Yeah full screen. It was towards the very end to be fair. 
 
**EDIT**
 
Just fired it up to test some areas. I beat the game with out using OSD. Now that I am using it. I am seeing 144+ fps in some areas.

G-sync will mostly be of benefit if your frame rate stays under your monitors refresh rate, so no need to pin your frame
rates any higher. I found in some cases depending on the frame cap used, things got real choppy and unplayable. To
save myself time and hassle, i just leave V-Sync off and never set frame caps anymore, G-Sync is a marvelous thing ! 
You might want to set V-Sync off globally in NVCP tho, sometimes G-Sync ignores V-Sync settings in-game.

FrameRate CAP is still a very marvelous tool if you're trying to not go over a certain FPS. Why would someone want that? Well for me, it's all about realism. There can still be some issues if the game is going well over the monitor's refresh rate, because VSYNC is still "off" in this case, and the game is going over the parameters of the monitor. Since you all have Vsync off, then I would recommend setting a framerate CAP. I actually was experiencing fattysgonewild's issue with the choppiness on Company of Heroes (good game btw), and once I set a frame rate target to be below the monitor's max refresh rate, issues went away.

I do. But, I had noticed playing Firewatch. I was exceeding 144+ frames. It started getting nasty with stutter and slight tearing. The second I enabled framerate target in Precision @144 fps. Smooth as butter again. In all games I can control vsync setting wise. I always make sure vsync is set to off and using Nvidia defaults. Its set to use the 3D application controlled setting. 

 
Try Witcher 3 with the FPS cap on running at 45FPS, it really is that amazing.

Yes, i know there are times where this could be of benefit, but in regards to G-Sync, i
was trying to say the same thing as dakon basically said, and to just let G-sync do its job.
I agree with you %100 as i mentioned it can be choppy aswell, if it goes above. A 144fps
cap should reign that in for him. Being a heavy FPS player, a 45 fps cap could prove 
detrimental to reaction time for me, thanks for your insight tho. I've only had G-Sync for a 
couple months, and have been wanting to engage in discussions on this topic for tips. There's
alotta different games where G-Sync could be configured in different ways to be more
beneficial in certain circumstances, we should learn them all to get the most out of them.
Later i'll give your advice a go again and pin it to 144 fps and see how it performs over time.

I am curious, why cap Witcher 3 at 45 fps?  I play at 1440p maxed out including hairworks and my PC maintains between 85 and 105 fps.  I guess that would mean I could cap it at 80, but why?
 
144 fps in Firewatch?  At what resolution?

1440p with the monitor I am using in my sig. It will easily break 144+ in certain areas while playing using max settings. 

In movies, the usual is 30 fps, but there are instances where they will produce films with 48 and 60 fps, which changes
the over-all perceived experience. I'm thinking stalinx20 is referring to this kind of idea, but in a gaming situation.

I tried it all on Witcher 3...60fps, 90fps, 120fps... I like realism in games, and with GSYNC at 45FPS, It's really good, but not all games are good at 45, lol. I have everything maxed out (yes hairworks included). It's just me really, everybody has their own opinions, flavor(s), and what not. Batman Arkham Knight is another good one. Seriously, if you have a GSYNC monitor, try it.

I can't bring myself to go down to 45 fps, lol

I feel ya! Lol

Ya pay good money for fast frame rate and limit it??

Like buying a muscle car for 30-50k and drive in the right lane doing 25mph like an 80 year old man with a hat!

Not this guy!

Yeh, well, stalinx20 might be onto something there in regard to The Witcher 3, but its certainly not a good
idea for the kind of games i play, so i won't be doing this either. My suggestion is, if you have to use frame
caps to deal with tearing and choppy game-play, then set it to 143fps while in 144hz. Otherwise, let it run.
