Symptom: Game freezes while in instances (Stormwind Stockade multiple freezes prior to first fight, again prior to Hogger) Also in Surmar City and other locations.
Edit: also good to note that prior to and after freezing : FPS is zooming along quite nicely at 70fps - and prior to update freezing issue did not exist.
