A little update:
It looks like the another thing that does make a difference is adding "iFPSClamp=60" under the [General] section in the Skyrim.ini. This seems to virtually eliminate stutter entirely. The pretty significant downside to this approach is that if the FPS ever drops below 60 the game engine "slows down" making everything seem to go into slow motion. From what I've read, it seems that this setting 'locks' the game engine to the number you place after it. Go below it and you go into slow motion, go above (which isn't possible with Vsync and a 60hz monitor) and you go into fast motion.
Because this setting had such a strong impact, it seems likely Skyrim's stuttering is a problem inherent to the engine.
Still, if there is anyone else out there with fixes that I could apply, I'd be grateful.
Oh my god. I have the exact same problem and iFPSClamp=60 completely eliminates the stutter. Thank you!
