I'd like to start a thread containing your suggestions for optimizing computer systems for performance when using Audition. We'll link to this article from our blog and community help, so if you have a few minutes to share your own tweaks and discoveries they would be very valuable to other users. I'll try to keep an updated index in this post to help folks jump right to specific tips. For many issues, I intend to record short video tutorials which I'll link from this page as well.

Video playback is slow
First, make sure the driver software for your graphics adapter is up-to-date and preferably the manufacturer drivers and not the default Windows drivers. Try the following links, depending on the manufacturer of your graphics card:
The default drivers that accompany Windows are generally of a reduced set of functionality and may not have the most recent support for OpenGL and other graphics acceleration technology that is used by Adobe applications.
Next, make sure OpenGL and other acceleration technologies are enabled in your driver setup. Typically, these options are accessed from the Display section in Windows Control Panel.
Audition relies on Quicktime for much of its video format support, so be certain that Quicktime is up-to-date and in good working condition.
Make certain that no other applications are interfering with or using up system resources. If another program is accessing the hard drive (eg. downloading, rendering, copying files, etc.) or eating significant CPU or RAM (rendering, editing large projects, etc.) that leaves fewer resources for Audition to stream and play video. When resources are scarce, Audition balances its resources to maximize audio performance by reducing video performance.
