They do have it.
Shimmering is not effected by anything other then videocard/videocard drivers.
Most people just don't understand what it is.
It isn't the same as the AF reduced stuff that is mentioned above.
AF DOES NOT get rid of shimmering in LOMAC for Nvidia 6800 cards, you are correct BuzzU. What you and I are talking about is different then what Catseyes is talking about. He has it as well (if he has the same type of videocard) but probably doesn't notice it (many don't). The shimmering in LOMAC with Nvidia 6800 cards can only be dealt with by messing with the LOD/Mipmap (IIRC) levels. Same as FS2004 and late model ATI cards. Bumping up the AF levels does nothing. I, personally, happen to notice all the crap like like that. lol
