Try setting undos to 0,
Set active layer to Top/2D View,
Set rendering to Wireframe,
Activate one layer at a time,
Work locally, not on a network-based file
Edit or draw from within a group or a symbol, so that you are otherwise isolated from the drawing file.
If any of these suggestions help, then the drawing or layer is too complex or VW is constantly trying to render.
Curved polygons (site contours) take up lots of processing time for me. So do complex 3d objects.
