The Xbox 360 and PC versions of id's Rage sport higher framerates than the PlayStation 3 version, the latest issue of Edge magazine reveals.

In a ten-page reveal in its latest issue, Edge writes that the Xbox 360 version of Rage - which uses id's new Tech 5 engine - matches the 60fps framerate of the PC version, while PS3 runs at just "20-30fps".

It's not mentioned whether the PS3 framerate will be addressed by the game's eventual release.

"The PS3 lags a little bit behind in terms of getting the performance out of it," John Carmack told Edge. "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," he said.

The PS3 edition was thought to be the most technically capable of the console pair, thanks to id being able to squeeze the gigantic shooter onto a single-player Blu-ray disc, compared to Xbox 360's four DVDs.

The developer also confirmed that a Mac version of Rage is still in development.

ooo la la.

Before you flame the developper remember...John Carmack is smart people. Very smart... Smarter than you.

Oh my 4 dvd's, no problem. This game is looking out to be good.

Maybe Carmack is just too proud to bring in the Sony Kung Fu cell coders to overcome the worse GPU.

Probably his mega textures just can't be helped by the cell

John Carmack = lazy developer confirmed?

A four disc fps. That is going to get repetitive

Interesting. Particularly as initially id made a lot of noise about Tech 5 was designed to be equivalent across all platforms - now, it seems it's design is better suited to PC/360 after all.

This may not be a surprise, given id's PC background, but I'm more than a little surprised that Carmack, who I've always held in high esteem as a coder and engine developer, seems unable to match developers like IW, whose engine runs 60fps on both 360 and PS3 and looks pretty much the same on both too.

I was hoping Tech 5 really would be the first heavy duty engine from one of the former big PC developers to run well across both platforms, but with Unreal tech now performing well on PS3 and with a new Crytek engine on the way for HD consoles it looks like id might have failed to equal the competition in the engine stakes.

Nice for 360 owners I guess. If this holds true at launch then its PC for me.

EDIT: where did the 4 disk thing come from?  I thought it was 2 DVDs - maybe 3 at the outside?

4 discs?

For a FPS game?

I have a feling this game will be huge.

Not surprised, 360 was always more future proof than the PS3 for true next-gen engines.

Game Informer said 2 disks for the 360, with the game world having 2 distinct sections.
