I'm on PS4 so my patch was 8.3GB. I started it this morning at about 11:30 and it only finished at about 21:00, but I was playing Bloodborne online in the background most of the day.
None whatsoever so far, very smooth as well. I think if there are going to be framerate issues it will only be during intense moments, especially in the second or third playthrough when slag with the combination of other elements come into play.
