i just rebooted my pc with an old hd monitor at 60hz, running aco had absolutely no stuttering and looked fine at 60fps 1080p. so i guess the problem is with the monitor?

That's what I think. However, if you can find a way to verify it by getting a computer shop to test a different Gsync monitor with your GPU that would be great.

i decided to reboot after with the acer x34 at 1080p 60hz, the game ran fine but i noticed a tiny bit of stuttering, this could be because its a larger monitor so looks less smooth, or i couldve been getting these on the other monitor but just not visible due to size.
i then activated g sync at 1920x1080 60hz and thats when the problems start... the stuttering etc like in the first post

That's why you need to try test it with a different Gsync monitor. Also, are you using the display port cable that came with the monitor? You could swapping the cables and see if it still does it.

yes im using a custom cable

What cable are you using? Only some are certified display port cables and others could cause issues.

Have you got the factory cable that would come with the monitor, not a custom one?

no i dont have the factory one

im using a bizlink cable

That is not on the list of certified cables and may be causing issues. Here is a list of certified cables, sorry wrong link here's right one:https://www.displayport.org/product-category/cables-adaptors/?ps&pcat[0]=8k-cables&pcat[1]=cables-connectors

The 8k cables conform to new standard and will work with displayport 1.4 and HDR and higher resolutions so are more future proof: http://www.pcgamer.com/dp8k-displayport-cable-certification-for-8k-displays-arrives/

and here is more info:https://www.displayport.org/cables/how-to-choose-a-displayport-cable-and-not-get-a-bad-one/

Try buying a certified cable and see if that solves your issue before doing anything else.

If your going to buy another DP cable to try then just buy the amazon basics one for a £5.

the only ones i can find on amazon are amazonbasics, techrise, and rankie cables none of which are the 8k ones, do you know a good place to buy them?

It doesn't have to be an 8k one if they are in short supply. It just has to be on the list, it would be better if it were 8k but it's not necessary. I'm not sure the 8k ones are even sold in the UK yet as standard is very new.

I've heard good things about the startech ones. The amazon basics one is not on the list. Like this one:https://www.startech.com/uk/Cables/Audio-Video/DisplayPort/displayport-cable-2m-certified~DISPL2M

Let us know whether the new cable fixes the issue.

Very sorry to hear that. Hopefully, they will have another Gsync monitor to test with. Good luck and keep us updated.

Have you ran firestrike or other benchmarks to make sure your card is performing as it should? If it's getting the scores it should, have you tried formatting with fresh install?

I would love to know the outcome of this. I am experiencing exactly the same issue as op. I also own an x34a and a 1080ti. When I launch the pendulum demo, its smooth for a second then its choppy then its smooth, this is between 35fps - 60fps, and running in fullscreen. Its as if Gsync keeps turning itself on and off and vsync takes over when it shouldn't.
I did a clean install of windows just recently and even with no apps running in the background it happens.

Op, do you also see excessive overshoot when it becomes stuttery followed by no overshoot when its smooth again? This is what happens when I see a stutter.
