"The PS3 lags a little bit behind in terms of getting the performance out of it," Carmack explains. "The rasteriser is just a little bit slower - no two ways about that."

"The RSX is slower than what we have in the 360. The CPU is about the same, but the 360 makes it easier to split things off, and that's what a lot of the work has been, splitting it all into jobs on the PS3".</blockquote>

We recommend they speak to Naughty Dog immediately.
