When I'm about to enter Riverwood from the 'Whiterun Road' my FPS goes down to about 24FPS, but deeper I delve into the city, the FPS increases once again to 50-60FPS. I normally get 50-60FPS on Skyrim, but when entering cities/villages I'm taking a toll. Also from http://i28.lulzimg.com/7226719aab.jpg point of Whiterun, my FPS can drop to 24FPS! But it's only the stairs part, for a couple of seconds. Once I'm down in lower level in the city, FPS goes to 50-60 once again. I find it strange that it never goes under 24FPS. I find it strange that beautiful parts and full of life parts of the world can give me 50-60FPS while entering a small village it goes to 24FPS for a few seconds. What I find more strange is, that I tried lowering the settings, and it's the same thing. Maybe it's an unoptimazion issue?
