To speed up the display, you can use commands on the View menu to turn off rendering quality features that require extra computing and slow down movies.
None of these commands have any affect on how Flash exports a movie. Use OBJECT and EMBED parameters to specify the display quality of Flash movies in a web browser. The publish command can do this for you automatically. For more information, see Publishing Flash movies.
Outlines Displays only the outlines of the shapes in your scene and all lines appear as thin lines. This makes it easier to reshape your graphic elements and to display complex scenes faster.
Fast Turns off anti-aliasing and displays all the colors and line styles of your drawing. This is the most common mode in which to work.
Antialias Turns on anti-aliasing for lines, shapes, and bitmaps. It displays shapes and lines so that their edges appear smoother on the screen. This option draws more slowly than the Fast option. Anti-aliasing works best on video cards that provide thousands (16-bit) or millions (24-bit) of colors. In 16- or 256-color mode, black lines are smoothed, but colors might look better in Fast mode. Also, note that Antialias has very little effect on a black-and-white display.
Antialias Text Smooths the edges of any text. This command works best with large font sizes and can be slow with large amounts of text.
