(Apologies if this is not the right place or if this has already been discussed.
General wisdom here seems to be that the frame-limiter should be set to "RefreshRate -3" in both the NVidia Control Panel and in-game. My theory was that the frame limiters might be "fighting" with one another, so I decided to set the limiter to "RefreshRate -3" in the Control Panel, and "RefreshRate -5" in games that support it. (Essentially prioritizing the in-game limiter if one is available). I was quite shocked to discover that all of the random stutters I had been experiencing off-and-on for the past year had completely vanished!
Anyhoo, that's all I wanted to share. Hopefully this helps somebody else!
