Hey, I just played the Unreal 2 demo (ugh...why did I bother...), but I wanted to know if my fps were normal. I got around an average of about 45-50 with all the graphics at the high settings (no AA of anything else though) with my 1900xp, DDR333, and Ti4400. Sometimes when a lot was going down I'd go into the teens though...seems a little low to me.
Also, were those the real textures in the retail game? If so the game doesn't really have the great graphics I expected.
