Dragon Age: Inquisition is a huge, complicated game, so it's not really a surprise that the new patch introduces a couple of bugs as well as fixing a lot of them.
Especially on PC, Dragon Age: Inquisition players are reporting problems after applying the patch.
There are loads of Reddit threads on the subject of poor performance of the PC version in addition to the newly-introduced bugs.
Hopefully there are more people enjoying all the great fixes than are affected by the new issues. I haven't grabbed the update yet (Destiny, you know how it is) so can't comment. How have you all found it?
