http://forums.fedoraforum.org – When I first got my Dell Latitude D830, I was getting very good performance with Fedora on it. This is especially true when I installed the NVidia drivers. But I noticed about two Fedora releases ago, that video performance began to drop and that when playing video, especially hi-def video, the video performance would drop and the video would get out of sync with the audio.
