The early reviews of Call of Duty: Ghosts--includingmine--mentioned that the PlayStation 4 version of the game suffers from occasional frame rate issues. For me, it usually showed up whenever there were a lot of particle effects on screen, but it'd pop up at random, too. I'm told that Infinity Ward is working on a patch to correct the performance issues.
