This mod is primarily a fix for a problem with Sim Settlements, and other incredibly script heavy mods. However, many people have reported increased stability and performance with it, so feel free to try it for yourself. Having a larger sample size to report their experience with it can't hurt anything.
The plugin is version independent and should work with any version of Fallout 4 that has an Address Library available.
FAQ: Q: What's the problem Sim Settlements causes? A: The game allocates ~70mb of memory when reading script properties and normally that's more than enough for the vanilla game, but Sim Settlements eats a ton of that, and with too many city plans, the game won't load saves anymore. This plugin doubles, triples, or quadruples that memory allocation to ~130mb, ~200mb, or ~270mb.
Q: Will this mod help with x, or fix x? A: I don't know, maybe? This patch will affect many things, and I don't know the full of extent of what it'll affect, and whether it'll cause problems or fix existing ones. Let me know how it works for you, if there are problems I can look into them, and if there aren't- that's great.
