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. Stability issues, glitches and areas of performance are in the crosshairs this time - while Xbox One's patch is still pending. 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. Thankfully, we have some good news on this front.
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. 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. It's a night and day difference at points. 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.
As for the rest of the game, we'll be back with more extensive tests on patch 1.02, checking whether a similar boost is in effect elsewhere. And of course, Xbox One is due for an equivalent update in the coming days, something we'll cover as soon once it lands.
