My worst part in the ps4 version besides the occasional dc is the heavy load and the lagg it sometimes gets. Especielly in the later parts of the game. Freezes up during a fight and 1 min later its back and has progressed the fight without me seeing.
Besides that and the stat bugg (of co op partner which can be fixed by reloading) ps4 version works fine. Then again i guess the difference is that you two play local co op hence we play over the network.
Get any error codes during the issues?
