Multiprocessor plug-in

On multiprocessor systems, After Effects uses a multiprocessor plug-in to accelerate processor-intensive operations,
such as movement, rotation, motion blur, and blending. Performance improvement also depends on factors such as
the operating system and the type and number of processors.
The multiprocessor plug-in is installed automatically during After Effects installation.
The multiprocessor plug-in for Windows XP Professional (MThread.aex) works on multiprocessor systems,
including systems with virtual multiprocessors. The multiprocessor plug-in for Mac OS X (MThread.plugin) works
on multiprocessor systems such as Apple G5.
To determine the effect that the multiprocessor plug-in has on rendering speed, render a project using the plug-in,
move the plug-in out of the Plug-ins folder, render the project again, and compare the rendering times.
