I've been running Skyrim for a while now on low FPS, I have a low end PC, 3.2 Core 2 Duo with a shared memory NVidia GPU (benchmark score 103). However after tuning the settings the past few days I'v gotten it to the point where I was pretty impressed, I now have nice FPS on with nice draw distance in the open world. My problem is that the game falls apart inside forts - or any similar stone building, prime examples being the ratway/ragged flagon - I don't know why it's forts in general, as the game seems to do fine in caves, houses etc, however the wooden Jarl's longhouses also see a noticeable dip. But nowhere near as bad as forts, I've noticed that if a fort is has multiple floors anything above the ground floor will be really bad, often to the point of unplayable. (ever tried aiming spells at 5-10 FPS, ain't gonna happen) So basically I'm wondering if there's anything I could turn down that would help me with this without forcing me to play with lower settings in the rest of the game.
