Microsoft Visio 2003 Performance Issues on Image Overlay
Posted on 2006-05-15
I have a user - one of our technical drawing staff - who is having severe issues with Visio performance, specifically when he imports a picture (jpg, typically) and scales it for use as a background or overlay in a drawing, then zooms into the drawing. The problem is worse the more he zooms; any actions taken can take several seconds to refresh onscreen.
The machine he is using is highly specced for his role; it is a P4 3GHz (hyperthreaded) with 2GB of RAM and a Matrox Millenium G650 video card.
Utilization on the first virtual processor leaps to about 60% when the problem occurs; for example, I zoomed into a document displaying the problem and used the nudge controls to move a line up and down; each nudge took about two seconds to refresh onscreen and the processor hovered around the 60% mark. Neither memory usage or page file usage changed appreciably.
I have attempted to use macros to control the ScreenUpdating and ShowChanges parameters, but these generally made the program unuseable.
Can anyone offer any suggestions?
