Performance Preferences

Settings on the Performance tab tailor system compatibility. In most cases you should not change them. However, you may find them helpful if you have an older system or if you are experiencing specific video problems.

Field	Description
Playback Performance	RealPlayer uses this setting to optimize the performance of clip playback. Change this performance setting only if your computer seems sluggish or has problems while playing content.
Clip cache settings	To speed playback of frequently used content, you can allow RealPlayer to cache it, much like a Web browser does. Not all content is able to be cached, it must be properly created to do so. To change the default selections, click Settings... .
Enable cache	Enable or disable caching by checking this box.
Clip cache size	(Default is 4MB)Reset the size of your cache larger or smaller (minimum size is 4MB). To resize the cache, RealPlayer must restart. To clear out old material, click Empty clip cache... Emptying the cache does not shrink the file size, it only clears out the cached material. If you need to regain disk space, shrink the size of your cache or disable it.
Cache location	RealPlayer’s cache is always the RealPlayer installation directory.
Optimize Video Display	Enable or disable Use optimized video. RealPlayer takes advantage of optized video display technologys. If your video is acting erratically, it may help to disable the optimized video.
