There was a thread recently with the nvidia 3D settings you should have and I forgot to bookmark it... I've looked for the thread itself and have searched for it but all threads i can find are years old...
If anyone could help it would be appreciated:)

It's sad I can't find a good guide properly explaining Pre-Rendered frames.
but 1st what to do.
Open Nvidia Control Panel
Under "3D Settings" select "Manage 3D Settings"
Now you can either do this Globally or for a specific Program (or game) if you select by program you will have to select the one you want to change via the drop down list or you may have to add it.
Either way under "Settings" you will find "Maximum Pre-Rendered Frames" for most FPS games set this to 1. (you can also do this globally if you want)
Now for what Pre-Rendered frames does (to my understanding which really isn't that indepth on this)
Pre-Rendered frames when set to 3 draws 3 frames before releasing 1. Which in practice means you have higher input lag (how much depends on your framerate)
Formula = (1000 / FPS) * PRF = Input Lag in milliseconds ( this is assuming a constant fps plus I might be slightly off on this)
EX1.
Pre-Rendered Frames = 3
FPS = 200 (assuming constant)
Input lag = ~15ms
Input Lag added by PRF = ~10ms
EX2.
Pre-Rendered Frames = 3
FPS = 100 (assuming constant)
Input lag = ~30ms
Input Lag added by PRF = ~20ms
Some of you might ask why you would want to have PRF = 3 or at least anything higher than 1. The main point behind this is that if there's a sudden FPS drop, say you have 90fps while playing your favorite RPG and then you suddenly drop to 20-30 having those extra Pre-Rendered frames really helps to smooth that out. In some cases having PRF higher means you'll have a slightly higher overall FPS.
If anyone knows more on the topic feel free to correct me.
-edit-
Personally I have global setting PRF = 1 and I individually change games to higher PRF if I have a lot of FPS fluctuation (Witcher 3 and Ark Survival Evolved I have PRF = 2 and PRF = 3 respectively)
