"almost complete" in implementation 2 years ago.
Gran Turismo 5 is "built to run at 60" frames per second, which makes 3D easier, as it's "quite difficult" for 30 fps to convert to 3D. Cause of delay?
"The 3D feature was almost complete two years ago, actually," Yamauchi-san told . "We could see that it was in that natural flow of technology and where things were heading."
"Discussions with Sony regarding 3D technology began more than three years ago. More recently we have spoken with Evolution Studios, who have put a lot of work into stereoscopic 3D, about things like video formats."
Evolution are developing the newly announced MotorStorm: Apocalypse for PlayStation 3, which has you riding through a disaster stricken city full of crumbling buildings and warring factions as you race.
"Because Gran Turismo 5 is built to run at 60 frames per second," he added, "it was easy for us to implement 3D. It's quite difficult to convert a game that runs at 30 frames per second to 3D.” Frame rate has been the problem for many titles going 3D.
It was reported that both 3D and PlayStation Move's inclusion was behind the delays to Gran Turismo 5, but Sony cite it as Polyphony's 'perfectionism'. GT5 was supposed to launch in March 2010 for Japanese markets but it missed the window.
Gran Turismo 5 releases exclusively on PS3 November 2nd in the US.
