Al menos deberias aceptar tu fanboyismo como otro ya lo hizo, antes de querer defender que los illuminati existen.

The answer is very different, a quick example would be TressFX AMD's physics rendering technology for hair, when the technology was first launched with Tomb Raider AMD hardware enjoyed a performance advantage over equivalent Nvidia hardware well into the double digit percentages.
But not long after launch Nvidia managed to close the performance gap to the point where now both companies are roughly on equal footing, that's because AMD's libraries were open to Nvidia to analyze and improve performance, similarly Mantle is open for Nvidia to implement its own libraries in as it sees fit.
Had AMD closed the libraries for its own technologies in Tomb Raider like TressFX, Ambient Occlusion (HDAO) and so on Nvidia users would've still struggled with performance issues today.
