Hey,
I suggest you learn when and where to use the following:
1) Adaptive VSync
2) Half Adaptive VSync
3) VSync Off
Before the example, please note:
a) VSync off is often unacceptable due to SCREEN TEAR. It's up to you how much that bugs you.
b) VSync on causes STUTTERING if you can't achieve the refresh target (i.e. at least 144FPS for 144Hz monitor).
So...
This is why Adaptive VSync exists.
Example:
Problem- can get about 90FPS average in a game, screen tear sucks, but can't get to 144FPS all the time without dropping quality below acceptable.
Solution- force on Half Adaptive VSync
1) Start game
2) VSync OFF
3) FRAPS ON (or Steam FPS tool)
4) Tweak resolution/settings for optimal until you rarely drop below 72FPS
5) open NVidia Control Panel
6) Manage 3D Settings
7) add game
8) select "Half Adaptive VSync" and SAVE
9) Open game and observe FPS is locked to 72FPS
???
Basically the game now toggles VSYNC ON and OFF as needed. You just need to adjust the game settings to a position that's optimal for you, depending on how bad the screen tear is. If too much, drop the settings a bit to raise the average frame rate.

This also works with RadeonPro using Dynamic VSync.

None of this is needed with GSync or FreeSync.
