Yes, Depth of Field doesn't work as intended so far...
A bokeh depth of field filter is added, kicking in with cinematic shots during dialogue, plus on scoped weapons.
In its current state, it simply blurs the background, much like a gaussian form of the effect.
That must be fixed with a patch, i guess...
Actually it would be nice, if Bethesda would make a statement, for a new patch release. (after all those bugs in the PC and Console department)
