I've had to update all windows on a project.
Now I have to remove all shapes used to create patterning and all patterning. This is very painful and slow - 1 - 2 hours per elevation because of all the time spend regenerating the DV. This is where a static DEM would be better.
Flood would also help but complicated models and slopes blow that out.
No way to know for sure, but try turning off Forward View unification until you need it. Does that help performance any?
For reference, we are very close to posting an 8.11.7 update which should help address some of these performance related issues. If you fall into this category, it should be well worth installing when available.
Id did install another 4Gb Memory on this machine and that helped but this machine only takes 8Gb
Anxious for any speed
