GRAN TURISMO SERIE TABASSAGE
Take, for example, the standard bearers in graphical realism on console, the literally incomparable Polyphony Digital. E3 played host to a couple of videos from the developer designed to showcase Gran Turismo on PS3 and PSP. The thing is, neither of them was really a true indication of the quality of graphics you'll be seeing on your console. You can argue that they were effectively "mood" pieces, designed to make an impact at a big industry event, but awesome artistic merits aside, the trailers and some of the associated shots were still some way removed from the actual game they are designed to showcase.
Polyphony Digital typically embellish the base gameplay visuals with additional graphical bling for their replay modes (hence the drop from 60FPS to 30FPS in GT5 Prologue), and it's from here that the raw assets are usually derived for their trailer work.
However, what we are seeing in Polyphony's trailers are intricately directed and rendered images where the samples used to create the motion blur are massively increased compared to in-game video, giving an ultra-realistic feeling of movement you won't see in the game. Any visual deficiencies that may be seen in actual gameplay (such as "jumps" in LODs as objects move closer to the viewer) are effortlessly removed. By rendering the video internally at an impossibly high resolution, the maximum LOD models are automatically invoked, high frequency shimmering on texture detail is smoothed away and of course, and any artifacts linked to alpha textures, specular shine and of course "teh jaggies" are disposed of as a matter of course.
The video is "in-game" to the extent that the tracks and car models are likely identical to what is used in the final product, but the increase in graphical fidelity combined with the beautiful camerawork results in a look that is some way beyond what the final product is capable of, short of Polyphony coming up with a technological quantum leap that dwarfs its existing work in GT5 Prologue. In this case, the result is to make an already staggeringly realistic game look right up there with some of the best that CG has to offer.
The marketing for Gran Turismo PSP seems to have been a bit of a puzzler for Sony. On the one hand, hands-on gameplay reveals a technological marvel that is pushing the handheld platform in ways that has never been seen before. On the other hand, it is bound by the physical limitations of the PSP's 480x272 screen and its fairly limited graphical capabilities. It looks awesome on the PSP's 4.3" screen, but patently not so attractive on a high-resolution monitor in the middle of the most important Sony presentation of the year.
The trailer above appears to hints at GT5-levels of graphical goodness, downscaled and super-imposed onto a rendered PSP screen. What was all the more telling was the fact that at E3, this trailer was followed by a very authentic-looking PSP video for Metal Gear Solid: Peace Walker, which aside from scripted camera angles and action, was clearly running on the actual game engine. For comparison purposes, a handful of genuine GT PSP shots have been released, which are somewhat different from some of the others which some say are derived from the PSP version's Photo Mode.
