I want to play witcher 3 in 4k :(

You're in the minority then. I did get the flickering issue on release but there's no stuttering o.O It's a good experience playing Witcher 3 at 4k for me, and I certainly don't struggle for 30 - most of the time I clear 60 and that's with everything but AA on ultra (and one of the vegetation viewing options, can't recall which).

Well that's what I would have expected but i'm certainly not the only one. I've read on other forums people having the same issues with stuttering. I have no idea whats wrong with it other than the drivers. It's fine when crossfire is disabled but obviously half the frame rate. Granted i'm on 290s not furys but still. It gets high fps when I put it on my 4k samsung monitor (60hz) but the stuttering makes it unplayable. It's even the same on 1440p. This is after a clean install of win10, 4.5ghz i7 and ssd. Other games like battlefield run fine in xfire tho.

Odd. Is Windows 10 the commonality between you and the others getting it? I run windows 7 and it's fine, it was fine (although not acceptable framerates) on my 7970s at 4k as well -- It was perfect at 1440p on my 7970 xfire, no stuttering just the flickering issue for the first week or so before driver update.

I'm not sure what the others were on. I had the same issues with Win 8.1 aswell. I've seriously tried everything to try and fix it that I have found on forums for configs ect. Nothing has resolved the issue. Really annoyed tbh as i'm now on second playthrough with terrible performance, great game tho just ashame amd suck.
 
Drivers at 15.7.1? Tried earlier?
Any overlays running? Sometimes overlays, even the steam one, can cause issues.
Beyond that, I'm out of ideas for you D:

Tried pretty much everything, except installing win7 lol, I've pretty much had enough of it now. Gonna upgrade gpu in a few months and just get an nvidia. Just checked out the amd support forum, there are a lot of people with Witcher crossfire issues. Seems to be 290 and 295x. Nothing is getting done tho, no comments from amd. It's been out a good while now, should have been addressed.

Thanks for the suggestions tho :)

They use just over 8gb of VRAM per card as the memory is mirrored.

A pair of 970s may struggle a bit at 4k.

For a pair of cards going from worst to best IMHO would look something like this below

GTX 970s, 290Ps, GTX 980s, 290Xs (4gb), 290Xs (8gb), Fury Ps, Fury Xs, GTX 980 Ti's

Is this the thread we chatted on this morning mate? I can't find all the posts we exchanged?

I cannot notice any difference. You got really good eyes there ;)

The whole point of AA isn't to smooth out the jagged edges? And a panel packed with 8M pixels hardly reveals them.

Jaggies are pretty much eliminated with smaller (<40") 4k displays, but they are not the only type of aliasing artefacts; thin objects like wires and hair exhibit pixel-popping without AA. It's not a big difference at 4k, but it still looks better with AA.

trust me I am not shooting from the hips :D

I owned a gtx 970 sli setup and tried all the latest games on it. You will do just fine at 4K with GTX 970 sli as soon as you turn the AA off (dont know why anyone will use AA at 4K). Plus for GTA5 you can turn down a few taxing settings like soft shadows and draw distance, etc. Rest can be pretty much combination of ULTRA/HIGH and that will keep you happy.

Why did you upgrade to 2x 980?

one of the 970 died and I was planning to do a new build anyway. otherwise my plan was to keep things this way for another year may be until next generation of cards come out.

Interesting. Because this gigabyte g1 gaming card is actually fast, another one would be 280... it has the same architecture as the 980. Now you have got me thinking. The bottleneck is the memory. But you say it's down to AA and 4k looks amazing in anyway without AA?

6gb is a bottleneck too, not at the minute but it will be.

So what games did you play in 4k with your 970gtx sli setup and what sort of fps did you get?

first thing don't sink yourself in this vram issue. at the moment it is more theory than actual world results. I played all the power thirsty games on 4K on gtx 970 sli (almost everything on ultra with AA off). Witcher 3 was just over 40fps with AA and hairworks off. Crysis 3 was pretty much the same. Farcry 4 stayed between 50-60fps. Tombraider around 60fps. All these are playable frame rates and no single card will do better than this. I overclocked my cards and I am confident that no single card beats a 970 sli setup at any possible resolution. You will want to buy a 980 ti or titan x at the moment only if you want to pick up another one down the line to sli. otherwise you will live with overall inferior performance to 970 sli. 970 sli is cheaper option for you because you already own one. but again that is assuming that games you play have good driver support for sli.

Thank you.

There is also the possibility that future games will also be programmed to take advantage of multiple GPUs(including memory) using Direct X 12.

Would a Corsair 850 WATT handle 2 of the cards?
