So I've had Skyrim for a pretty long time, and I really enjoy playing it. I come across the occasional minor bug, but it is never game breaking and might just be funny. Anyway, I've been having the same lighting bug ever since I bought the game, and it’s driving me crazy. I've turned off all of my mods (both one at a time and all at once), and it doesn't affect the glitch occurring. I have not been able to find any other instance of this happening to someone else, and I've looked pretty hard.
Essentially, in areas where either the lighting is coming from a hole in the roof, or my character walks under trees or in foliage, the lighting bugs out. It flickers and sometimes I even see this very faint grid-like pattern shifting around. For clarification, I have a video, but the forum won't let me link it here.
I have an ATI Radeon HD 3800 Series graphics card. If you need any other information, I would be glad to provide it.
Any help on this would be extremely appreciated, as it is distracting and takes away from the game play experience. Thanks!
