Hardware Analysis have a new article out called Nvidia driver cheats? truth or fiction? Here's a snip.
I think the jury is still out on what is the proper way to render frames; both companies have a different approach to calculating textures, doing anti-aliasing and all the other 3D calculations. Thus it comes as no surprise that Nvidia indeed renders scenes differently than ATi does, but where do you draw the line between a cheat, an optimization, a shortcut or an architectural difference?
