I picked up Skyrim today, and installed it on my very aged laptop (2gb RAM, 2.0ghz Intel core 2 duo, Nvidia GeForce 8400M GS). It runs quite choppy in areas of light, but I notice when I face a corner or dark corridor the frame rate improves dramatically. Anyway, I can't get a new laptop any time soon so I was wondering if there was any way to lower the quality of light in the game and increase my frame rate.
I have fiddled with every option in the launcher to no avail.
