The game really does run terribly on xb1. Don't even try to play when inside the city around all the large buildings. I restart my xbox and it might run smooth for a few seconds before it gets all laggy again. I have the hardest time playing because of it. Sometimes if I use VATS, the framerate will drop to about 5 frames per second, no joke. Even in the woods far away from large buildings. Just unbelievable it passed testing and was released like this. Still love the game and want to play it, but just wished it was smoother.
