360/PS3 Comparisons

[Kaden]

Porting isn't really the problem anymore, like Waff said. The problem with multiplatform releases, right now, is that they're being written on the less powerful console and just dropped into the PS3. Of course you're not going to get the most out of the PS3 that way, and writing games the other way around just isn't practical at this point in time.

They've been developing the technology to allow games to up-spec when they have access to a multi-core processor. That's been worked on for a bit now. So you'll have games running smoother once they're better able to use all the extra cores in the Cell processor. Admittedly, the last time I read anything about that was last year.

My guess is that, eventually, multiplatform games will run smoother on the PS3 than the 360 (there's no way they'll just stop using the DX toolsets in favor of Sony's), but that "eventually" may or may not fall within the lifespan of this console generation. Until then, sadly, you're basically paying for hardware that's not really being used.

EDIT: Right, obviously none of that really applies to exclusives.
