GSync and Frame Limiters

Hi! I have been recently getting back into SHAR and noticed some issues with the framerate. Using the limiter built in to the latest Mod Launcher, the framerate seems to fluctuate from 60-65 and it stutters frequently. I tried using RTSS instead, and while it was slightly better, I encountered clipping issues with cars. I think GSync may help with the stuttering issue, but it does not activate when in game - I enabled the "GSync indicator" to check and it did not appear in game. If anyone has any suggestions it would be greatly appreciated. Thanks!

EDIT: I have no clue what I did, but it looks like limiting the fps in RTSS to 60 and disabling fps limiter in the Mod Launcher fixed it, or at least made it much much better.

EDIT 2: Gsync is definetely not being enabled - in the Nvidia control panel I saw no difference between "monitor technology" being set to Gsync or fixed refresh.
