📋 About This Mod

Engine Fixes for Skyrim Special Edition

A WIP skse64 plugin for Skyrim Special Edition to fix bugs and patch issues.

The majority of current work on this plugin (5. 0+) is being done by Ryan, who deserves more credit than you can imagine :^)

Installation

  • []Install the Part 1 zip as you would any SKSE plugin, be that through your mod manager or directly to your data folder.

The "_preload.txt" file is required to be in the directory if you want to use the memory manager patch, so if your Mod Manager warns you about it, make sure it gets added.
  • []Install the Part 2 zip by extracting it to your Skyrim SE folder (the three dlls should be alongside SkyrimSE.exe, etc)

    For configuration see the INI Settings below. The defaults should be stable for all users.

    If you prefer SSE Fixes' version of the same fixes to this one, you can install them together and Engine Fixes will automatically disable its conflicting patches :)

    INI Settings/Configuration

    EngineFixes

    • []VerboseLogging (default: false) - Enables more verbose logging in the log file.

      []CleanSKSECosaves (default: true) - Deletes SKSE cosaves with no matching save on launch.

      []DisableChargenPrecache (default: false) - "Precache Killer" function, duplicated from RaceMenu.

      []EnableAchievementsWIthMods (default: true) - Enables achievements when you have mods installed.

      []FormCaching (default: true) - Caches recently accessed forms. Similar to SSE Fixes.

      []MaxStdio (default: true) - Raises max file handle limit from 512 to 2048, which should fix "False Save Corruption" bug in most cases.

      []RegularQuicksaves (default: false) - Makes quick saves use the regular save handler.

      []SaveAddedSoundCategories (default: true) - Saves volume settings for mod-added sound categories to a separate ini file. This functionality is the same as Audio Overhaul for Skyrim SE's dll, but they will not conflict.

      []ScrollingDoesntSwitchPOV (default: false) - Makes it so using your scroll wheel won't swap between 1st/3rd person. See LE mod here

      []SleepWaitTime (default: false) - Lets you change the time it takes to sleep or wait. See LE mod here

      []SleepWaitTimeModifier (default: 0. 3) - The in-game default time is 1. 0; smaller values speed up the sleep/wait time, higher values slow it down

      []TreeLODReferenceCaching (default: true) - Requires FormCaching. Fixes the very slow Tree LOD function that causes framerate drops most noticeable in Riften. Similar to SSE Fixes.

      [*]WaterflowAnimation (default: true) - Decouples water flow animation from in-game timesc
