Just when we thought this roller coaster ride was about to come to an end, we find there’s one more scary drop: Sony is reportedly telling everyone interviewing Kazunori Yamauchi “to not mention Gran Turismo 5“.  So…what does this mean?  Obviously, it’s not good – presuming that Gran Turismo 5 is announced at Sony’s big press conference tomorrow, why couldn’t he talk about it?  It may, ultimately, come down to Sony not wanting any GT5 announcements to dwarf GT Mobile and the new PSP Go hardware, in which case, we may be waiting several more months for news about the big game.

It’s been quite a roller coaster as we wait for confirmation regarding Gran Turismo 5‘s appearance at next week’s E3 2009.  Things started out good, when our own Amar212 shared some cryptically optimistic information regarding an E3 announcement, but hopes were dashed when Sony’s biggest franchise was missing from their lineup for the show.  Today, we’re back up again, with encouraging words from an apparently reputable French PlayStation magazine, PSM3.

A rumored list Sony’s list of games to be presented at E3 2009 has popped up, and it has a lot of people talking – not for the games that are on the list, but for the game that is not: Gran Turismo 5.  We have anxiously been waiting for what Sony has called one of their “biggest events in the past 11 years“, and many legitimiate sources have hinted that GT5 and Gran Turismo Mobile for the PSP would both be making an appearance at the show.  Of course, it makes sense, given the fact that it has been so long since we’ve heard any news about the development from Kazunori Yamauchi, and the next big game show (Tokyo Game Show) doesn’t hit until September.

The engineers at Digital Foundry have used GT5 Prologue to demonstrate one of their new video performance analysis tools.  As you can see in the clip above, their software graphs the frame rate at a given point in time while marking each torn frame.  They cite all of the criticism that the game has received for “tearing”, yet their objective results show the game performs exceptionally well.  Another revelation: frame rate is cut down to 30 FPS during the “pre-race drive-by”, with lots of torn frames.  Once the player gets control of the car, the game rockets up to 60 FPS, with no obvious explanation.  Watch how the FPS is, otherwise, only really affected when  other cars are in very close proximity.
