As the quest to improve Horizon Zero Dawn on PC continues, Guerrilla has dropped its third major patch since the August 7 launch.
It's yet another lengthy patch with some provisos: alongside of the bug fixes is the implicit statement from the development team that there is more work to do. The currently known major issues are still very much on their radar (most notably the specific GPU/hardware optimization problems), and some crash fixes are already implemented as of today.
Two major GPU bugs (a resource leak and a hang) should shore up the general instability of the game, as well as at least four crashes that would trigger off of specific instances. The DLC area is also a little smoother (snow particles were giving players trouble in the past), as is the operation of 4K scaling (no need to go back to the menu to swap this back every time after booting it up).
There's more work to be done, but a lot of the legwork is done already. You can find recaps of 1.01 and 1.02 at the preceding links.
