame rate is below the display refresh rate. And it also increases latency, which introduces input lag, the visible delay between a button being pressed and the result occurring on-screen.
Worse still, many players suffer eyestrain when exposed to persistent VSync stuttering, and others develop headaches and migraines, which drove us to develop Adaptive VSync, an effective, critically-acclaimed solution. Despite this development, VSync’s input lag issues persist to this day, something that’s unacceptable for many enthusiasts, and an absolute no-go for eSports pro-gamers who custom-pick their GPUs, monitors, keyboards, and mice to minimize the life-and-death delay between action and reaction.
Enter NVIDIA G-SYNC, which eliminates screen tearing, VSync input lag, and stutter. To achieve this feat, we build a G-SYNC module into monitors, allowing G-SYNC to synchronize the monitor to the output of the GPU, instead of the GPU to the monitor, resulting in a tear-free, faster, smoother experience that redefines gaming..
NVIDIA G-SYNC is so smooth and so fast, that testers have found themselves overshooting and missing targets because of the input and display lag that they have subconsciously accounted for during their many years of gaming.

Some of you are kind of missing the point. If you ever drop below 120fps ever you'd see an improvement with this tech. For those talking about if it's better than being locked at 120hz, also if you ever go above 120fps you'd also see an improvement.
Even at 30hz, shows up in this link.
basically whenever your gpu finishes drawing a frame it'll refresh the lcd, this is pretty rad.
This actually puts LCDs on par with CRTs imo (with respect to refresh and latency)
Also instead of waiting for the locked 120hz / 60hz refresh, it will immediately update which could have a lower latency than even CRTs.

Will G-SYNC provide benefits to people already using 120+ Hz monitors?
No, because none of those monitors have the G-Sync tech in them. Want to use it? Buy a new monitor.
But is G-Sync even necessary if you have a 120 Hz monitor? I don't use V-Sync and I don't get tearing so would G-Sync even offer any advantages?

Who is still making or selling CRTs?
The first brand on the Chinese Mainland that wants your business is CANDON...still making 21" Trinitron knock-offs for about $50 (or less) wholesale. Combine this url:

Mostly for Security Camera Monitoring, etc. Buy 50 and have plenty extra.
This... this is trolling, right?
Pretty sure he was trolling from the first post. But I love how you went and did all the research to completely dismantle his argument.

Would this equate to lower framerates not looking so shitty as well, considering the refresh rate is matched?
Sorry, I'm no techie
I don't think the monitor would sync to lower framerates than its default refresh rate (likely 60hz.) It'll just run at 60hz unless your fps goes above 60, then it just scales up.

Dearest Beamer, aged veteran of gaming, whom I've watched flourish on these forums, both of those stated assertions are incorrect and I'll assume you were just making a friendly point since you know better.
I leave it to the astute reader to generic-internet-search why, but here's a hint..LCDs biggest advantage (larger size) only magnifies their many visual drawbacks compared to CRTs. Though large screens are nice..widescreen, etc.

Except thats not a problem for 99% of PC gamers.
Guessing you missed that while Steam OS announcement, huh?
And how many still use WinXP.
Or i never left reality
