📋 About This Mod
FROST FPS Fix!
This mod fixes the huge plummet in fps for FROST Survival Overhaul around areas like downtown Boston and Lexington and the like. That being said...
Incompatibilities
Not for use with the vanilla game for obvious reasons. This is an unofficial patch for naugrim04's mod, FROST. (v0. 55 as of 7. 0 of this fix)
Any mods that alter worldspace may conflict. Texture mods without any additional worldspace edits should not be an issue.
Installation
Drop the "FROSTfix.esp" and the "FROSTfix - Main.ba2" in your Data folder wherever you have Fallout installed or install with your preferred mod manager, activate the esp in your load order and place it below FROST's esp.
A targeted performance patch for the FROST survival overhaul in Fallout 4, addressing severe frame rate drops in urban zones. With 2,158 endorsements and over 101,000 downloads, it's a community-approved fix for players struggling with stutter in downtown Boston. Last updated in 2019, so compatibility with current game versions is unverified.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved fix with 2,158 endorsements and over 101k downloads
- Directly addresses the worst performance killer in FROST—urban stutter
- Simple, focused patch that does one job well
⚠️ Cons
- Last updated in 2019—may not work with current FROST or game patches
- Only fixes urban FPS; other performance issues remain untouched
For FROST players who love the brutal survival experience but can't stand the slideshow in downtown Boston. If you've already got the mod and suffer from stutter, this is a must-have. Skip if you don't use FROST or if you're on a rig that handles urban areas fine.
💡 Beginner Tips
- Load this patch after FROST in your mod manager to ensure it overrides the original files.
- If you're using a mod manager like Vortex, deploy and sort your load order to place this patch near the end.
- Test in downtown Boston (e.g., near Goodneighbor) to see the FPS improvement immediately.
