Clarification on Enabling G-Sync

Level 10
Greetings,

I am running 2x GTX 980's in SLI on a ROG Swift G-Sync monitor. I have a question about what settings I should choose to enable G-Sync rather than V-Sync.

Under 3D settings in the Nvidia CP I have V-Sync set to G-Sync under 'Global Settings'. When I look at the game profiles, they all have the global Gysync setting by default. I read on this forum that V-Sync should also be disabled within the in-game settings... is this the case, or would this disable G-Sync given that the game profile dictates that it should be the V-Sync mode.

When G-Sync is activated on the ROG Swift, the LED turns red at the bottom. My monitor LED does turn red regardless of whether I enable or disable G-Sync within game, as long as the game launches in full-screen mode. What is confusing, though, is that AIDA64 reports the refresh rate (via sensor panel on my second monitor) as 144MHz consistently, regardless of the FPS. If the FPS in game drop to 80, let's say, shouldn't the refresh rate change to 80MHz dynamically as well? Is there a way to verify that refresh rate is changing in sync with FPS?

Thanks for any info on these questions.

GSync is much better than VSync: disable VSync in games.
Nvidia drivers override game settings.
AIDA is reading your display refresh rate setting, not your active refresh rate that only happens in games. There's no way to check by number the active refresh rate, but with GSync on (red LED) it is working. You can try the GSync demos perhaps.

Thanks for the clarification.
