Howdy, My screen jumps around alot while im panning around. Doesn't matter if I'm close up or far away. I remember this being a smooth pan. Anyone have any ideas as to what might be the problem? specs: XP AMD Dual Core 2.01 GHz 3.0 Gigs Ram GeForce 8800 GT Virtual = 4000 I've patched up as well. So, any help will be appreciated.
