"A Digital Foundry employee went on NeoGAF to explain what went wrong with their PS4/Xbox One Battlefield 4 visuals comparison:
Here's what the persons said:
"The issue here is simple; Tom had a limited amount of time to capture this stuff and was not able to do so in a normal environment. If mistakes were made normally, it would be easy to go back and correct, but with the way this worked, it wasn't really possible.
Why so different? DF uses their own hardware for capturing while DICE were handing out Elgato boxes to everyone else. The DF hardware is actually much more capable but it works differently and, without the experience of working with these new consoles, I can see a situation where settings were dialed in wrong.
JackFrags used what DICE provided and probably didn't even attempt to change any settings which, in this case, turned out to be for the best."
