Hi,
very nice demo loco.
My FPS was bad, between 8-12 (P4 2.4GHz, 512MB DDR, GForce 5600XT) but something is screwd with my drivers and i just cant be bothered with windows reinstall so i guess you could add at least 10-15FPS to that if not more...
It all looks good, camera distance could be set to see a bit further and camera code gets all wierd in narrow places (also made my FPS go to a crawl in one very narrow place, in some yard betwen a house and a tall fence).

On the other PC (same config except its equiped with ATi 9200) FPS is 12 where on that first PC is 8, but this one doesnt show some shaders like that point light in the main menu...
Will test later on GF5200 and ATi9550

Keep up the good work
