This has always been the point of NVIDIA's propertary game engine technology for more than a decade now - give it away for free or very often for big titles integrate it into game engines using NVIDIA developers (who often come to work on site.) Then once the game is released mention that it works better/looks better on NVIDIA technology than on competitors (AMD/Intel) GPU technology. And of course blame it not working well on AMD/Intel on their "inferior" technology.
NVIDIA must be loving this controversy as it was the whole game plan all along.
