No, I mean V-sync ON in nVidia settings and OFF in-game. I know it sounds wrong but check out this very informative link from Blurbusters to see optimal settings for a g-sync monitor: https://blurbusters.com/gsync/gsync101-input-lag-tests-and-settings/14/
In fact, from personal testing on games that exceed 165hz (my montior’s refresh rate), turning on vsync in the nvidia control panel eliminated my stutters (rocket league).
