The application is surprisingly simple. Each PS3 is dedicated to rendering one part of the enhanced 2160p image, with each PS3 rendering one full 1080p image. When combined, all four images turn into something that would make videophiles cry.
That wasn't the only fun and games at the event. No, Polyphony also ran another experiment with 4 PS3s: they were also able to create a 240 fps experience. Each PS3 would render alternating 60 frames per second, so that the end result would be blisteringly fast. At that point, we doubt the human eye would be able to appreciate such fluidity.
So, guys -- how 'bout you stop partying and making amazing 2160p tech demos, and uh -- you finish Gran Turismo 5? Please?
