The original Gran Turismo was a marvel piece of gaming technology back when it launched on the PSOne. With remarkable graphics for the time, the series has since evolved into something much more. While talking with Venture Beat, Kazunori Yamauchi discussed many aspects of the title, but the most impressive definitely comes from the amount of polygons the game is currently moving at. Back when Gran Turismo first launched, the title had cars detailed with 300 polygons. With Gran Turismo 5, they were able to utilize 500,000 polygons in each car.
Kazunori Yamauchi: “We had maybe 300 polygons in a car in the first game. Now we have about 500,000 polygons in each car. Back then, pieces of the car were more like symbols. Now they are real and reflect light.”
The exact number of polygons used in Microsoft's Forza 3 isn't known. We have tons of GT5 screens for you to bask at below in the slideshow. Sony has just released completely new screens which you can find here.
That's quite the difference from the first game lol
