A single core is never ever ever dedicated to anything on Windows, sorry.

The advantages in Windows of having multi-core improved over time. Multi-threading is needed for that. For the OS itself to take well advantage of multi-cores vs performance in a single core environment must include multi-processing abilities for core processes.

A related quote from a few years ago:

"Finally, keep in mind that the Windows XP driver model for Direct3D is quite inefficient, to such an extent that in many applications, the OS and driver overhead associated with issuing Direct3D calls approaches 50% of available CPU cycles.Hiding this overhead will be one of the major immediate uses of multi-core."

This may also help with regard to what I am pointing at:

Why's my single core processor faster than my dual core?
