Windows should show *two* graphs if you have two CPUs (or two cores,
which is the same thing).
Are you only seeing one?

Only if you have "One Grap Per CPU" selected in task manager, otherwise it will show
one graph for all CPUs.

Well, if that's the case, I think the next step is quite obvious...

In my experience task-manager _can_ err in the other direction - e.g. a
single-core "hyperthreaded" shows up as two (virtual) cpu's so task-manager
reports 50% overall usage while in reality the usage is closer to 100%.
As for 3.6 versus 3.7, what are you rendering? Meshes? At this stage and
for my needs I get about twice the performance from multiple instances of
3.6 compared with running 3.7. Some results I got are here:

Indeed, it should be. I only mentioned it for bagger to check while he's in task
manager if he only
sees one graph.
Also, what if you aren't using the SMP "driver" in XP? I imagine that would also
cause only one
graph to be displayed.

IIRC, it should show 50% if only one of two cores is used - however, I'm
not running a dual core machine, so take my advice with a grain of salt.
Yes, every core has a separate FPU.

For what POV-Ray is doing, the choice is OS is (almost) irrelevant.
