One door alone has a face count of 4409
No prizes for guessing where they all are
Loadsa round stuff everywhere with bazillions of vertices are the problem. Generally, 3 vertices = 1 face (assuming a triangle, which DirectX (which DB uses) uses).
Ditto:
Just select each object and apply MultiRes to them individually.
I'd do it myself, but you may be able to change some things, whereas all I can do with MeshSmooth alone is make stuff less round.
(Got the piccys of where all the vertices are by applying the MultiRes modifier, pressed Generate, clicked the little plus sign next to the light bulb & 'MeshSmooth', and clicked Vertex. It hilights all the little buggers in blue.)
2005 - Year of cartoony red cubes (look! black outline!), for me at least.
