You might get some really good answer's http://www.gamesas.com/forum/180-pc/, Though someone here might know also. About the same people. I'm on console, if you are I'd clear my Cache. Be worth a try.

There are plenty of mods that "fix" the long distance graphics, but they will lower your framerate.

Try updating the drivers to your graphics card.
