Hard evidence of the PS4's frame-rate lead for the retail release of Battlefield 4 - even with its 50 per cent increase in resolution it can typically command a 10fps+ advantage during our stress-tests.

The PS4's strong performance lead is the real clincher though; a wide 10fps margin flaring up for most of our campaign mode tests. The comedown hits, however, once you realise that neither platform can pull off a straight 60fps during the larger Conquest multiplayer maps, where most of the fun is to be had. Regardless, a clear-as-day recommendation still goes to the PS4 version, and while there are glitches on both consoles that need to be addressed, the embracing of seamless, behind-the-scenes updates should at least ease some of Battlefield 4's growing pains.
