Embeddium vs ImmediatelyFast

Embeddium is a free Minecraft mod focused on rendering performance on the game client. It uses a multi-loader setup and is listed for Minecraft 1.16.5, 1.18.2, 1.19.2, versions 1.20.1 through 1.20.6, versions 1.21 through 1.21.1, and version 1.21.4. The mod does not require Sodium. Its stated scope is client-side use, so it is intended to run with the player’s Minecraft installation rather than as dedicated server software. Dedicated server support is not provided. Embeddium is available through Modrinth with a free plan. The main selection check is version matching: users need one of the listed Minecraft releases. The multi-loader designation indicates that it supports more than one mod-loading environment. Because its focus is rendering, it is aimed at installations where client rendering performance is the relevant need. Server operators should distinguish that client scope from dedicated-server requirements when deciding whether it fits their setup.

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.
