Horizon Zero Dawn on PC Finally Has Its First Patch


After some noted performance issues, the PC version of Horizon Zero has a new patch from Guerrilla Games to make some fixes and updates.

After several years of exclusivity on the PS4, Horizon Zero Dawn made its much anticipated debut on PC last week with a host of new features. While the game itself is a graphical showcase, numerous PC players have also noted that the port does have its handful of technical and performance issues during its launch week. Thankfully, some early changes and fixes have made their way into the game with one of its first patches, with more updates to come.

Developer Guerrilla Games has detailed that a new patch is available now for the PC version of Horizon Zero Dawn that brings a few improvements and updates to some of the noted technical issues present in the game. Specifically, patch 1.01 includes some fixes for startup crashes and performance issues related to specific GPUs or PC hardware, along with other specific software issues and hangups.

You can take a look at the full patch 1.01 notes for Horizon‘s PC version below:

Patch 1.01


In addition to the issues identified previously, we’re working on a number of high-priority issues:

Some players are experiencing startup crashes. Patch 1.01 fixes a few, but not all, of these crashes.

Some players are experiencing GPU-related hangs during gameplay. The improved diagnostic data collection added in Patch 1.01 is aimed at making it easier to track these down.

Some players are experiencing graphical settings issues, such as Anisotropic Filtering not working, 4K not displaying correctly, or HDR not working correctly.

Some players are experiencing performance issues on specific GPUs or hardware combinations.

We’re aware of and continue to investigate all issues in this list on Reddit as well. Thank you to u/EvilMonkeySlayer for compiling this for us.
