Joystiq gave Call of Duty: Ghosts 3.5 out of 5 on PlayStation 4 and the reviewer talked about the frame rate issues saying: 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.
IGN also talked about encountering frame rate issues in their review saying: 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.
Edge gave the game a 7/10 and had the following to add regarding frame rate: While the PS4 version runs at a native 1080p, that precious framerate drops briefly before checkpoints, which are at least placed so that the odd stutter never affects gunplay.
GiantBomb also talks about these issues in their review saying: Additionally, the PlayStation 4 version has a handful of noticeable dips in its frame rate. This usually seemed to happen when a lot of smoke or other effects were on-screen, but occasionally it occurred in multiplayer for reasons I couldnt even guess at.
I am going KZ only next Gen this sounds not exciting.
