Seen a few streams now (avoid opening parts to keep most spoilers at bay), and even in firefights with lasers and blasts going off everywhere, I can't recall seeing dips in FPS that were noticeable. Might be easier to see if not on twitch? However, the loading times are real. Like early Bloodborne. Both on PS4 and Xbox One streams.I'm reading that the PS4 edition is having some problems with dropping frames and general frames per second issues.
Edit: Should clarify, SOME PS4 owners are complaining. Not all.
