combjelly: Remember thst Abrash was hired by Microsoft to work on this project so he should know what XBox is going to do. You have to realize that Abrash was hired by Carmack to make the graphics for Quake to work (or at least he claimed this while writing his DDJ column on 3D graphics), and he went to Microsoft in 1997 to work on XBox That definitely adds some weight to his words! ;) Actually, I know who Abrash is, I just didn't know that he had written the article. If you look at it: ddj.com it is just signed "-- M.A.". The problem, I see now, is that I had actually not read the ARTICLE, only the separate "sub-article" on memory bandwidth ;). Still, regardless of Abrash's expertise, there is NO debating whether or not Quake3 saturates the 1GB/s memory bus of an Athlon system. That is fact, not speculation. I notice that he left id during Quake2 development. I may well be that Q2 does not strain the FSB to any noticeable degree. However, that is quite clearly not the case with newer 3D games. This was evident during the 100MHz to 133MHz memory transition and even more so now, during the transition to DDR SDRAM. That he completely ignores the industry's rush to increase memory bandwidth (even in non-UMA situations!) is also somewhat disappointing. Oh well, I guess I'll go read the FULL article this time ;). -fyo
