What do Various Areo Performance Settings do?

* Animate controls and elements inside windows:
* Activate windows when minimizing and maximizing: Controls animation effect when min/max a window
* Enable Desktop composition: Seems to only effect whether transparency is used on the desktop
* Enable transparent glass: Requires desktop composition to be enabled as well, but handles transparency
* Fade or slide menus into view: Menu animation effect enable/disable
* Fade or slide ToolTips into view:same as above with tooltips
* Fade out menu items after clicking:
* Show preview and filters in folder:
* Show shadows under menus:
* Show shadows under mouse pointer:
* Show thumbnails instead of icons:
* Show translucent selection rectangle: When selecting a group of files, whether there will be a shaded box or just a plain box.
* Show window contents while dragging:
* Slide open combo boxes:
* Slide taskbar buttons:
* Smooth edges of screen fonts:
* Use background image for each folder type:
* Use drop shadows for icon labels on desktop:
* Use visual styles on windows and buttons: Without this, you will be left with the 'classic' windows theme.. and then.. why use vista? I would say leave this alone unless you are on a very old computer or dont like the new visual styles.
