This is from the same website that showed micro stuttering on 3870X2 and 9800GX2. Looks like it's still present on 4870X2 as well.

Well that sucks.
Definitely knocks the 4870 X2 down a few pegs for me...

That's just one review, though. Let's wait for others to roll in, particularly from bigger name sites.
Thank god i didnt hold back the 280's purchase.

This is PC Games Hardware, they suck just like all the other german magazines.

At least they investigated the micro-stuttering issue , unlike many other review sites that keep ignoring it.

This review was done at the same time like the other previews with the same engineering sample, not final bios and ready drivers. Originally the review was in German couple days later it was English translated and it looks like they are trying to get some extra hits publishing the story for the third time. I wonder if they ever get preview sample again.
I watched the video and most off the run was around 10 - 15 frames, with frames like that a single GPU will also show stuttering.
I mean first they say the crossfire was not working and than they show a microstuttering video.

They just do it to get some attention. I mean that Crysis test is pretty ridiculous. A game with problematic multi-GPU scaling, especially CF, and an AVG framerate of 11-15 FPS. It's not playable anyway! And mirco-stuttering is not noticeable at higher/playable framerates.
I'm not sure if articles like that even help fixing that problem, PCGH doesn't have as much influence as other sites like [H] or Anand. Like Heinz68 said, this is the second or third time they've published an article about this with the 4870X2, they're just trying to get some attention. Not for us gamers in order to fix that problem, just for their site. PCGH was a german-only site a few months ago, they are now trying to get more readers with pathetic methods like this or posting their own articles as news on VR-Zone. As I said before, they suck ;)

At 11 fps ? The game is totally unplayable at that speed, with or without micro stuttering.
I think that Crysis needs a gfx subsystem with 9 GFlops & 1 TB/s.

I was sorta hoping that this card would provided better "quality game preformance" than my 9800GX2.
actually, how does it fair compaired to the GX2
FWIW, I do get a micro-stutter when GPUZ sensors is open while gaming on the 4850. It took me a while to figure it out because I was investigating temps and 3d clocks at the time.

can't use rivatuner?

Still not supported. My biggest complaints about the 4800s are lack of support. I know it's a matter of time, but I'm impatient.
Ati Tray Tools doesn't fully support it.
Rivatuner doesn't.
The drivers are still needing a lot of work too.

i'm sure Unwinder is working on it.
I was just saying that for the years i used Rivatuner it never caused stutters when running in the background.
As the GPUZ sensor tab refreshes, it 'ticks' and that is the exact point of my stutters when using it. That may be why it has the check box to enable/disable refreshing while in the background.

They need a definitive way to define it with emperical data, going off someones ability to detect it isn't consistent. I like the way 101 approached it in this thread:

I'd like to see a data intesive comparison of single card vs. sli on various games with various sli cards and with different cpus...

Guru3D also mentioned some stuttering in GRID in their preview.

There's no stuttering or lag in Crossfire until you hit the VRAM limit. Otherwise, it's smooth as silk. I've tested over 12 games with it and haven't noticed any of them lagging one bit. Performance is every bit as clean as it is on a single card.
Much ado about nothing if you ask me.

Tis true. Me too. Also caused stutters in Furmark for me when I had GPUz running. It seems to interrupt ATI's driver when it is in the background.

That explains the GPUz thing. Thanks!
Comming from a year of heavy duty eVGA 8800GT Superclocked play time, I have to say that the drivers for this 4870 have been fine for me in the dozen or so games I have played on it. Only thing I find missing from the ATI drivers is in Vista and vSync forcing.
Thank goodness someone here told me about D3DOverrider because I was getting pissed off. I mean 9 out of 10 games has vSync in game settings. But for those that don't I was getting pretty hot under the collar about it. I HATE tearing.
Now I run around in COJ maxed out in all it's glory and my framerates are smooth like silk. 50 - 60 fps at all times and no tearing. TY D3DOverrider!
If all I have to do is run D3DOverrider to get vSync with tripple buffering, you would think they could enable it in driver would they not? Common ATI! Get er done!
Outside of that, my experience has been a good one.

Oh and as for the stupid review by that site?
Nice smear campaign. :thumbdwn: FAIL.

There is a long thread at ExtremeSystem Forum (http://www.xtremesystems.org/forums/showthread.php?t=194808&page=13) about microstuttering.
User with the nick 'bedlamite' received the HD 4870x2 and promised to post some testings. Anyway only few days before we see official reviews.
For the time being his first impression:
Post # 304
So 4870x2 came to me.
What can I say.
I think you'll be satisfied with this card
MS is not completly fixed, but there is big improvement. So big that most of ppl won't ever notice that smth is wrong.
Post # 306
It's not much worse than single card. You can see some pattern, but it has minor influence for your gaming experiance (in 99% of cases).
Problem is with some strange spikes, which i've noticed, but unfortunately I didn't have enough time to check it better.
