Despite the fact it runs at a higher resolution than its Xbox One counterpart, there have been a fair few performance issues with the PlayStation 4 version of Call of Duty: Ghosts. At times the game appeared to drop frames, or suffered from drops in frame-rate. When Eurogamer's fantastic Digital Foundry section decided to investigate, they discovered something fairly interesting...
The issues were caused by the PlayStation 4 running the game at a higher frame-rate than necessary.
So just what is going on? Well, a close look at our captures reveals that Call of Duty: Ghosts actually runs at higher frame-rates than 60fps on a fairly frequent basis, despite the video output being limited to 60Hz. In scenes where we experienced judder and perceived frame-rate loss, what we are actually seeing is the appearance of skipped and incomplete frames - an effect that is arguably far more noticeable than a few prolonged drops down to 50fps or so seen the 360 version of the game.
Amazing spot by the Digital Foundry team. Can't believe that a game is having issues because the frame-rate is running too high. Hopefully it's something that can be fixed in a future patch.
