Vizard suddenly running slowly

[JMOwens]

Just as an update, if anyone's interested...I uninstalled the nVidia drivers and tried running Vizard off the standard Vista driver. Unfortunately, the jittering choppiness remains. As always, I appreciate if anyone else has ideas about what could be happening. Thanks.

Hi,

Just a thought, do you have the Aero desktop enabled? If so, does disabling it affect performance?
