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.

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.

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.

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

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!

First off, I don't have a 1080, I have 980 SLI, which smokes a single 1080... sooooooooooo..., and you still wonder why I do it. Again, realism, but only in certain games. otherwise 140+ 

Second, that's a very poor analogy. The true analogy is when you are running a very complex 3d rendering app and trying to continue to achieve the certain FPS you're wanting without it tanking or dropping below a certain FPS, or pulling a very heavy trailer and still maintain the horsepower at that same speed. THAT"S the correct analogy. Or, something else... You have all that "horse-power" but you're using it for apps that require hardly any power... Total waste.
 
Do you have a GSYNC monitor? If you did, then you would know that 45 still feels like 90 if you think about it. I also do not run all games at 45, which it appears you missed. Once you have GSYNC, you'll never go back, ever. Games are not all about FPS unless you're running e-peen battles (Keep rocking that heaven benchmark , because nobody cares lol). The other reason is by setting it at 45, i don't have to worry about any dips that might occur in those 2 games. Once the FPS is very smooth (which Gsync achieves) then FPS is irrelevant, due to fast response and low latency, but below 40fps there is a clear difference and I will never go below that on witcher 3 or batman.

Excuse me but I've I've got a 27" asus g-sync monitor that does 164fps. I've had 2 Gigabyte G1 Gaming 980s in sli for the past 1 1/2 - 2 years or so and i've since moved to 2 1080 evga classifieds in sli on the same monitor.

Yes if the frame rate dropped into the 45 range it would feel like a stuttering mess! Anything below 50 is not good on g-sync..I know cause I've had recently ran a single 980 in the system in between 1080s as I've had the zotac amp,pny and evga fe cards and evga ftw hybrid and now the classified 1080s.

Btw. My 7 year old is getting my old (current) rig with my 980 sli while I upgrade my whole rig to go along with the new classifieds.

I also bought him a new 24" 1080 144hz monitor for his pc since the smaller 4gb ram on the 980 will run best with at 1080.. always gave me issues at 2560x1440 on my monitor with the 980sli. Hate turning down settings just to keep the frame rate up. 8gb vram is what you want for 1440.

Let's not make this a pissing contest, 'cause what you do on your PC is on you, and you only. Second, what you just mentioned in bold is completely false. It works from 30-144hz. it's below 30 that causes the problems, and over 144. I'm not even sure why you brought up your other systems, nobody cares.

Since you do have a Gsync monitor, then you know very well what Gsync is capable of, or you should know at least. It looks like you haven't really experimented much with it. But, game on at 140+ if it makes your gaming experience that much more enjoyable, but I won't judge you like you judged me. Game on.
 

G-Sync is capable of refresh rates that range from 30Hz to 144Hz, while the FreeSync spec is capable of refresh rates that range from 9Hz to 240Hz. That doesn’t mean that you will find monitors with a refresh rate range of 9Hz-240Hz but it means that monitor makers can make monitors with any range in mind that falls between 9Hz-240Hz. FreeSync monitors out right now feature a variety of ranges.

Notes from Nvidia website:

For enthusiasts, we’ve included a new advanced control option that enables G-SYNC to be disabled when the frame rate of a game exceeds the maximum refresh rate of the G-SYNC monitor. For instance, if your frame rate can reach 250 on a 144Hz monitor, the new option will disable G-SYNC once you exceed 144 frames per second. Doing so will disable G-SYNCs goodness and reintroduce tearing, which G-SYNC eliminates, but it will improve input latency ever so slightly in games that require lighting fast reactions.

In other words, bud, once you're passed 144hz with GSYNC, it's useless. Good luck. Hence the reason for Vsync and/or Frame-rate target.
 

AHowes I brought that up cause he stated that his 980sli will smoke a single 1080. But it's only got 4gb ram. Fine for a 1080 monitor but for some games that small vram will choke on it at 1440.
Btw.. I'm not the first guy to claim g-sync stutters under 50 fps. Could be just marketing and they want you to believe it's fine or just drivers but no thanks.. if it was great then I guess I would of never bought another 980 back when.
