"I have recently upgraded my graphics card from a nVidia GTX460 to an AMD 7850. Now, when I try to run LoG I cannot see the textures for walls at all, though I can see light sources such as torches, teleports and skylights, even if they aren't in the room with me. I do bump against walls when I move into them, they just don't reflect light, so to speak.

Has anyone had this issue, and do you know how to fix it?

Many thanks in advance!"

<EDIT>

Cannot delete so I'll just answer myself. Must have been searching for the wrong things on the LoG thread. Needed to turn off AA and AF. All back to normal. Sorry for the bother!
