Its going to be a comercial real time virtual application, to show off before-constructed buildings, rooms, and anything architecture related for presentations.
On the 3d part we will be using high poly models and some very high textures, what we want acheive is a high quality art work.
The programming side will get something like: use extensive of shaders, mouse and keyboard input for camera movement (walking), a GUI set, some sprites (billboards?), and thats all... no physics, ai, special effects, sound, etc...
The hardware part, is going to be a 2 processor machine (i dont know yet, but could be 3+ GHz) with 2g of memory and a 256mb video board (400/1100), so the hardware will be a high profile machine. (probably a quadro or nvidia related)
What we need to know is if ogre will handle good a very high poly count, and some big textures (~1k) with that machine spec. Can you tell me how much triangles he can handle ? Or a minimun - maximun of where he can go ? Can he handle as much as like, hmmm, half life 2? or some lower engine for a fps game?
Also, can you give me some pointers if i missed here. Like, what more i can spec for you guys about the project that can make you better understand it and give me some tips and ideas.

All help is appreciated, since im just starting out, and the project start is getting a lot near.

(sorry about the english)
