You absolutely can tweak the graphics for better draw distance, more color/saturation, higher resolution textures, less detail fade... so don't tell me "you can't" when the rest of the world around you can and does.
if anything, the lighting in Skyrim is considerably WORSE than any of the previous games. So much bloom, so much contrast... it really looks quite horrible in some areas. Basically any dark area with a light.
I don't see it stutter at all with my NV ini files (which took hours to get right) so... sounds like a personal problem.
