Facts

Purpose: FerriteCore is a coremod designed to reduce Minecraft RAM usage.github.com · 1 Oct 2026
Optimization focus: The mod optimizes memory used by block states, models, predicates, strings, voxel shapes and baked quads.github.com · 1 Oct 2026
Blockstate neighbors: Replacing per-state neighbor tables with FastMaps saves around 600 MB in the documented test.github.com · 1 Oct 2026
Property storage: Replacing ImmutableMap blockstate property storage saves around 170 MB in the documented test.github.com · 1 Oct 2026
Model predicates: Caching multipart model predicates saves 300–400 MB in the documented test.github.com · 1 Oct 2026
Model instances: Deduplicating multipart model instances reduces about 200,000 instances to about 1,500 and saves close to 200 MB.github.com · 1 Oct 2026

Quad deduplication: Quad deduplication reduces baked-quad memory by close to 150 MB in the documented test.github.com · 1 Oct 2026
Purpose: FerriteCore is a coremod that reduces Minecraft's memory usage through multiple optimizations.github.com · 1 Oct 2026
Memory reduction: In the 1.16.4 Direwolf20 pack example, memory after garbage collection fell from roughly 3.1 GB to 1.1–1.2 GB on the title screen.curseforge.com · 1 Oct 2026
Fabric benchmark: In All Of Fabric 3 version 2.5.9, heap usage fell from 1,792 MB to 984 MB after generating a world and waiting two minutes.curseforge.com · 1 Oct 2026
Block-state savings: Replacing vanilla block-state neighbor tables with FastMaps is documented as saving around 600 MB in the cited test.github.com · 1 Oct 2026
Model savings: Caching multipart model predicates is documented as saving 300–400 MB in the cited test.github.com · 1 Oct 2026
Runtime behavior: Several documented optimizations have zero CPU impact while playing, with some load-time CPU cost.github.com · 1 Oct 2026
Supported loaders: The project is listed for Fabric, Forge, NeoForge, and Quilt.modrinth.com · 1 Oct 2026
Supported environments: The project is marked as supporting both client-side and server-side environments.modrinth.com · 1 Oct 2026
