I have a performance issue with a big model. In model i have ~100000 TopoDS_Face and for each face i have an TopoDS_Shell. When i wan't to Orbit or Pan the view the frame rate is dropping to very low. When I create same likely model but with only one TopoDS_Shell and same amount of face, the Orbit and Panning is goes smooth.
Question: Is there a technical limitation for that or i do something wrong?
