Vertical lines seen while playing Assassin's Creed IV on PS4?

[Euphoria14]

Got off a long chat session with a Sony technician and this is what we found. Someone who has a better idea than us please chime in and let me know if it sounds valid.

------------------


While playing Assassin's Creed 4 I see weird vertical lines coming down the screen and certain areas. This happens a lot when viewing water, especially in spots that would normally show reflections (Only when viewing from off the boat. I never see these lines when sailing the seas). I also sometimes see this within towns as well. They are of a similar color to what they SHOULD be, but they appear to look a bit transparent.

For some reason if I turn my characters direction the lines vanish. Then when I return to the previous view angle they come back.


Now, if I set the game to 720p the lines are gone. They only display when I play the game in 1080p. (BTW, HUGE difference once you set it to 720p)

I have also been unsuccessful in replicating this issues in other titles.



Could it be the 1080p patch that is causing this weird issue? It is all me and the rep could come up with.
