I have been monitoring CPU usage on my dual Xeon machine running Photoshp CS2 and notice that it only uses one of the four processors (each Xeon behaves as two processors). That processor runs at nearly 100%, but the other three stay dormant. Total system CPU registers as only 25%.

Is there something I need to do to tell Photoshop to use all processors? I do notice that the multiprocessor plugin is in my plugins folder.

Thanks.

No, Photoshop comes with support for multiple processors. Unless you’ve removed the extension plugins, or aren’t loading plugins — then Photoshop will use the second processor whenever it can.

Of course, if you’re working on small images, then the additional processor usage will go by too fast to see.
