Carmack: "Blu-Ray biedt voordeel voor RAGE en Doom 4"
Doom 4 is being set up so that it's almost certainly going to be cut up to three DVDs versus one Blu-ray. At least they've got the ability because of the way it's structured.""We would love to set the thing up where it filled one Blu-ray disc versus three DVDs, which is about the right mix, but the game just…we can't cut it into a third like that. We can cut it into two pieces. We've got two large wastelands on there. We just couldn't make an arbitrary cut.
Ondanks de moeite die er dus gestoken moet worden in de compressie van games op de Xbox 360 is het wel makkelijker volgens Carmack om te ontwikkelen voor Microsofts console dan voor de PS3. Al heeft dat er ook mee te maken dat Sonys consoles wat meer kracht heeft en je daardoor meer werk te doen hebt om er alles uit te persen.
"The 360 was easier to certainly to get to where we are now. More sweat equity had to be put into the PS3. There's a little bit more theoretical raw performance on the PS3, so we've got a little bit more headroom."
