Needed to reply to this topic again. I've been testing the adaptive v-sync feature with various games including Skyrim.
I'm beginning to conclude that my original advice is incorrect. Meaning that turning OFF v-sync and turning on JUST Adaptive V-sync doesn't work-- at least using nvidia inspector. For instance, using FRAPS and testing FPS with Skyrim, SWTOR, Witcher, some other random games, with vsync off and adaptive v-s ON, I'm going way over my monitor's refresh rate of 60 FPS. This leads me to believe that Adaptive V-sync is a complementary functionality and, in order for it to function, vsync itself still needs to be ON. Now the important point of this is that I'm using nvidia inspector to do this, and the VSYNC setting is a separate line from the Adaptive VSYNC setting, whereas in the nvidia control panel, it's a single line. Perhaps that single line sets both parameters whereas nvidia inspector splits them out. This may be an important distinction for those of us using that tool for our graphic options needs.
If anyone else wants to weigh in on this, I'd appreciate it. Mainly because now I'm wondering if in-game vsync is ENOUGH to engage adaptive v-sync, or should we be turning off in-game vsync (ipresentinterval in Skyrim's case) and forcing it on, in nvidia inspector. Not sure.
TLDR: If using nvidia inspector to get adaptive vsync. Turn ON Vsync. Turn ON Adaptive V-sync (Change option to Adaptive)
Cheers,

EDIT/UPDATE: A ha. I see. So I used nvidia control panel to turn ON Adaptive Vsync. Then I went into nvidia inspector to check what changed and sure enough. Adaptive V-Sync setting is on "Adaptive," as expected and in addition, VSYNC was set to "Force On."
Hope that helps y'all.
