Graphics Problems

[kl0wn]

I used to have the giant flashlight error, but I downloaded the latest ATI drivers and the 1.01 patch and that problems gone. The shaky textures glitch is gone too. I have other problems now though.

1. The artifact in the kitchen cupboard in the mess hall is giant now.
2. The floor is missing in the Sewers.
3. Doors are randomly missing sometimes.

I really don't know what to do. I had none of these problems with the tech demo or the Black Plague demo, what happened to the full version of the game?
