BootBoost

Decreases initial boot time by around 10-15 seconds.

Every time the game starts it has to decrypt the .bhd files in the game directory, which takes a surprisingly long time. Fortunately if you decrypt them yourself and replace the files it will just load them directly, which is what this tool does.
I recommend using with the No Logo Mod for maximum speed.

Installation

1. Drop BootBoost.exe into the game directory, usually "C:\Program Files (x86)\Steam\steamapps\common\DARK SOULS III\Game"


2. Run it.

Uninstallation

1. Restore the original files from the "BootBoost Backup" folder.
