ATI cards improve Dawn's image and performance
A group of MIT engineering students have written a piece of software (Open GL wrapper), that allows
users of certain ATI based cards (M10/R300/R350/RV350) the ability to watch Nvidia's superb Dawn demo. According to Rage3D, both image quality and performance are improved when viewed with ATI's Radeon 9700 or 9800 Pro cards (when compared to the competing Nvidia product).
For all ATI Fans who enjoy the dawn demo and would like to run it
