The PC release of Horizon Zero Dawn has been rocky, to say the least. The former PS4-exclusive title has been suffering from several technical issues on PC like frequent crashes, stuttering, performance issues, and some graphical options not working as intended.

The developers at Guerrilla Games are aware of that and are working on a patch to fix these issues. The very first PC patch, update 1.01, was released today that addressed some of the crash issues (not all) and also brought some bug fixes. The patch is only 1.5MB in size and doesn’t fix every game-breaking error out there right now.

Guerrilla Games also released a statement saying that they are working on another patch that will release sometime next week which should fix the other major issues. The official patch notes of today’s update are mentioned below along with the list of known issues that the developers intend to fix with the coming update.

Horizon Zero Dawn PC Update 1.01 Patch Notes


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.
