id has confirmed its new FPS will be optimised on the PS3 after recent frame rate comments

Numerous reports last week picked up on John Carmack's comments to Edge Magazine that Rage would run at 60 frames a second on the Xbox 360, compared to a paltry 20-30fps on the PlayStation 3. The programming guru's company, id, has moved to reassure gamers that the title will be streamlined on all formats.

"The Edge Magazine article has caused quite a ruckus," read the Rage Twitter feed. "We are committed to ensuring that gamers on all platforms have a great Rage experience."

It was reported that Cormack felt the PS3's rasteriser was slower than its 360 equivalent: "The rasteriser is just a little bit slower – no two ways about that. The RSX is slower than what we have in the 360. Processing wise, the main CPU is about the same, but the 360 makes it easier to split things off, and that’s where a lot of the work has been, splitting it all into jobs on the PS3.”

However, many commentators missed Cormack's later statement: “Everything is designed as a 60 hertz game. We expect this to be 60 hertz on every supported platform. The work remaining is getting it locked so there’s never a dropped frame or a tear, but we’re confident that we’re going to get that.”

Rage is being developed for the Xbox 360, PS3, PC and Mac.
