So does anybody have this confirmed as working with CS5 and a FirePro card?
I could have sworn somebody Adobe had gone on the record that CS5 would support 10-bit color, but the comment quoted above is from May 19, which is fairly recent.
It works - sort of. The image display is good, super smooth gradients, but there are come glitches - the clone tool renders a little block in 8 bit aroudn where you're working, for example. And Windows Aero (if you're on Windows) switches into basic, non transparent mode for some reason.
So yes, it works, but it's not without irritations or flaws.
It's all in the article linked above. (http://www.imagescience.com.au/kb/questions/152/10+Bit+Output+Support
