Ironically Nvidia actually acknowledged the shuttering problem (which affected minority of the users) and promised a release a fix...which they did
No they haven't

, Manuel promised a Whql driver when it's 100% fixed, if it was fixed there would have been a Whql release.
All they have released is beta after beta, followed by the 660 without a Whql driver.
This imo, ties in with the forum still not back up, already echoed earlier in the thread on numerous occasions.
If anyone thinks it's been 100% fixed then why haven't we seen a highly publicised PR statement from Nvidia?
Actually specifically for the poor crossfire performance/support, it was generally come from people that got crossfire setup...rest of the people that don't are simply quoting what they read from the end-users. And then we got some people insisting crossfire is fine, that if people that got problem it is caused by user error.
From my own experience and what I read around forums, I suspect that generally when upgrading graphic card, there wouldn't be much problem if the Nvidia driver wasn't fully removed, AMD on the other hand...using standard uninstall is not good enough, and with things leaving behind that could cause all kinds of problem when upgrading to a Nvidia, or even AMD card. And then the only solution is either get lucky with using driver sweeper, or doing a fresh install...
At work, test rig has both Nvidia and AMD drivers installed for testing gpu's, never had any problems.
Home rig has had both Nvidia and AMD drivers installed for Hybrid PhysX, for the last 3 years, never had any driver problems(that I can't blame myself for).
So yes, a lot of the time it can be user error/conflicts, it's not all down to AMD.
may be people should change the word "shuttering" to "crossfire" lol
When did you last have a CrossFire setup that you so often criticise?
You could go down and find out what SLi problems can be found in the Nvidia forums...
...oh, wait a minute isn't that the forum with zero cc details that still hasn't been 'fixed', considering all the 'hackers' stole was email credentials?
(this isn't a bash at SLi, it just gets sooo tiresome hearing about the downfalls/trashing of CrossFire from the usual suspects,
if it's worse than SLi, then it's not by very much-or no one would buy into the tech at all-period!)
