Couple of things to watch out for;
Xsi doesn't mind loads of polygons so much as loads of polys split over
loads of objects. Try and merge wherever you can
Using XSI you're kind of spoilt in terms of model quality because it works
hard to prevent you from making crappy models as you model. Imported models
are another thing and there's a surprising - or not - number of sloppy
modellers out there. I'd take a couple of objects out and just have a look
see how well they're made, just to get a feel.
Many polys and ray tracing don't always play nice and slow start as you
describe is symptomatic of this. Try turning off all reflection and
refraction and see if that pause at the start reduces. If it does then you
need to tune your BSP settings.
Good luck.
