Notice the shadows on the ceiling of the dungeon; the flickering effect. I pasted my .ini file in the vid description. If anyone can suggest what is probably causing that to happen it'd be great.

You'll see them outdoors too. Any surface with actual textures in the mesh, like the brick walls. Everybody has a different opinion. Some say it has to do with AA, some say you have to disable it altogether, and some say they don't even notice it. I don't know. It's an awfully wide range. I can tell you how to disable shadows completely, but other than that, I can only suggest playing around with the settings.

However, you'll want to make a backup of your original INI (obviously), and then after you make your changes, you'll want to make a backup of that too. Furthermore, you'll want to launch the game directly from the TESV.exe, not through Steam. It seems that launching through Steam will automatically reset your INI and you'll see none of your changes in-game.
