Hi! I installed Doom3, downloaded the demo and followed the instructions. Everything seem to work fine except the fact that there's no texture on the ground and houses. I can see only some lit objects. So it is not playable for me. This is probably some driver issue or... who knows... My system is E6750, GA-P35-DQ6, 2GB RAM, 8800GT 1GB, Vista 64-bit. It might be Vista's fault? Thank you!
