So i dont really know what has happened, as this seems really bizarre.
G-sync doesnt work as properly intended anymore, i get the lack of screen tearing, but if my framerate isnt a variable of the max refresh rate i get judder from the framerate not being in-sync, which is one of the benefits from G-sync, i havent used it in over a month but it used to work AMAZINGLY for games like Sleeping Dogs and Tomb Raider, now it doesnt work atall, i get the lack of screen tearing but now it isnt even smooth reaching the max refresh rate.

Happens on every game, i have no idea what to do to fix it, the only thing i have noticed as of lately is the fact that my screen flickers a fair bit on some blank pages at the bottom, but no idea on that.

I run the Acer XB270HA 27" G Sync Monitor. an i7 4790k @4.5ghz, x2 GTX 970, 16GB Hyper X and x2 1TB SSD x1 250GB SSD (850 pro)

Anyone have any idea what is up, maybe it is Windows 10 or? Id love to start using g-sync properly again.

(It happens if SLi is turned on or off. Or even uninstalled the second card)
(And sorry if this is in the wrong section!)
 
What is VSync set to in the 3D Settings part when GSync is enabled? Also try only enabling GSync in fullscreen mode if you have the new fullscreen + windowed option selected.

It auto selects to Vsync on (I will try it with turning that off)
And i only run it in the fullscreen option, let me just go test the vsync off option.
 
VSync off with GSync enabled should work exactly the same as GSync except that when you are capable of rendering a framerate over the refresh rate it will work as if VSync/GSync is off until your FPS drops below the refresh rate again and you'll get tearing while its rendering faster than the max refresh but it will render the next frame as fast as possible (not an option you'd really want with GSync - but some competitive players prefer that config).

Turning the V-sync off feature does make it a lot better, i just dont remember it being so uneven, like the controller/mouse gets caught looking around sometimes.

I'll probably just stick to still using V-synced 60fps, i just remember g-sync being a lot better for some games.
 
Could be a number of things but first up try disabling SLI and then see how it is.

There are quite a few games that have issues with SLI and Gsync. However sleeping dogs and Tombraider are not games that have issues from my testing. In fact they are 2 of THE best games that demonstrate the smoothness of Gsync and SLI for me. They should be smooth as silk.
It sounds like they used to be, but now they aren't? It's a long shot and a really basic thing but just try re seating your SLI bridge, or if for some odd reason you've swapped your cards round, put them back how they were.

Like i said, i completely remove one card from my system entirely and its still there.

Ah sorry bud, Friday night glaze:)

Hmm. That is very odd then. You've obviously tried both cards separately, on their own yes? And in a different PCI slot, if possible, just to rule a few things out?

Other than that, no idea. If you rule out the hardware being the issue, got to look at software/ drivers I guess.

It's definitely better not in SLI but regardless of either card being the main or any pci slot they both dont do it well.

Im trying to see if its software but im on a fresh install with only all the needed drivers for each thing so it shouldnt be that either.

I'll keep looking into it.
 
Are you saying the ONLY thing you've changed on your system is upgrading to Windows 10?

If that's the case then it would seem the most likely culprit. Must have affected something?

You sure you haven't made any changes at BIOS level, tinkered with any CPU settings perhaps?

I'm something of an expert on SLI stutter problems and GSync. It's a bit of an obsession of mine to get certain games running as smooth as possible. SOme just don't, some require bizarre tweaks and tricks.

However, the thing that ALWAYS guarantees super smooth performance (in terms of zero judder/ jitter) with Gsync on my system is to disable one card and not run SLI. Yes the framerates are lower so it's not making the most of the Rog Swifts high refresh rate, but sometimes it's still 'smoother' and some games run fast enough anyway on one 780Ti.
So, if running one card only isn't helping for you there's definitely something not right.

Only thing i've done is upgrade to windows 10, still run the same pc i did when i got it apart from adding SLi.
I think maybe my module is broken? I cant see any other reason why it wouldnt work properly. That or it's Windows 10.
I pretty much just have an issue where i get no screen tearing, but regardless of the framerate its never smooth (so in my opinion the refresh rate isnt dynamically changing anymore.

Watched your YouTube clip.

Ok, something is royally ****ed there! In a way that's better than a minor issue as its so pronounced and obvious that there must be something seriously wrong.

If you disable gsync in the control panel, I'm presuming you don't get these chronic pauses at all? If so then you could assume there's nothing wrong with your GPU.
You need to totally clean out your drivers though and try again. Use DDU.

If you're still getting this issue after that then perhaps the gsync module in your monitor is physically faulty.

Fortunatly for me i have a second rig, a guest rig, not as powerful but still great enough to run games, i7 2600 @ 3.4, 8GB Samsung Green, GTX 680 Power Edition etc.

And it works on there just fine, no issues, so it is definitely an issue somewhere in this rig, the old rig still runs Windows 7. Different chipset and mobo etc.

But the moment i turn off g-sync on my main rig that issue happens again, so we definitely know its somewhere in my rig driver wise doing this, so im going to do complete driver wipes today hopefully.
 
well, doing a fresh driver install fixed that issue, but my other still remains where varying framerates are not smoothed out. It feels like playing with an fps thats uneven to the current refresh rate regardless. Which gsync didnt seem to do to me before.

So i dont know what to do abut that, it sucks because i'm waiting for Battlefront and i want to use gsync in that and now it's looking like either it doesnt work properly anymore or its just overrated. But i've had it for almost a year now.

So, just to be clear, you have tried your Gsync monitor on your second rig, and gsync works fine on that, and you see none of these issues?
