Normally, rendering threads that really do graphical output are never
split across CPU's, even on big machines. This, because there usually
is 1 graphics pipe (at least on consumer hw) in which to pump all
vertices and information.
Threads come in handy to splice up pre-graphics calculations. GPL is
FULL of that, so splitting the AI and user physics into 1 thread, and
the drawing into another would work. Although ofcourse the drawing
thread should begin drawing ASAP. It's all a matter of balancing out
the workload.

MS SQL Server has options that eventually boil down to processor
affinity calls.  The goal there being to increase performance by
decreasing the number of processor cache reloads.  It also can be
used to prevent an application from soaking up all available
processor time although I think MS has kicked that up a
notch in Windows 2000 with processor quotas (at least they
said they would, don't know if they actually did).

Sadly, I don't see SMP boxes becoming more popular.  They
are always last on the list of setups to support and test for
which doesn't exactly endear them to mainstream users.
Anyone recall the lovely original SB Live! drivers?
