Nvidia G-sync and Dolphin

[TSM]

I was thinking about buying a g-sync monitor when they become available. I was wondering if there had been any speculation about whether dolphin would function with g-sync. From what I gather g-sync only functions when games are rendering full screen. I'm mostly interested in it working with dolphin because this would potentially allow dolphin to scan 30 fps games at 30 hz (the Zelda games for instance). This should result in a massive reduction in judder. I'm just wondering whether dolphin is actually running at 60 fps when rendering 30 fps games. I can't imagine this has been given much thought since native 30 hz scanning hasn't really been an option since we left CRT technology behind.
