Video was captured on the module prior to the current version of the game. This issue has persisted since my original post and has yet to change. As far as out of the ordinary no. It occurred when update 1.1.0.13441 released and I loaded the save. That was the update that had problems and was rolled back and released again and the stuttering occurred in both releases of the update pre and post roll back. The stuttering only occurs when waiting in a city, traveling on the map and waiting for siege machines to build. The performance of the game is stable in the sense it does not drop overtime. The stuttering and performance remains the same throughout play.
Yes the stuttering happens on both graphics modes. I have also tried changing around the HDR settings and exposure to minimize shadows but that does not help either.
