Exordium vs FerriteCore

Exordium is a free, client-side Minecraft mod that renders selected vanilla interface elements at a configurable fixed frame rate. Lowering the interface rendering rate is intended to free CPU and GPU time for world rendering. Affected elements include overlays, the hotbar, crosshair, bossbars, the debug screen, titles, scoreboard, and chat. It is listed for Minecraft 1.19.4 and later on Linux, macOS, and Windows, with Fabric, NeoForge, Forge, and Quilt support. The project links to CurseForge and Modrinth for downloads, and does not require Sodium or support dedicated servers. The repository lists compatibility with several mods, including Sodium, Iris, Optifine, AppleSkin, JourneyMap, and BetterF3; VulkanMod is listed as incompatible. Only the vanilla GUI is supported, so mod-rendered interface elements may not work. Screen-setting support remains unfinished, is disabled by default, and can have transparency issues. The project is in maintenance mode, with no new features or fixes planned for bugs involving other mods.

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.
