Exordium vs ImmediatelyFast

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.

ImmediatelyFast is a free, open source Minecraft mod that improves client-side rendering performance in Minecraft: Java Edition. It batches draw calls using a custom buffer and sends data to the GPU more efficiently. Its optimizations cover entities, block entities, particles, text, GUI and HUD, maps, and immediate mode rendering used by other mods. The project supports Fabric, Forge, NeoForge, and Quilt, with compatibility listed for Minecraft versions 1.18.2 through 1.21.x and versions 26.1.x, 26.2, and 26.3. It is designed to work with most mods and modpacks, but names OptiFabric, OptiFine, LunarClient, and LabyMod as incompatibilities. The project says it can improve FPS when the CPU is the bottleneck, with slower CPUs benefiting more than very fast ones. A configuration file in the Minecraft instance’s config folder offers performance or compatibility options. The mod is licensed under LGPL-3.0-or-later, and developers can consult API documentation. The project links to a GitHub issue tracker and Discord server for support.
