Horizon Zero Dawn PC Patch 1.03 Available Now, Crash Fix & More Included

Guerrilla Games has published recently the patch 1.03 of Horizon Zero Dawn on PC, which goes to fix further bugs that have caused some problems to the players since the launch or that have started to occur with the previous updates released.

Among the crash fix, we find a fix for a leak of the video card resources, for a crash caused by a problem of GPU, for a crash caused by artificial intelligence, a crash caused by the sound of Horizon Zero Dawn, and the shift to a different monitor with different DPI settings in the menu.


Also fixed a progressing issue where Aloy would get stuck in a certain state during the start of the adventure of Horizon Zero Dawn, thus preventing the player from moving forward. There is no shortage of functionality fixes, when for example the snow deformation did not work correctly or when a certain skill did not work.

For the complete Horizon Zero Dawn patch notes 1.03, which deepens in detail the news of this update, you can refer to the official page of the website, present in the tweet at the bottom.
