I've been following this since it first started on the MOI forum as a plain model without textures. The textured version is perfect. It reminds me of a building that I grew up in.
How many polys are in the scene?
The demo runs fine on my 7300GT. No problems except for the front door, which has one or two polygons that are textureless and/or flipped. And in windowed mode, the top and bottom text is cut off a little, and the copyright can't be seen.
