Online Docs : Expert Tab

The Expert Tab contains items that most people won't ever have to worry about, or at least will only have to worry about once.

FFT Library
This item no longer appears in the interface. All complex math is handled by the Altivec libraries.

Multithread / Multiproc
This turns on Fluid's multithreading, giving it tons more performance on a multi-proc machine. Even on single processor machines you may leave this option on. It doesn't hurt a thing for Fluid to be multithreaded on a single processor. This option is useful to turn off if you are using Fluid as your background during normal work on a multi-proc machine. That ensures that Fluid will never slow you down because it is, at most, going to be using one of your processors at a time (although it may jump between them during use).

Main Monitor only
This is a very important setting and, until Apple fixes the issues with multiple monitor support and OpenGL screensavers, will probably never be changed from the "ON" position. OS X screensavers that use OpenGL slow to a crawl if you use more than one screen at a time.

Use network themes if available
This option will only be enabled if you are running OS X Jaguar version or better. It uses Rendezvous technology that debuted with Jaguar to access Fluid Themes from other computers on your local network. These other machines must be running a Fluid Theme Server. If you would like to share your themes with other computers on your network just drop your copy of Fluid Theme Server in your ~/Library/PreferencePanes/ directory. You may have to create the PreferencePanes directory. Then run the System Preferences application and you should see the Fluid Theme Server (FTS) item at the bottom. Select FTS and start it up. If you want it to run automatically when you login, select the appropriate button. Now others should be able to use your themes.
