Preparation

Installing Protontricks

We will need Protontricks in order to manage and install closed-source Windows components that are not included by default in your Fallout: New Vegas installation. Installing Protontricks is as simple as clicking here and then clicking Install.

Install Steam Tinker Launch

You will also need to download Steam Tinker Launch. Steam Tinker Launch is an app that trivialises many complicated tasks that include but are not limited to
  • Installing mod managers
  • Installing ReShade shaders
  • Managing per-game custom versions of Proton
  • Applying per-game tweaks

Once you have installed Steam Tinker Launch you must not uninstall it. Later in this guide you will use this utility to manage your Mod Organizer 2 installation.

Uninstallation of this utility will render you unable to launch Mod Organizer 2.

We will be using it in this guide to install and manage Mod Organizer 2. Installing Steam Tinker Launch is easy but requires the light use of the terminal, to do so

  1. Download the latest release from GitHub to your Home folder. Advanced users may instead choose to clone the repository.
  2. Extract the downloaded .zip file as shown
  3. Extract SteamTinkerLaunch to your Home directory
  4. Open the newly created steamtinkerlaunch-master folder.
  5. Press Alt + Shift + F4 To open a Konsole window in the steamtinkerlaunch-master folder
  6. Paste the following command into the open Konsole window. This will add Steam Tinker Launch to Steam.

Installation

Installing the Game

Where should I install the game?

Opposite to Windows, you should absolutely install Fallout: New Vegas on your device's internal storage, in the default location.

If you have never installed the games before, go directly to step 5.

  1. Click here to be taken to Fallout: New Vegas' page in your Steam library
  2. Click the Settings icon, then click on Manage > Browse local files
  3. Delete the entire contents of the game folder.
  4. Click here then click Uninstall
  5. Click here to install Fallout: New Vegas

Post-Installation

Key Terminology

Now that the game is installed, there are two folders from it that will be referred to in the guide often:
  • Root folder: Where the game is installed.
    • ~/.steam/steam/steamapps/common/Fallout New Vegas

  • Data folder: Where all of the game's assets are located.
    • ~/.steam/steam/steamapps/common/Fallout New Vegas/Data

  • Prefix folder: Where all of the game's compatibility files are located.
    • ~/.steam/steam/steamapps/compatdata/22380

Generating Fresh Configuration Files

  1. Click here to run the game from Steam
  2. Allow Steam to generate a Vulkan shader cache. This will take a few minutes.
  3. Click OK to both pop-ups that say Detecting Video Hardware.
    • If there aren't any pop-ups, try re-installing the game, and then try again.
  4. Click OK then Exit.

Installing Windows Components

There are a number of additional components and libraries that are installed by default on Windows, but must be explicitly installed when you are using a compatibility layer like Proton. We will use Protontricks to install these essential components.

Installing the components is easy but requires the use of the terminal, to do so

  1. Open Konsole from the App Menu. You may search for it or find it under System > Konsole
  2. Copy and then paste the following command into the open Konsole window with Ctrl + Shift + V
  3. Wait for the installation to complete. It will take approximately 5 minutes. You will know it is complete when the text stops scrolling down the Konsole window.
