Help, shimmering graphics and strange shadows. (picture)

[Muninnhrafn]

Either the resolution you recorded at is too low to get a good view of the issue or there's nothing going on.

Ignore the video until the stairs comes up at 00:21 mark. IT doesn't matter what settings I'm at, it's always shimmering like that. Or does the game just look like that? Like the effect on the stairs. Is that what previous poster was talking about with shadows?

update: https://www.youtube.com/watch?v=SvOhPKOgyb0 here is the perfect example. Anyone have any ideas whatsoever?
