Is this how G-Sync really works?

Hello All,

I've been interested in Nvidia's new G-Sync technology but have been slightly confused as to what it really does. From my understanding, it is the exact same thing as V-Sync, except that when you go below the monitors refresh rate in frames per second, it will match the refresh to the FPS.

In this case, anyone that will play CS:S, CS:GO, TF2, and any other game that requires a majority of mouse input that can easily be ran over 150 FPS will still encounter the crazy input lag that comes with it and will not benefit from G-Sync at all?

Please read this information from Nvidia:

That should help you understand what it is and does.

Also please watch this video if you are interested about G-Sync VS Freesync:

Vysnc syncs the gpu with the monitor, gsync syncs the monitor to the gpu. Gsync eliminates all the bad that vysnc has, no stuttering or input lag increase.
