Crawls is relative. I'm comparing how it's handling rendered 3d stuff to starcraft. The primary problem, as you say, is not graphical but rather computational...lots and lots of unnecessary crap and then it doesn't manage its usage timing well either as you say. I still see very long and unnecessary delays after moving a unit though, before I am allowed to select the following unit. What is it calculating? The unit has already moved (so not rendering issue), animations are off, there's no reason it should be such a struggle to select the next unit but it can take up to a few seconds and definitely depends to an extent on map size...hmm.
