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
- []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)
