Geometric profile very slow with 3D Cuts

Using ORD Update 10 R2 on a DOT project.  We have noticed when viewing a geometric dynamic profile with 3D cuts of drainage systems or a bridge crossing the panning or zooming in the dynamic profile is very slow and the software is very unresponsive.  We are also having the same issue with Drainage & Utility profiles with 3D cuts of the proposed terrains or other meshes.

We have tested turning off the display of all references in the 3D model, as well as messed with different settings for the 3D reference visible edge settings (fast, low accuracy, etc.), but nothing seems to help with the issue.

 I am submitting a Service Request this weekend for the issue, but I was wondering if others have seen the same issue.  Thanks
