I am running on a Nvidia GeForce 7800GT, AMD Athlon 64 3200, and 1GB of RAM. This is what the game looks like...

As seen in the picture there's a giant blob of darkness that prohibits me to see. The walls are pretty messed up as well. And where's the trees and rifle?

EVERYTHING is on low and anti-aliasing is OFF. Do I need to tweak the settings? Or does my rig just plain suck and this is what it looks like for everyone else with these comparable settings.
