i am more curious whether they improved performance...
They listed stability improvements. Hopefully that means that the potential memory leaks have been reduced/resolved. Or whatever it is that causes some big drops. Personally I run the game at max settings at 1080p with 60-90fps avg. At times though it can drop to 37-40. Mostly and perhaps only on the tempest so far. While I think the game looks fantastic visually on PC it suffers greatly when you compare it to BF1 that runs at about 70-80 avg. at twice the resolution with max settings.
There is also some kind of loading bug where loading a save that usually only takes a few seconds can take seemingly forever. Hope they fixed the camera stuttering that occurs while using a gamepad and the hotkey assignments and profiles resetting each time you load a saved game. A save where you saved the hotkeys etc.
