Kazunori Yamauchi, the mastermind behind Polyphony Digital's Gran Turismo series, has insisted that the addition of 3D technology is not the reason behind the game's protracted development.
In fact, the legendary petrol head has claimed that 3D was up and running in the game as early as two years ago.
We could see that it was in that natural flow of technology and where things were heading,” he told the PlayStation blog.
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.
Because Gran Turismo 5 is built to run at 60 frames per second 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.”
