Didn't know about the ice wraiths, that's interesting.
The frame rate in all the recent Bethesda games either built with the new Creation Engine or the predecessor the Gamebryo engine have the engine tick rate related to the frame rate, that means as the frame rate increases so does your movement speed and the physics becomes out of sync with the world which results in objects flying all over the place, this was a terrible problem for me in Skyrim, all you can really do is enable Vsync and set your refresh rate to 60hz, you can do this with Nvidia drivers by setting custom resolution/monitor profile.
It's really one of the worst parts of the engine, it's even worse at low frame rates where the world slows down and it feels like input samples do as well, everything becomes slow and inconsistent. I hope it's something they improve before their next big game, it seems unlikely given it's a problem inherent to the engine.
