David Blythe, in his presentation at July's DirectX Meltdown 2005 conference (www.microsoft.com/directx), flatly stated that "games are CPU-limited". I'm moderate and co-own the X-Plane Development mailing list (see www.x-plane.com for the software). I know Austin (the guy who writes X-Plane) for almost a decade now. He on numerous occassions stated in technical discussions we had that CPU is the major limiting factor. In fact, in recent releases he switched to a multi-thread model in the core simulator engine to address this and support platforms that have the CPU capacity for it. >> What did you not understand Sasha?

Please show me a -single- game on the Windows market today that does not use DirectX. And the processing model used by DirectX is not unique to Windows. On all other platforms too there are things that a game does not have the time to wait on. Like making calls to play sound. Reading textures into the game cache. Making a network call during multiplay. These are all async calls. Which means the calls are serviced by system/kernel based processes. At the same time as the game continues running. > if cpu requirements go up, that does not mean that extra capacity, as you put > it will help. More bs.
