As mentioned by some reviewers, Call of Duty: Ghosts on PS4 has some issues with maintaing the 60FPS, and drops occasionally. However, that may not be a problem for long at all. Giant Bomb is reporting that Infinity Ward is working on a patch to fix the PS4 issues, and that the patch will be out ASAP.
I’m told that Infinity Wardis working on a patch to correct the performance issues. Currently, I’d call it a toss up between the Xbox One and PS4 versions–the Xbox One version has a smoother frame rate, but I’d rather play the game on a Dual Shock 4. Getting that frame rate pegged would definitively swing things in the PS4’s direction, even over the PC version, which is sort of a mess.
