Are ATI game optimizations the same thing as Nvidia's?

[Sean Cousins]

I saw a website that has ATI slamming Nvidia for their game
optimizations in the drivers. It showed a number of games that had
much lower frame rates when the optimizations are turned off because
the game optimizations turn down IQ. How does ATI game optimizations
work?

I don't really know, but I do know this ... the nVidia ops are for the
purpose of knobbing down the video settings because the nVidia
cards simply cannot run at the higher video settings without a lot
of artifacts and blue-screening.
