Digital Foundry is reporting that the perceived frame-rate drops in Call of Duty Ghosts on PlayStation 4 are actually skipped frames.
They have discovered the game “runs at higher frame-rates than 60fps on a fairly frequent basis, despite the video output being limited to 60Hz.” This causes juddering and skipped frames which are “far more noticeable than the drops down to 50fps found in the 360 version of the game.”
The new patch which renders the game in 1080P has reduced – but not completely eliminated – the times when the PS4 manages to output over 60fps. However, the trade-off for 1080p is the game now drops the frame rate slightly more than when it was running in a lower resolution. Digital Foundry say “at worst we’re looking at a drop down to 40fps when the engine is more heavily stressed.”
It seems like the PS4 is rather more of a beast than we had thought, if CoD can get the PlayStation 4 running over 60FPS in 1080P at a launch, heavens knows what that PS4 will be doing in a few years’ time.
