SimLab Composer Pro

Hi
I recently purchased SimLab Composer and it works pretty well (almost great) with small architectural models. But it slows to a snails pace with a larger one I am working on. Next to unusable.
I have exported with .obj from MoI using medium density quads and triangles. It does not work with Composer for Rhino, either.
I have 16 gigs of RAM and two Nvidea Graphics Cards GT 640 and GT 670 and am running Windows 10 Pro.
Any suggestions?
thanks
eric
