Thank you for taking time to download and endorsing this mod.

What is this mod


This mod is for those having a massive fps drop issue when you use the ELFX mod with the SMIM mod and ENB together. The latest ELFX had optimzed most of troubled areas, but it still struggle with some previous shadow casting light optimization not related to SMIM (colored in green), and those will also boost fps with just ELFX without ENB or SMIM.

Here’s the list of areas that got patched with this mod:
  • Jorrvaskr basement
  • Solitude Radiant Raiment
  • Faldars Tooth 
=== General ELFX light optimizations ===
  • BlackreachCity: the gigantic red ball - almost 100% gain (lower than 24fps to above 50fps with ENB, 36fps to 60+fps without ENB)
  • Folgunthur: Optimized 3 shadow casting lights for 20 to 30% gain.
  • Riften Haelgas Bunkhouse: 10% to 56% boost.  See the Recommending mods section.
  • Mzulft 2nd floor(coc mzulft02): 58% boost (38fps to 60fps).
  • Ysgramor’s Tomb: 42% boost (42fps to 60fps) The ELFX blue light on the Flame of the Harbinger.
  • Windhlem CandlehearthHall optimized: 15% to 35% depending on your GPU.
  • 36fps to 42fps on single R9 380, 42fps to 56fps on single GTX 1070
  • Dawnguard Redwater Den Spring: 20% boost (46fps to 56fps)
  • Whiterun Dragonsreach light on/off flicker as you pan your view.

WIP


  • Ustengrav 2nd dungeon: The shadow spot light shining the word wall is lowering low 40fps.
  • Shadow Green Cavern: The SSE mod optimization to this mod.
  • Dawnguard Arkngthamz: The top area still struggled at low 30fps near the Zephyr bow.

Mod load order


==== ELFX v3 ====
Make sure you activate this mod's Skysan_ELFX_SMIM_Fix.esp after the ELFX vanilla mod.
If ELFX is missing or not active, Skyrim will CTD if Skysan_ELFX_SMIM_Fix.esp is active.
UPDATE: Seeing both ELFXEnhancer.esp and ELFX - Hardcore.esp did not edit any ELFX lights this mod has modified, please activate this mod soon after the "Core" EnhancedLightsandFX.esp file.  You can activate ELFX options after this mod to use those optional ELFX settings.
If you have merged ELFX mod and options, you may need to merge this mod to that merged mod.

Merging ELFX and this mod ESP files


Not recommending this, but I was able to merge ELFX v2.0 and this mod v1.4.1, but It literally merged (created clones) on Ustengrav and Folgunthur. This mod's v1.2 edits were merged correctly. Here's how I merged.

  1. Installed xEdit 3.0.33 which is TES5Edit beta: http://afkmods.iguanadons.net/index.php?/topic/3750-wipz-tes5edit
  2. Installed the Merge Plugins xEdit Script mod v1.75 to xEdit 3.0.33. http://www.nexusmods.com/skyrim/mods/37981
  3. Used the fresh copy of ELFX v2.0 "CORE" EnhancedLightsandFX.esp file and this mod’s latest v1.4.1.
  4. Followed the Merge Plugins xEdit Script mod's "Merging Plugins:" tutorial, and took 6 minutes to complete on my PC.
  5. When exiting xEdit, I only selected the new merged ESP file to update only that file. I don't know why it selected ELFX and this mod ESP file in addition.

Merging mods without conflict vs TES5edit Merge Patch for conflicting mods


This mod uses the ELFX mod as a "master" file, so this mod won't conflict with the ELFX mod.  Here's STEP wiki guide on merging mods without conflicts vs TES5Edit Merge Patch for conflicting mods.

How did this mod fix


=== General shadow light optimization ===
The shadow calculation is done through CPU in the Skyrim engine, and the ENB adds more calculation for the realistic and better shadow casting.  ELFX's goal is the maximization in visual, so it pushes the Skyrim engine limit.  Some ELFX shadow lights have the "No Fade" setting, and the shadow calculation will ignore the room boundary optimization.  While still keeping the ELFX visual quality as closely as possible, this mod optimized those lights to that boundary if Bethesda had one included (i.e. mzulft02), and limit the "No Fade" setting usage when not required (i.e. Dawnguard Redwater Den Spring)
