I noticed that when DB is showing on the screen, that the stuttering somehow seems worse than when the db-screen is completely hidden by the diablo screen. I am not sure I am not imagining things and I am curious about other users' experience. But what really interests me is whether people with a fast internet connection (50Mb/s or more), also experience stuttering. This, because it also seems to me that it gets worse when more than one instance of diablo3 is running. As you see, this is no simple matter, and I hope other people will be willing to share their experience.
