There's a lengthy thread on the LFS forums about graphics settings, might be answered in there...

Draw distance/resolution?
AA isn't the best way to reduce jaggies, resolution increases are
negetive lod bias would have fixed it, fixes it for me in nearly all games, but does cause severe texture smearing if not used with high ammounts of AF.Fixed it somehow.
I mssed with a bunch of nvidia panel settings and I think the Negative LOD bias setting helped it, I set it @ clamp, nvidia stock was ''allow''.
Also forced trilinear mipmaps.
Either of those 2 fixed it.
ive noticed this a fair bit, and a lot more in the railings on the side of the track on my old geforce, but on my radeon i dont get it at all. however, other people have reported the opposite, its all luck of the draw.
Well I certainly have enough GPU power for LFS, 16x AF is no problem at all.
Are you saying that one 8800 might have it and the other don't ? Meh!
