Adaptive Vsync vs G-sync

Solution
To clear the small confusion,
GSync/FreeSync is arelatively new technology which is far better than VSync and adaptive VSync.
Adaptive VSync is only VSync but slightly modified
GSync is more or less an overpriced FreeSync.

About the more cheaper solution to GSync (aside from VSync or adaptive VSync):
Unfortunately, if you have nVidia GPU, there is no cheaper solution than GSync.
Freesync monitors work only with AMD cards and not compatible with nVidia cards (also vice versa for GSync).
Same reason people that drive Ford/Chevy/Dodge vehicles like to bash people that drive Dodge/Ford/Chevy vehicles.

As far as I can see, both pretty much do the same thing. One (G-Sync) is a proprietary technology that adds to the cost of the monitor, and one (FreeSync) is an open standard and free to use.

Unfortunately, the two are not compatible with each other, so if you want that technology today, and you have an Nvidia graphics card, G-Sync is your only option. This is a negative for the industry. But Nvidia seems to be trying to split the graphics markets into an either or market. At this rate, we will reach a point in the not too distant future were you may well need to buy 2 video cards, one from Nvidia and one from AMD to be able to play all games well. All because Nvidia refuses to play nice and share the inventions it comes up with, while AMD makes them available to everyone by making them open standards.
 
i dont think he was talking about freesync but Adaptive Vsync which is nvidias slightly enhanced version of vsync... or he's gotten himself confused...

He was talking about Adaptive V-Sync and not display port adpative sync. It can be confusing for those that never heard about nvidia adaptive v-synv (which if i remember correctly nvidia introduce with GTX780 although the feature are not limited to 780 only)

@OP

nvidia has play a lot in regards to smoothness, tearing and latency. G-Sync was supposed to be their ultimate solution for it. As for adaptive vsync vs gsync while they try to solve the same issue (latency) gsync also solve the smoothness of a game at low frame rates.
