Good luck optimizing for shader code you have no access to, because that is (was?) the situation, at least for some previous games that used it. Not even the developers of the games have any access to it. Gameworks actually prevents AMDs to optimize paths in their drivers. Exclusivity does not matter a bit. Note that AMD also has a program that help developers write shaders and optimize their engines to work better on AMD cards. But that does not prevent NVIDIA to see the code and optimize their own drivers accordingly. So, to me the problem here seems NVIDIA's attitude to sabotage (for no technical reason, except economics, see the physX on x86 debacle when they refused to compile code for something else that i386) performance on other platforms for their own gain. Like physX, Gameworks is already showing itself for what it is and will eventually fail and be forgotten. And people will believe that AMD is at fault for the next NVIDIA "magic technology" that brought no gain whatsoever to the gaming world.
