Hi guys,   I've got some really bad lag going on. One thing I notice is that within Nordic temples (inc. Bleak Falls Barrow, Korvanjund Temple), my FPS drops from its normal 60 anywhere else and fluctuates anywhere between 30 to 50. There is nothing specific that causes this sudden lag spike: I tried turning the camera view to any dusty areas (i.e. in Korvanjund, the light in the ceiling of the third or fourth room where lots of dust particles filter through), any bright and dark areas
