Horizon Zero Dawn Complete Edition made its PC debut last year, paving the way for previous PlayStation only titles coming to desktop and laptop rigs everywhere. With improved visuals it took an already stunning adventure and added things like UltraWide support and more open-world detail. To get it running in 4K though, you needed a bit of a beast.

Today the game got an update (with Patch 1.11) which adds NVIDIA DLSS for improved performance and visual fidelity alongside replacing the use of FidelityFX CAS with the newer AMD’s FidelityFX Super Resolution. This removes the need for the previous resolution scaling needed to maintain 60fps.

As per the patch note below, there's also some improvements made to loading and the shader stuff.

Graphical Improvements

• Added Nvidia’s DLSS upscaling technology.
  
• Added AMD’s FidelityFX Super Resolution, replacing FidelityFX CAS.

UI Changes

• Adjusted settings screen to facilitate the addition of DLSS and FSR.
  
• Render Scale option has been removed but same result can now be accomplished by adjusting setting Upscale Method to Simple and adjusting Upscale Quality.

Performance Improvements

• Improvement to the shader management system. This will result in a few noticeable differences:
  
• There is no longer a shader pre-compilation step on startup. The game will always compile shaders during loading and in the background.
  
• Stutters during gameplay that used to occur due to background shader compilation have now been significantly reduced.
  
• Because shader compilation is still happening in the background you may notice the game having a higher CPU utilization while that is happening.
  
• Loading screens will wait for the required shaders to be fully compiled. This may cause loading screens to take somewhat longer on certain systems.
  
• On higher spec machines with faster CPUs the loading screens will typically be shorter, due to more efficient shader compilation that better leverages high-end CPUs.
