I thought some of the next-gen games are going to be quad threaded and utilize all four cores to a certain extent?
Well, first let me say, that I know very little on the subject, so don't necessarily believe what I say!
I was being tentative because, while I know little about multi-threaded coding, I do know that it is a very involved affair, an not something that game designers can trivially just do at the press of a button. So recoding a current game or engine for multithreading is a big no. Now, given the last 5-10 years, companies have been reusing code and game engines (which, given the complexity of games these days, is really the only economically viable choice), it is no mean task to suddenly come out with games optimised for quad-threading.
All the same, the basic concept of multi-cored processors is such a good one, I can't see the computer industry not making the best use of them in the future.
