If you have been searching for the phrase "Horizon Forbidden West update 1037 1580exe top", you are likely facing one of three situations: a cryptic error message preventing launch, confusion over the latest patch version numbers, or a search for the top optimization settings after installing update 1.037 (or related build 1580). You have come to the right place.
In this deep-dive article, we will dissect exactly what update 1037 (often labeled v1.037) and the 1580exe executable represent, how they interact with the game’s PC port, and—most importantly—how to resolve the infamous .exe top errors to achieve a stable, high-framerate experience.
Print this checklist or keep it open. Run through it in order:
Patch 1.038 introduced major performance fixes, especially for 40-series GPUs. Use these settings for max FPS at 1440p or 4K:
| Setting | Recommended Value | Why | |---------|------------------|-----| | Upscaling Method | DLSS (NVIDIA) or FSR 3 (AMD) | Best FPS boost | | Upscaling Quality | Balanced or Performance | Cleaner than Ultra Performance | | Frame Generation | On (if available) | Huge FPS lift in 1.038+ | | Texture Quality | Medium | VRAM saver | | Shadows | Low | Big CPU gain | | Reflections | Low | Major GPU gain | | Depth of Field | Off | Personal preference / FPS | | Motion Blur | Off | FPS + clarity |
Apply these:
🔥 "Top" tip: After patch 1.038, turn on NVIDIA Reflex Low Latency (if on RTX card) for snappier controls.
If you are playing via Proton (Steam Deck), update 1.037 introduced a regression. The 1580exe expects a Windows-specific memory management call that Proton 8.x does not emulate perfectly.
The top fix for Linux users:
For users who are comfortable with Command Prompt, you can launch the game with a process affinity mask that avoids the problematic CPU core.
This restricts the game to the first 8 logical cores (mask FF for hex). Many 1580exe top errors arise from core-hopping on Ryzen 9 or Intel i9 processors.
In crash logs, Windows Error Reporting often lists the faulting module as HorizonForbiddenWest.exe followed by a build number. In this case, 1580 appears to be an internal build identifier for the patched executable included with 1.037. Players encountering a crash with “1580exe” in the error details were advised to install update 1.037, which replaced the older executable (e.g., build 1570) with the newer 1580 version.
If not, restart your launcher or verify game files:
