A flat reading at around 20fps creeps in once we trigger explosives in the sewers, while the high-rises of the factory plant still take a toll on PS4's frame-rate. It's a handsome boost then - but it must be stressed that we're still in the process of determining whether this improvement reflects the game's other stress-points on PS4 - such as effects-heavy battles.Īs things stand, the improvement is clearly tangible, even if the frame-rate still isn't 100 per cent ideal. It's a night and day difference at points. Across the breadth of our video below, a run of this area puts us at a fixed 30fps in places where the older version dwelled in the mid-20s. Starting at its sewers and working up to the rooftops, Bethesda delivers a notable boost in Corvega's overall performance level compared to the day one patch. Thankfully, we have some good news on this front. Based on its update notes, Bethesda singles out the Corvega factory as a focal area of gain on PS4 - a nightmare to play in its launch state, with drops to 20fps and under on the console. Stability issues, glitches and areas of performance are in the crosshairs this time - while Xbox One's patch is still pending. Fallout 4's patch 1.02 went live last night, a 512MB file that puts to rights some of the game's outstanding issues on PS4.
