You may experience poor playback quality when you view a slide show in Windows Photo Gallery by using the Pan and Zoom theme

When you view a slide show in Windows Photo Gallery by using the Pan and Zoom theme, you may experience poor playback quality. Some of the symptoms may include playback that is irregular or that contains glitches.

Note This problem only occurs for high-end video cards.

For video cards that have a Windows Experience Index Graphics and Gaming score of 5.0 or more, playback occurs at 60 frames per second. For all other video cards, playback occurs at 30 frames per second. The increase in the playback rate for high-end cards can potentially be too resource-intensive. This intensive use of resources causes the symptoms that are mentioned in the "Symptoms" section.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this problem, decrease the frames per second rate for Windows Photo Gallery to 30 frames per second. To do this, follow these steps:
