A
The undocumented (and unsupported) AutoCAD command DUMPMEMALLOC offers among other the option Affinity which enables the so called "affinity" - an association of a Windows process (ACAD.EXE in this case) with a specific processor (or CPU core) on multi-processor and multi-core (dual-core, quad-core) computers. After enabling this option, AutoCAD will run on a single (the first) CPU/core only.

A similar function can be set in the Windows Task manager.
