Any of you that have problems with the animations and stuff like that?
example.

- Character sometimes starts to floats around. until it hits a wall or something, then starts to run again
- 15h played, not once has I been able to sneak upon someone and get the cut their throat animation., Character just cuts with sword instead
- 15h, No heads has rolled, no kill animation whatsoever including sword. Arrow and spells still works
- and a lot more.

Using any mods, by any chance? From the sounds of it you've got an animation mod of some description that's been broken by the patch, at least from the "character floats around" part. Not sure why killcam animations won't trigger; could be bad luck, could be a faulty mod, or it could be you're using that sword in your character's left hand. (Bethesda never bothered to do killcams for left-handers. Part of their continuing conspiracy to drive me absolutely stark raving mad.)

Using lots of mods, but none that should interfere with the animations.(as far as I can tell). Have FNIS installed, but not been used for ages..)
But then I take it you don't have this problem, so I have to look into my mods... hm..
