I was on approach into KMIA yesterday with storms around the airport and expected to see some control issues.  However, in very flyable weather, the roll motion on final was darn near uncontrollable without large and sustained control inputs which in turn induced an opposite roll.  I switched to APP mode on A/P and saw that even the autopilot was having issues with 30+ degree roll moments below 3000 agl while locked on the localizer.   

I use active sky for weather and it is set to realistic settings, however, no other aircraft shows this type of wild behavior.  I am also sure that the REAL aircraft does not do this when whithin operating limits, because if it did, they could never fly unless sunny outside.
