Machine specs:
Win 7 64 bit, 8GB RAM, Athlon 6 core 3ghz proc, ATI 6970 2GB RAM using driver 11.3 from 3/29/2011.
At my office, everything renders fine, but at home on the above machine I'm getting constant flickering with my textures. In this screencap you can see it affecting my helm: http://img708.imageshack.us/i/flickering.png/
It however is also greatly affecting terrain and I can see all the individual triangles used for the geometry while the flickering goes on. I've tried changing all my graphics options but to no avail.
