I cannot thank the OP enough man ! This is exactly the reason I switched from TS3 . I wish I knew this back then , perhaps it would fix that game too. I have a beast of a pc and yet the stuttering was so ugghh. Now , Elelunicy asked about NormalMapDistanceDropScale . Changing this value would effect the rendering quality of the whole map currently loaded. Mine is set at -2 currently ( I play highest setting available). This so that there is no quality loss as I move my camera away from objects and sims.
