About filters and Flash Player performance

The type, number, and quality of filters you apply to objects can affect the performance of SWF files as you play them. The more filters you apply to an object, the greater the number of calculations Adobe® Flash® Player must process to correctly display the visual effects you’ve created. Adobe® recommends that you apply a limited number of filters to a given object.

Each filter includes controls that let you adjust the strength and quality of the applied filter. Using lower settings improves performance on slower computers. If you are creating content for playback on a wide range of computers, or are unsure of the computing power available to your audience, set the quality level to Low to maximize playback performance.
