ImmediatelyFast vs More Culling

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.

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.
