Well, who do I believe.. my own experience as a developer of over 20
years.. industry experts such as David Blythe, Microsoft's software
architect for Windows Graphics & Gaming Technologies... or you and
your friend's limited experience on an old system?
David Blythe, in his presentation at July's DirectX Meltdown 2005
conference (www.microsoft.com/directx), flatly stated that "games are
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.

Bs! 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

More bs. Or are you telling me that my 12 node Linux/Sun cluster is
not about CPU capacity meeting increase CPU requirements?

You are confusing ASIC's with multi-threading (a software model) with
the dual CPU capabilities.

Please tell that to the developers of today's game and that they have
it all wrong.

Ignorant then? Or simply having an opinion on everything?

When it looks like bs and smells like bs.. I call it bs. But then
that is just me...
