760 27. Configuring ProShow: Preferences

Direct Draw Support is enabled by default in ProShow. Direct Draw is
Microsoft’s standard rendering method in Windows. Your desktop and
other elements of the programs you use on a daily basis are displayed on
the screen using Direct Draw. This method speeds up the process of
drawing things on your screen.
What this means, in short, is that working in ProShow will be faster and
smoother with Direct Draw enabled. If you turn off Direct Draw Support,
you will see slower performance. That’s because when Direct Draw is
disabled, ProShow must use older, slower methods of displaying things on
the screen. The basic rule is this:

Using Direct Draw is fast. Running ProShow without it is slow. Unless you
have a deeper technical problem on your PC you should always leave
Direct Draw Support enabled.

Video Importing is where you can configure how ProShow works with the
video files you use in your show.

Video Importing is enabled by default. This means ProShow will import
video files using its own tools, not external video codecs. If a particular
video isn’t working, try toggling this off. When disabled, ProShow will use
the codecs installed on your PC. Keep In mind, this means your codecs
must be installed properly.
