Frame Rating and AMD crossfire issue

Some of you might know the site www.pcper.com. In case you do not know it check it out. They so great Hardware rewievs and stuff.
So back to the topic:

AMD Crossfire is a lying at frame rates.

Simple as that. Dont believe me ? Check this rewiev. Please read it seriously because it is quite complicated.



Just wanted to know what you guys think and maybe we can get Tom to make a vid about that, because i think it is a pretty big issue.

Here is just an idea on what the whole issue is about:


Everyone until now has seen that as the results. We see that a 7970 GHz Edition is little better that the 680. Also if we do the crossfire and sli comparisons.
BUT now look at this graph:


That the the result of the exact same test just somehow different. Take a look at the 7970 crossfire result. Almost the same as a single 7970.
So what observed means is ... this is taking too long to explain just watch the video Everything is explained there.

If anyone didn't notice then surely they are brain dead. I way playing Far Cry 3 with 2 7870's and the thing was just a cluster #&%@ of micro stutters Fraps would present 30 FPS but when you are actually looking at it it's actually half of that :\

Dual cards suck arse period there is a reason why gen after gen people just buy a new single card.

So, we have to trust a guy, with a home made overlay, some dodgy second system that records video from, supposedly, the same source, and after all that, we have to trust that all that info and data is processed without any bias by an nVidia made tool?

None of them mention that it's a stupid investment on either side.

I am using two 7970's and up until the 13 series drivers, micro stutter was horrible in crossfire.
But now the issue of micro stutter was pointed out to Amd they've seemed to have got there act together and my gaming experience is buttery smooth on 3 screens at 5760*1200 .
I was tempted to switch to Nvidia because of this but now there is no reason too and I have found no erratic drops in frame rates.

@Deceit It is not about frame drops. It is about driver sending out a frame that is 5 pixels small. Fraps counts that as a frame but you dont see it as a real frame on the monitor, because it is only a few pixels high. So fraps is reporting a "faked" number of fps.

If I had a pound for every time some one said AMD have got their act together with drivers I would be a rich man.

I don't agree with that. I will make some videos of me playing all of my games perfectly smoothly on my rig. I've had Crossfire a couple of times and both times it was absolutely crap. Every time I've ran SLI I've had minimal issues that are taken care of pronto.

Edit in fact I don't need to. Watch the video.
