How many DVDs does it take to screw in a light bulb? ... Are we talkin' a Mega Texture light bulb that casts penumbra shadowing?

In an update to id Software's data dilemma, John Carmack tells Tom's Games, "We're pretty much resigned to the fact that we're going to make [Rage] fit onto two DVDs on the 360." In other words, Microsoft isn't about to write off the steep royalties that allegedly add up with each additional game disc. The good news is you'll only have to whine for mom to swap your Xbox 360 discs once. The bad news, as headlined last week, is that Rage for Xbox 360 will supposedly look worse than the PlayStation 3's Blu-ray version due to data compression. But how much worse?

"All of the key scenes, the things anyone is going to take a screenshot of are going to look exactly the same on both platforms," Carmack explains. "They'll get the high quality compression. But if you go into some areas in the wasteland, like behind a fence where nobody will typically go and explore, this is where the 360 version may look a little blurry compared to the PS3." We hear id's been sweeping some artifacts under the rug too. And watch out for those jaggies hiding beneath the bed!
