The Fiji series is shocking with Mantle in BF4 and I don't believe AMD are revisiting it either. I was a little disappointed to find that out and a 290x was as quick as a Fury X when both are running Mantle.
I would have liked to have tried Freesync and if Greenland is faster than Pascal, I will be trying it.
Yeah, it is a shame. But some reading around and some tweets from Johan Anderson may have pointed the culprit to being WDDM 1.1-1.3 getting in the way. They essentially had to write hacks around it for memory management on each GCN architecture. So it could be the reason why the problem occurred with the 285 as well. since they had not written the workarounds for it. And why BF4 has such bad memory management for Mantle.
He also went on to state that WDDM2.0 has none of those problems since it was made for DX12. And Mantle could see a performance improvement due to them not having to hack around the memory management. But they have to write the support for a WDDM2.0 pathway for the best effects.
But that also then restricts Low Abstraction API's to Win 10 for the best possible performance.
