When ‘horizon forbidden west’ crashes on startup for ROG Ally laptops, incompatible or outdated graphics drivers may be the root cause. Updating graphics drivers via the ROG Live Service or the NVIDIA/AMD websites often resolves the issue. Additionally, ensuring the latest Windows OS updates and game patches are installed can help stabilize the software environment and prevent crashes.

Insufficient system resources can also trigger crashes. Verifying that the PC meets the minimum system requirements for the game, including RAM, CPU, and GPU capabilities, is crucial. If necessary, upgrading hardware components or closing unnecessary programs while playing can free up resources and improve game stability.

If the above measures do not resolve the issue, consider performing a clean reinstall of the game. This will remove any corrupted files or settings that may be causing the crashes. Additionally, manually deleting the game’s temporary files and registry entries before reinstalling can ensure a fresh and stable installation.
