You may notice a new feature in Windows Vista named Desktop Composition.
If you are a gamer or power user you may benefit from freeing up unnecessary resources that are being used by Vista's visual styles.
Toggle Desktop composition on/off:
Ctrl+Shift+F9
I recommend disabling this and also setting the vista theme to "Windows Vista Basic".
These can be done by right-clicking on the desktop and clicking "Personalise" then choosing "Window Color and Appearance"
