Nvidia likes to use Gameworks etc as a weapon against AMD. Like when they turned up tessellation to ridiculous levels because AMDs cards didn't have the hardware for it at the time.
Crysis 2 simulating an entire ocean to render a puddle comes to mind. Also tessalating perfectly leveled floors IIRC.
That has been throughly debunked a million times over. The ocean only renders in wireframe mode because occlusion culling doesn't happen in wire frame mode.
