Why is movie performance slow, choppy or stuttering for Tiberian Sun?
If you find that the movie performance is slow, choppy or jerky, try reducing the CD caching. For Windows 95/98: Click on the Start button. Then select Settings. Click on Control Panel Select the System icon. In the System Properties box, click the Performance tab. Then click the File System button. From the File System Properties box, click the CD-ROM tab. Note the Supplemental Cache Size setting so that you can reset the cache size if need be. Now set the Supplemental Cache Size to Small. This should have a marked effect on movie performance.
