The PC version of Horizon Zero Dawn is getting another update in the form of patch 1.02 which fixes some more of the port’s issues. This patch follows soon after patch 1.01, which was a smaller update that didn’t fix much.
Horizon Zero Dawn Patch 1.02 Fixes Some Crashes On PC
Developers Guerrilla Games released the patch notes on their website, as well as in a post on the r/horizon subreddit. “This patch aims to resolve some of the more frustrating crashes we’ve been seeing since launch,” it reads. Patch 1.02 fixes a number of the game’s issues which caused the game to crash.
One of the more notorious bugs was that the game often crashed when the players started it for the first time. This would specifically happen during the “game optimization” screen if they ran out of disc space. If the player updated their drivers for their graphics cards after optimization, that also crashed the game.

The game also crashed because of memory issues and texture streaming issues at times. If you’re one of the players experiencing these problems, this patch should take care of that.
Latest Horizon Zero Dawn Patch Contains Other Minor Improvements
The patch also contains other minor improvements. Here they are:
Game Improvements
- Improved performance when auto-saving (e.g. when completing a quest step).
- Fixed an issue where some players experienced that V-sync wouldn’t properly turn off in borderless mode
- Fixed an issue where some players experienced out of sync facial animations due to them being locked at 30FPS.
- Reduced memory used when streaming shaders.
Other changes
- Improved crash report flow and messaging. Each crash now includes an identifier you can use to communicate with our Customer Support.
- Added more features to improve diagnostic data collection when submitting a crash report.

Horizon Zero Dawn’s PC Port Still Has A Way To Go
While this patch does address some of the PC port’s issues, it doesn’t address all of them. They did list a number of issues that they know of and are currently working on. These include graphical issues, as well as GPU-related hangs. It’s likely that Guerrilla Games will have to release a few more patches before the game runs stable for everyone.
