So, I'm kinda hoping with the 7970 out, perhaps you guys might be willing to divulge the secret happy dance to making uav11 work? I thought perhaps it was that typeless read-only uav thing, and tried it because, well, bascially what I need is a nice big constant buffer. (ok, big is a relative term, but bigger than the constant buffer). I figured, well, a cached read-only uav should be about perfect, and I suspect it will work rather nicely on the 7970s since you said there is basically no more constant buffer.
So a follow up would be how would a typess read-only uav be implemented on Caymans? (wrt caching?) Speed is obviously "my thing" 
I have a perhaps nice time/space tradeoff, but if I can't get caching, since the time is already fairly low, it may not be worth it. If its cached, I suspect I'll see a decent improvement! If its only good for the 7970's, well, it may not do me much good yet...
