Horizon Zero Dawn’s PC launch hasn’t gone all that smoothly. While the game looks absolutely superb during its best moments, the overall performance and stability aren’t satisfactory, which has been causing a fair bit of frustration for players.

The good news is that developer Guerrilla Games is hard at work doing its best to improve the build, and that continues today with Patch 1.02, which fixes a number of known crashes and bugs.

Revealed over on Reddit earlier today are the full Patch 1.02 notes:

Crash Fixes

  • Fixed an issue where some players would crash during their first game boot when the ‘game optimization’ screen is active and they ran out of disc space.
  • Fixed an issue where some players would crash if they updated their video drivers after the game was already optimized previously.
  • Fixed an issue where some players would crash during gameplay because of memory incorrectly being overwritten.
  • Fixed an issue where some players would crash during gameplay due to a texture unstreaming bug.

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.

In addition to the notes, a short message from the development team acknowledges there are further issues that need fixing and pledges its commitment to sorting them.

Today’s patch follows on from Patch 1.01, which was similarly focused on improving stability.
