Microsoft knocked their door and they're trying to understate the damage. This statement has been made just to control comments oh their forums

"You won't see different times of day per city because this involves recreating all the textures again (one for day and one for night). Whilst this wasn't a problem for our dev team, it was a problem fitting all this data onto a single DVD. So we've worked around the problem by providing different lighting models per city."

plain and simple.

isn't it?

OMG,

DVD9 is just 9 gigs, 15 might by your age!

I guess you had to much 4D gaming!

there's no damage, would you stop trying to see a problem where there isn't? They used a very common technique so they didn't have to make seperate textures for day and night, i'm sure when they saw all the fanboys saying this meant the game was being "limited" they wanted to react to that. It's not a limitation, they just slightly changed the way they made it.

No sorry Im younger lol

You fool!! Im not saying they are making the game go fourth dimensional, Im saying that 4d graphics are possible meaning that they look like there 4d not that they are man, and sorry 360 fans keep saying its 15 gigs it got stuck in my head.

Indeed, from a PR perspective, it was.

 According to them, yes it does. But that doesn't mean the level had to take 2 gigs, only that's how the developers made it. With any system, the dev's work with what they've got. The blu-ray disk takes a lot of space, so why not use a lot of space? Resistence Fall of Man took far more space than a DVD9 could take, but most of that seemed to be padding and waisted space. The dev's of Oblivian said that they found the PS3 disc reading rates slow, but compensated by doubling a lot of code, so they used one strength of the system to over come a weakness. That sounds like what the PGR 4 dev's are doing too.

This doesn't mean there's no reason for extra space, it just means that a game that takes up that space isn't necessarily impossible on a system with less space at all.

So you can increase the loading speed of a game by using the extra disc space? Does it work for ram? Sorry just curious.

 I barely know anything about tech, but I do remember an interview with the dev's in which they expressed some frustration towards the PS3 port. They said that to make up for the slow loading speed, they were doubling alot of code, so that certain rooms/textures/enemies (once again, I have no idea what) could be accessed from different parts on the disc. They said it wasn't very efficient, but it worked to speed things up a bit.

Yea you might be right about that.  I think half the problem is because this story had titles like "DVD size limits content...."  That's the name i saw here on vgcharts and on neogaf.  People never bother to even read the story most of the time.

They got a spanking from corporate and now have to clean up their mess.
