Affinity Patch

My new laptop has Windows Vista installed, which for various reasons I must
put up with.
Its a reasonably powerful dual-core machine with an NVidia graphics card, so
I expected
TORCS to run well.

When I ran the game though, I found that every 5 seconds or so there'd be a
hiccup in the
rendering of the game (which would freeze for half a second or so) and the
sound (half a
second of silence).  Its enough to make driving a car impossible.

Looking at the Task Manager I saw that TORCS was taking up 100% of _both_
CPUs.  
Having run into this problem in another game (Myth), I tried setting the
affinity on TORCS 
to just one processor.  All the jerkiness disappeared, with the graphics
rendering smoothly.
I've tested this on & off quite a few times now, and the affinity change
always fixes the problem
with no ill-effects at all.

Therefore I've made a change to windowsspec.cpp, which basically sets
affinity to a single
cpu on startup.

cheers
Andrew
