Gran Turismo 5: 'It's still work in progress'

Kazunori Yamauchi talks GT5 performance and developing GT6

If any other game had been in development as long as Gran Turismo 5 and suffered as many delays we'd be very worried.

Kazunori Yamauchi assured eager driving fans - many of which had already been pushed to breaking point by numerous prior delays - that GT5 wouldn't suffer any more delays.

It stung a little bit extra then when Sony eventually revealed that GT5 would once again be delayed in the U.S. and Europe.

However, we can't help but feel that the delays might be a measure of Polyphony Digital's enthusiasm and dedication to create the perfect racing simulation experience.

We sat down with Kazunori Yamauchi for a quick chat about the performance of GT5, potential content additions and even a little Gran Turismo 6.

Is there any possibility of seeing motorbikes in GT5, or a new Tourist Trophy?

The environment we have right now allows us to drive motorcycles, but we need to get Gran Turismo 5 done first. Once that's out of the way, if there's a strong demand for bikes that's something we'd consider.

The ready races seem to be limited to two cars. How many will the final version support?

In the Dirt Trial racing, we think that two cars is plenty, because the car in front kicks up a lot of dust that goes right into the camera and makes it difficult to drive.

But selecting the Dirt Track on the online mode, you can drive with many more cars that way.

And the Rally mode is different again; each car is on a time trial, staggered by 10 seconds.

Have you started work on GT6?

There were a lot of things we couldn't include in 5 that will carry over into 6, so in that respect, development has already started.

Will the engine sounds be improved over time?

There have been a lot of improvements made to the engine sounds. Obviously it's not enough, there's more we can do to improve them, so it's still work in progress.

Will the game run at a rock-steady 60fps?

This is a major issue for us in GT5. Our engineers complain every day: 'Isn't it enough that it's in 1080p? Does it have to be 60fps too?'

But I think 60fps is very important, so we're working towards perfecting that.

There might be times when you have a certain combination of conditions that come together, especially with the weather effects; the game might briefly drop from 60fps, and for that I beg your forgiveness!

If you're going from a standing start at number 16 and all 15 cars in front of you are kicking up water, there might not be 60fps at that moment.
