About Immersive Weathering: Tweaks
From ModrinthA high performance addon for Immersive Weathering, built to speed up weathering and growth checks, reduce memory usage, and keep your game smoother without changing gameplay behavior ;]
《▓ Immersive Weathering: Tweaks ▓》
《▒ What It Does ▒》
Immersive Weathering: Tweaks is a lightweight performance addon that makes Immersive Weathering's area checks, growth processing, and weathering logic a LOT less heavy.
Normally, Immersive Weathering creates a ton of temporary position lists and objects while checking nearby blocks. IWT replaces most of that with reusable packed templates and per-thread scratch buffers.
This substantially reduces memory usage and GC pressure in the affected systems, while also making the actual checks faster.
Quantified API safely prepares the known templates in the background during startup, while the main performance improvement comes from reusing those templates during gameplay.
Same checks, same order, same results. Just faster, lighter, and a lot less wasteful. Simple as that xd

Exact gains will ofc depend on your hardware, modpack, and how much chaos is happening around the player xd
《▒ Tiny Memory Cost ▒》
IWT keeps around 15.7 KB of shared template data and roughly 4.55 KB of scratch memory per active thread.
So yh, it keeps a few kilobytes around to avoid creating hundreds of megabytes of temporary garbage. Java's GC can finally breathe a little :DDD
