I have a fairly complex model of a lens with a number of optical features, so there are a lot of surfaces/faces.  I normally run in shaded with edges mode, real view turned off.  This is crawling, most often just stating "generating graphics" down on the status bar, even when trying to edit a simple feature.  I could understand rebuilds taking a long time, but how do I improve the "graphics" speed.

I have a Quadro K4000 card, and normally run better than this.  Is there a setting to temporarily disable or adjust?
