What's the frame rate supposed to be?
A tenth of a second or more (Sleep is a minimum) seems like entirely
too long, especially in a low priority thread.
Sleep(0) should be adequate, but every frame might be better..

This is the part that could use multi processors if this were 3
threads instead of one.
Setup a minimum of 3 buffers.
(Approximate timeline)
			GrabBuffer( 1 )
			GrabBuffer( 2 )
Wait for GrabBuffer( 1 ) then	Process( 1 )
			GrabBuffer( 3 )
Wait for GrabBuffer( 2 ) then	Process( 2 )
Wait for Process( 1 ) then	Display( 1 )
Wait for Display( 1 ) then	GrabBuffer( 1 )

I think I'd use events for the WaitFor
And a Sleep(0) each iteration in all three threads.

GetProcessAffinityMask
	reduce the mask to a single "on" bit then
SetProcessAffinityMask
