For me, this is not the only interface issue. For example, all of the Options buttons and sliders do not exist. The only way I can adjust is via pref file.
I personally have not been able to play the game as I continue to CTD. I was only able to even get in (sporadically) when I turned off the intro. But I experienced the above interface issues, flickering, etc.
Is the mipmaps option something I can adjust in pref file?
By the way, I have three laptops. All different. Two experience the above. One seems OK but it is not one I can regularly play the game on now and not one I would use in the future. (The one that works is a Dell Latitude with standard drivers).
