Making previews display more quickly (Photoshop)

The Use Pixel Doubling preference option speeds up the preview of a tool or command's effects by temporarily doubling the size of the pixels (halving the resolution) in the preview. This option has no effect on the pixels in the file; it simply provides faster previews with the tools and commands.

To speed up previews:

1. Do one of the following:
• In Windows or Mac OS 9.x, choose Edit > Preferences > Display & Cursors.
• In Mac OS X, choose Photoshop > Preferences > Display & Cursors.
2. Select Use Pixel Doubling, and click OK.
