A patch like v1.3.55.0 introduced major features, including and texture streaming improvements . In contrast, v1.0.37.0 was the foundational PC version focused on base performance and bug fixes.
A highly documented bug in earlier builds caused a performance penalty when users enabled NVIDIA Reflex in "On + Boost" mode. The 1.5.80 executable fixes this structural latency flaw. Enabling the feature now successfully reduces system latency without sacrificing raw frame-rate output. 4. Weather Effects and Environmental Geometry Fixes horizon forbidden west update 1037 1580exe

This update was part of the early post-launch "hotfix" cycle managed by and Guerrilla Games to address critical day-one performance and stability issues on PC. Key Fixes and Features Update 1.0.37.0 / 1.0.38.0: Early Stability
Initial versions of the PC port suffered from heavy VRAM allocation, sometimes causing sudden frame-rate drops (stuttering) when crossing rapidly into new map sectors. The update refines the texture streaming pipeline. By dynamically throttling assets based on real-time availability, it prevents the game from over-allocating memory, keeping performance stable even on cards with 6GB or 8GB of VRAM. 3.
