Polygon: ”Much has been said about the fact that the PlayStation 4 version of the game runs at a native 1080p, and while that may be true, the game did struggle to maintain a steady frame rate, especially in hectic multiplayer matches. The PS3 version of the game ran into similar problems, whereas the Xbox 360 version maintained a steady 60 frames per second.”
IGN: “On the current-gen versions Ghosts looks nearly identical, though I did encounter occasional framerate issues during the single-player campaign on PS3 and PS4.”
Joystiq: ”A key pillar of the Call of Duty experience has always been rock-solid 60 frames per seconds gameplay. On Xbox 360,
Ghosts maintains this mandate. The PlayStation 4 version, however, has noticeable technical issues, sometimes slowing to a crawl, particularly during set-piece moments with multiple effects. One specific moment I was able to replicate multiple times on PS4 was a campaign scene that ran smoothly on Xbox 360 and PS3, while the game chugged On PlayStation 4. These frame rate hitches happen throughout the campaign on PS4 and, in a series known for its Hollywood-inspired bombast, it detracted from the experience.”
