So I'm running the game on my laptop, low settings with high textures and a few other improvements, at 60 fps most of the time. However, sometimes when I leave an indoors area into Skyrim, the fps will drop to 25 where before it was 60. Restarting the game solves it. As you can imagine, this is very annoying.

Anyone else experiencing this? I don't think it's a memory leak as the drop is too sudden.
