This isn't my video but i've got the exact same problem. Its most noticeable looking north towards the sea beyond solitude/dawnstar.In fact, whenever i can see the coast from anywhere in skyrim i can see this bug.It must be linked to 'reflect sky' in the launcher because unticking that box stops it, but then water looks rubbish. Anyone know why this happens and how i can fix it without turning off all water reflections.
thanks
im using the latest driver on gtx 560 ti 1gb. Everything but shadows are set to ultra and it's pretty much locked at 60fps, so i don't understand the problem.
...oh and i have the amazing flickering mountain glitch. Funny how i played this game on xbox 360, a 6 year old piece of c**p for over 60 hours without any of this s**t.
