FerriteCore vs More Culling

FerriteCore is a free, MIT-licensed coremod for Minecraft: Java Edition that targets RAM use. It reduces memory associated with block states, models, predicates, strings, voxel shapes and baked quads through a set of documented optimizations. Examples include replacing block-state neighbor tables with FastMaps, caching multipart model predicates, deduplicating model instances and reducing baked-quad memory. The project reports that individual techniques saved hundreds of megabytes in cited tests; one pack example showed post-garbage-collection memory moving from roughly 3.1 GB to 1.1–1.2 GB on the title screen. Several optimizations have no CPU impact during play, while some add load-time CPU cost. ThreadingDetector optimization is disabled by default because it may very rarely cause race conditions. FerriteCore supports Fabric, Forge, NeoForge and Quilt and is listed for Minecraft Java Edition versions 1.16.5 through 26.3, depending on loader builds. It is marked for both client and server use, and the maintainer recommends installing it on both because some optimizations apply server-side. Versions before 1.16 are not supported for backporting.

More Culling is a free Minecraft: Java Edition mod that changes how the game skips rendering objects the player cannot see. Its project wiki describes techniques for block states, item frames, leaves, and paintings, along with custom culling shapes and model shapes for resource packs. API guidance covers custom block culling and troubleshooting culling issues on modded blocks. The listed Minecraft versions are 1.18.x through 1.21.x and 26.1.x through 26.3. Fabric, NeoForge, and Quilt are listed as supported loaders. The project information lists client-side and client-and-server environments, while the supplied compatibility details specify client scope and no dedicated server support. More Culling requires Cloth Config. The related MoreCullingExtra extension adds culling combinations involving glass panes, glass, and beacons. The mod is licensed GPL-3.0-only. Its maintainer permits modpack use with attribution, but asks users to obtain permission before merging it into a client or another mod. The project directs bug reports to its issue tracker and also links to a Discord server.
