From the articles I have read I am under the impression that WSC is being
optimized for the P4 and not for Athlon. Is this correct ?

ANYTHING but full optimization for Athlon is complete short sightedness

Below is some info from Tom's Hardware on AMD and SSE(2).
18 of the 'Enhanced 3DNow!-instructions are identical to Intel's
SSE-stuff for a long time. Now AMD added the remaining 52 instructions
as well as the status bit that is probed by software that wants to
know if the system processor supports SSE. This means that Athlon 4
basically 'understands' all SSE-code and is therefore able to take
advantage of software that was SSE-optimized. The fact that AMD is
finally following Intel's lead can be seen as the first step towards
AMD's future 'Hammer'-line of processors, which are supposed to come
with a full 'SSE2'-implementation. Those are the 144 double precision
floating point SIMD instructions introduced by Intel's Pentium 4
processor last year.
You sure AMD is to blame?

AMD's pendant was first '3DNow!' of K6-2 and K6-3 and later the
'Enhanced 3DNow!' of Athlon. These AMD-specific SIMD-instructions
proved pretty much just as powerful as Intel's SSE, but AMD continued
to have a rather hard time to make software developers implement code
with those instructions. Due to Intel's influence in the business and
the big success of Pentium III, the implementation of SSE in current
software is much more common than 3DNow!-support.
There's also the fact that Nvidia uses now enhanced instruction from SSE2? for
there drivers starting with detonator 12.10 that really helps the P4.
The bottom line is, if a software is enhanced with SSE2, then the P4 takes the
lead. If the software is not, then it's AMD and which is the case now for the
vast majority of software present today.
I have chat with a lot's of people on the subject lately and some of them seems
to panic at the fact that WSC will have enhance SSE2 instruction built in,
thinking there AMD won't be able to run at all. This is simply not the case, WSC
will work well with P3 (733 Mhz and up is preferable) and better with AMD (sheer
speed of the processor) But will run even better with SSE2 enhanced CPU, which
is P4 right now, until AMD comes out with the Hammer CPU.
So there's no need to panic...
Btw I've read Tom's hardware tech stuff on the subject, and back in Nov 2000, I
did an interview with Chris on this (and DX8) and the article is right there :
http://www.simracingmag.com/wsc/articles/00q4/wsc_interview_1.shtml
So this is not "new news" at all

Oh, I'm not panicking at all. Just trying to alleviate the pain of
some that are. I have an Athlon 1.33c with a Geforce2 and I expect
that to run WSC quite well with maybe a few options tunred down/off.
By the time WSC gets here who know what machine I will have anyway
(maybe Hammer), I tend to upgrade fairly frequently.
Thx for the interesting read.

For MY machine - I wouldnt touch ANYTHING but Athlon
Intel systems are MORE EXPENSIVE and SLOWER
