Ya... I was expecting to hear headlines saying Mantle blur has been fixed AMD owners rejoice.. It was proven that DX 11 IN BF4 was sharper in comparison to Mantle when it first came out. I was like meh... I'll get the game when that bug is fixed. Then I found out the 7970 is not fully optimized for Mantle yet .. anyways thanks for letting me know none of this has happened yet. And I'm sure AMD would have hyped it up like some of you claim they would... not quietly release a mantle improvement. When I first bought my 7970 it took a several months for it to become compatible with Windows XP. But to my surprise this is a longer wait (and dont complain i use Windows XP/7) I know mantle doesn't work in XP.
