Is there any plausible reason why double precision can only be used on highlevel (and often more expensive) cards?
Where does the restriction comes from? From the driver, the hardware or the ICD-model file?
Is there any hope for double precision support for a HD5670 card in the (near) future - perhaps the next release of ATI-StreamSDK?
Thanks for your explanations!!!
PS: I want to avoid to buy a new card like HD58xx - because i would need a new tower, fans and powersupply as well. That's too much for a short test on what i would gain for my scientific project.
