Which is a load of rubbish
http://www.nvidia.co.uk/content/PDF/kepler/NVIDIA-Kepler-GK110-Architecture-Whitepaper.pdf
http://docs.nvidia.com/gameworks/index.html
etc. etc. not to mention extensive sample and game development whitepapers, etc. nvidia do and if you license the gameworks libraries you get far more access to the source and documentation than is available publicly let alone if you make use of the nVidia's developer relations programs theres a whole extra level of support even to the point they will build development drivers for specific needs and rollout the features into the release drivers for a game release.
The first one is an overview.
I dont see the point to lie. Even timothy lottes says the same. Which he was an important ex- nvidia employ and now an epic one. We dont know why it going one behind the scenes so we can only speculate. Or put ltmatt to ask them
