I haven't played Skyrim in months, and I recently re-installed it after hearing about the several updates that were offered. I'm currently up to date with a fresh copy, the game set the game to High-Quality, but I changed it to Medium.

The issue I've been running into is that in dungeons I get this horrible lag, and it seems to happen in large rooms OR in rooms with active lighting, such as candles, shadows, etc. But in the outdoors shadows/candlelight doesn't seem to disturb my system. My system meets all the minimum & recommended requirements for the game, and I was wondering if anyone had a fix or knew why this happened?
