Well, excitement from reading this thread has dropped off significantly. Playing for a few hours consecutively is the real test and in a lot of cases it looks like it still hasn't helped very much. How depressing, wonder if there's any hope for another patch that's reasonably close, probably not
Was at ~50 hours in with a 7.3mb file, all autosaves disabled. Get the stutter after an hour and a half or so of playing, obviously I'm not in as much of a jam as you 10mb+ folks but I'm still holding out for a solid fix. Will update when patch goes live in NA.
