I'm glad you got to the bottom of things. I guess that means that I the next card I add will be a 79xx card instead of another 69xx. I can't imagine why AMD thought worse accuracy was acceptable considering their whole push for compute oriented video cards and APUs. Then again, maybe that's why things were changed with the 7xxx cards (assuming you had no errors with those)?
It's actually not something you can blame AMD for (and they were quite helpful in diagnosing this issue). The function in question is documented to have implementation dependent accuracy. It was probably not a good idea for the author of the 3rd party FFT lib to make use of this function, but that's just my personal opinion. We will get rid of this part of code to make sure this doesn't hit us again with future cards.
* Known issue: no OpenCL support for Mac OS X for the time being (we're still looking into a potential Apple bug)
I could swear that I saw a message yesterday, talking about how this was fixed (hopefully). But I can't find it now, and I cannot get any tasks for my mac. Was I hallucinating?

Maybe you had sort of a vision, because I've just released, here on Albert, a version that indeed might work on Macs for AMD/OpenCL under OSX (Lion). :-)

When you're able to try it on both HD 69xx cards and similar HD 79xx cards, could you give us the relative speeds of the two?
Some of us would like that information before deciding which card to buy next.
