Guide Scope

This guide is intended to be a general guide to the configuration settings for The Elder Scrolls V: Skyrim game as set through INI files, including Skyrim.ini, SkyrimPrefs.ini, Plugin INIs, and Mod Organizer (MO) INI Tweaks. Its purpose is geared toward how these will affect the game rather than being a comprehensive resource. See the advanced Skyrim INI and SkyrimPrefs INI guides for an advanced and comprehensive review of the configuration settings.

Terms

  • Default Value: The value for the configuration setting stored inside TESV.exe. For settings used only by the SkyrimLauncher.exe (i.e., sD3DDevice, uLastAspectRatio, bShowAllResolutions, and bEnableFileSelection), the value as initially calculated by SkyrimLauncher.exe.
  • Default INIs: Blank INIs, which upon load of the main TESV.exe Skyrim executable, the Default Values stored in TESV.exe shall be used. Default INIs with all relevant settings and their corresponding default values can only be approximated for floating point (f-prefix) and color (r-prefix and some s-prefix) configuration settings.
  • Default INI preset: The Skyrim_default.ini located in the main Skyrim directory and the SkyrimPrefs.ini located in the extra Skyrim directory inside the main directory.
  • Launcher INI presets: The low.ini (low preset), medium.ini (medium preset), high.ini (high preset), and very high.ini (ultra preset) inside the main Skyrim directory which the Launcher applies against the Default INI preset.
  • Base INIs: The standard game INIs generated in %UserPofile%/Documents/My Games/Skyrim after the first launch of Skyrim.
  • Plugin INIs: INIs loaded with like-named plugins (just like BSAs). Presence should be indicated by the paperclip on the plugin within the plugins list (right pane).
  • MO Profile INIs: Mod Organizer's profile-specific INIs created using the Base INIs.
  • MO INI Tweaks: Mod-specific INIs that exist inside an INI Tweaks folder at the top level of the mod folder for use with Mod Organizer. They can be enabled or disabled.
  • MO INI Tweaks Composite: The temporary combined INI Tweaks generated by Mod Organizer from combining the enabled INI Tweaks into initweaks.ini inside the profile's folder at runtime.

Recommended Changes

This guide assumes that the user has either followed the current STEP Guide or has jumped over to this guide whilst following the main guide. Note that this guide includes all INI tweaks recommended by STEP, including those in the STEP Guide.

The following instructions expect the unedited default INIs! If the INI files have already been edited, please delete them from %USERPROFILE%\(My )Documents\my games\skyrim and .\Mod Organizer\profiles\. After deleting them, the default versions can be regenerated by running the Skyrim Launcher again (run via MO if using MO). Template:Warning Small

Some of the tweaks are only relevant to the STEP "Recommended System". For tweaks that affect game performance the potential performance impact is indicated. Create the following at the end of each of the indicated INI sections. Sections are marked by names within square brackets '[ ]', and some of these sections may already exist, but for those that do not, create the section. Carefully check that ...

  1. no duplicate entries are created,
  2. that all entries are placed into the correct section, and
  3. that all sections are properly defined:
