Doom 3 is does NOT support SMP, Carmack prefers the elegant approach to single cpu's.
We haven't gone through all that decision-making yet. But I think for our next project, we'll probably take a PC-centric approach, given what John Carmack said at his programming keynote at the Game Developers Conference this past spring. He said he didn't really like the technical aspects of the [next] generation of consoles--in terms of Xbox 2 and PlayStation 3--with their multithread approach, dual GPUs, and dual processors. They don't have the simple, elegant approach of a single CPU and a single GPU. Given that's where John thinks you can do the most exciting things from a technology standpoint, I expect that's where he's going to go from a programming standpoint.
I've read through this about three or four times and it sounds like the guy who wrote the article doesn't know either, because of the way he seems to be paraphrasing most of Carmack's keynote.
Using phrases such as "I expect..." means that the guy who wrote this article is speculating doesn't know for sure either.
Does anyone have a definite answer here and not just speculation and conjecture?
