Lets throw an article bashing amd all over calling the 2nd 7970 as useless as a single 7970...

All alone 64hz bug all over again....

XD


Not only is getting the same readings on the capture card thru fcats using vsync as fraps graphs, he also proves that a 2nd 7970 is no placebo..

Even that i would even comment on the 20fps issue he was having at just looking at the animations..
Is impossible to not even noticing that...

lol, really got to you hasn't it?

Everybody already knew that locking frame rate to refresh rate would sort the frame time issues.

The articles are more about how when GCN is left to it's own devices, Crossfire scaling is borked beyond belief. There is no 1:1 scaling, not even close.

Honestly, I know people round here wear their heart on their sleeve and invest a lot of time and effort into their builds but you maybe need to gain a little perspective so that you're not so easily wound up wink.gif

start with the summary:

Quote:
Until recently, very few people would have believed that AMD’s CrossFire and Eyefinity technologies would have had so many problems, thanks in many ways to previous testing platforms. As it stands now half of our six tested gaming titles show significant problems with single monitor CrossFire scaling and all six of them have serious problems with Eyefinity scaling. And that includes AMD sponsored titles like Crysis 3, Far Cry 3 and Sleeping Dogs.

NVIDIA’s frame metering technology, which still largely remains a mystery thanks to the company’s desire to keep its multi-GPU advantage as long as possible, is more important than we ever thought it would be and makes the GTX 680 stand out as a better solution for high end gaming than the HD 7970. That would not have been the case when looking at only single GPU results or by simply relying on the average frame rates of FRAPS data.

Another problem this causes for AMD and its partners is with dual-GPU hardware, the Powercolor Devil 13 or the ASUS ARES II. While both are powerful graphics cards, they depend completely on CrossFire technology to meet the performance expectations set by marketing and by cost and a quick glance at the HD 7970 CrossFire results I’ve showed you today (which basically mirror an ARES II) tells you that neither option is worth the price of admission.

It should come as no surprise that AMD was only recently made aware of these performance issues and was kind of stunned to find out how bad they were. The truth is that AMD could “hack” together a fix to make our frame time graphs look better but it would likely be a solution that introduced more problems than answers without doing the research required to get it right. The driver team has told me several times over the past two weeks that they should have a testable driver to fix the CrossFire problems “in 2 to 3 months.” Until then, buyers that consider a multi-GPU solution a goal or a requirement will want to seriously debate dropping Radeon cards from consideration.

Whoever who thinks thats going to get twice the performance with a 2nd card i mean i just loled..

Now if you look at this one here


then compare it with this one

just a lil bit closer for that to happen on both sides XD

i would hush when im around if i were you seriously

You know what? Lets wait to july maybe that dream come true..

Wait what the ****? Crossfire FPS is lower than with a single card? Come on, i know crossfire has issue but what the hell is that?

welcome to a "new" way of benchmarking.

Wait what? all this frame latency issues on dual gpus on amd were debunked by the same guy using vsync...
His method of capturing frametimes is as good as using fraps... lol

Those numbers look quite well for the 680 SLI. What's your point?
