None, or am I missing something, cause i have seen no mention of Vista
being optimized for DualCore, as they mention thing like prefetching.
Also Ballmer said Vienna is gonna take advantage, no metion about Vista
here too.
Is it any better than Xp at this?

Windows XP Professional takes full advantage of up to 2 physical
processors (and will also use hyper threading and dual cores too.
Windows Vista will take full advantage of a dual core and dual
processors systems so effectively running across 4 cores on a system
with 2 socketed dual core processors.

It definitely sounds like you are missing something.
The professional Windows NT based system (Windows NT Workstation,
Windows 2000 Professional, Windows XP Professional and the top end
Vista versions) have always been multiprocessor capable and will take
advantage of them. The issue with many of the desktop operating
systems and multi core/processor support has been the lack of
applications written to really take advantage of multiple parallel
execution processors. Obviously just running a couple of different
apps you will still see the benefit of multiple processors and cores.
 
Check the Performance tab in Task Manager on a dual core system and you can
see for yourself. Two cpus.

You are right.

I know I said that
"...
...."

If you always use only one application at a time and if this
application has only one thread,
then, there is always one core that is not used by your application.

I suppose that games use many threads.
We can see how many threads used by an application with Windows Task
Manager.

Have a nice day!

Indeed but then your application can monopolise one core and leave the other
free for OS tasks, and you still see a win.
