News by Adam Siddiqui on Aug 31, 2020
Horizon Zero Dawn on the PC has not been doing well, with the game suffering from many bugs and issues. Guerrilla Games has been working on to resolve the many problems with a new patch now available.

The patch is detailed below and should resolve the many bugs and crashes players have been facing since launch.
KNOWN ISSUES
Some players are experiencing an out of memory error during the game optimization process.
Some players are experiencing graphical settings issues, such as Anisotropic Filtering 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 issues that are not yet solved on both the player-compiled lists by u/EvilMonkeySlayer and u/Rampage572 - thank you!
PATCH NOTES
Please note: These notes may contain spoilers!
Crash Fixes
Fixed a GPU resource leak which could build up over time and cause instability.
Fixed a GPU hang that caused a crash that could occur when Asynchronous Compute was used.
Fixed a crash when AI would try to aim at an invalid position.

PATCH 1.02 (HRZ-PCR 14/5887879 03:52 - SUN AUG 16 2020)
KNOWN ISSUES
Some players are experiencing an out of memory error during the game optimization process.
Some players are experiencing GPU-related hangs during gameplay. The improved diagnostic data collection added in Patch 1.01 and Patch 1.02 is aimed at making it easier to track these down.
Some players are experiencing graphical settings issues, such as Anisotropic Filtering or HDR not working correctly.
Some players are experiencing performance issues on specific GPUs or hardware combinations.
Some players with a non-Latin-1 codepage may have had their save games missing after Patch 1.01; we have a script that can help relocate the missing save games. Please reach out to our team here using “Report Other Issue” for support.

DAY 0 PATCH (HRZ-PC 596/5863656 09:58 - TUE AUG 04 2020)
Below are a few recommendations from us about what you can do to optimise your Horizon Zero Dawn PC experience. As always, your feedback and support is so appreciated!
Updating the Latest Video Drivers
Please ensure you're using the latest graphics drivers available for your card. Older drivers may cause graphical glitches or stability issues:
NVIDIA: 451.67
AMD: 20.7.2 (“Optional” / non-WHQL) or newer
Look out for new drivers released around launch that may offer further benefits for Horizon Zero Dawn on PC.
Initial Shader Compilation
In order to improve performance during play, we’ve implemented a one-time initial shader compilation before the game starts for the first time. This can take an average of 10-15 minutes for most systems to complete. Once it’s completed, you won’t have to do it again unless you make a significant hardware change or update your video drivers. We’re looking into ways to further optimize this process.
Known Issues
Anisotropic Filtering settings are not working. This is a high priority issue for us to resolve.
Some systems may experience a brief stutter during general world traversal, UI updates, quest updates, or camera swaps in cutscenes. This is a high priority issue for us to investigate.
Some animations are designed to only refresh at 30fps even if the game is running at a much higher frame rate. We are exploring how we can improve this with a future update.
Shader Compilation process does not properly verify remaining storage space on user PC and can result in crashes if the user’s storage drive is low on space (compilation process requires additional ~2GB storage space).
