Are there details about this? I've read that nvidia drivers would actually patch game code by replacing functions at runtime.

Both ATI/AMD and nVidia use all kinds of tricks to outcompete each other since gamers only look at the fps count. That means driver optimization for specific games, even dropping fidelity a bit when that means more fps. Also, nVidia has teams that take over engine code to 'help' software devs making the most of their hardware which gives them an opportunity to push specific approaches that don't work as well on their competitors cards.

"Nvidia Gimpworks" - it isn't said in the video, but: while these techniques are slow on nVidia, they are even slower on AMD. Especially gratuitous tessellation. https://youtu.be/AUO3LEjWsw0
