    From what I gather, this is G-sync without that G-sync chip. Or am I wrong?

    It's a power saving feature that's been available on laptops for a long time. You can lower the refresh rate to save power by reducing the display clock if the system is idle.

    Even if it isn't G-sync, it sounds like it could be hacked into a G-sync-like capability if the display can change refresh rates fast enough.
