Improving performance for effects

Some effects are very memory-intensive. The following techniques can help improve performance when applying these effects:

Select the Preview option in effect dialog boxes to save time and prevent unintended results.
Change the settings. Some commands, such as Glass, are extremely memory-intensive. Try different settings to increase their speed.
If you plan to print to a grayscale printer, convert a copy of the bitmap image to grayscale before applying effects. Note, however, that in some cases, applying an effect to a color bitmap image and then converting it to grayscale may not have the same result as applying the same effect directly to a grayscale version of the image.
