has anyone experienced a "stuttering" phenomenon? flying between EGAC and EGGP at fl190, the acft suddenly started to stutter (similar to hic-cups) my frame rates varied dramatically between 25-36 in the VC view and over 65 in spot view.both views had the stuttering effect.hope that I dont need to uninstall and go through the process of re-installing again!thanksMel

Full names here please Mel. Usually, video stutter is due to the video processor putting things on hold while it catches up. There are a lot of ways to attack this, including playing with the sliders or dialing back the resolution of the VC via the configuration manager that came with it.

Check your anti-virus or other similar security software.I've forgot about scheduled defrags or virus scans when playing with FSX before...and wondering why I was getting really abstract and bad stutters.
