I see the desperation continues, if a graphics API could double the performance of any GPU, that would be front page news on every single Tech website, it would be a revelation of epic proportions.

When a guys doing a video blog from what looks like his bedroom. Its bullshit.

seeing that mantle is twice as good as older DX versions, whats the problem here, it would make DX on par with mantle.... problem?

Show me 1 link where mantle is 100% improvement on DX11, highest ive seen is 40% and this is at peak not an average, and guess what this news was a revelation and on the front of every tech website, it wasnt revealed by a dude on a webcam in his parents back room. 

Mantle performance increase was also because it allows PCs to have close to the metal performance that consoles have always enjoyed. Mantle will not give any performance increase to consoles. 

Dont get me wrong of course DX12 will improve xb1 performance, it will have multiple graphical API updates througout its lifetime that will be better optimised use new techniques and slowly increase its performance, but this will be the same for all graphics hardware for all platforms.
