Yep, re-adding it brought the performance back in line to 5244. So the real question is, does this speedhack break anything? And if not then why remove it? I don't know if there's and discussion on it anywhere. And if there are no known issues, seems rather silly to remove it as it gives a pretty measurable boost to performance. For me it might not matter but for users who don't have as high end a machine as mine it could make a difference between playable and not.
