Small architectual demo

hello,
i just made a small demo but i just want to know your opion in general and especially if it works or not. i want use this demo for my company as a promotion but im not sure yet. I dont use the GLSL shader just multi texture. In the next version i want to use shaders and add more stuff. I have a question to is there someone that knows how i can handle the load becaus even on my i7 intel it takes some time!

Nice. Looks pretty good for multi-texture mode. Some other screenshots would be nice.

i added to more screenshots there not much but this is because the demo is small.

i just take them outside the camera this is the reason that you see the overlay of another scene.
