Instead of ImmediatelyFast

ImmediatelyFast alternatives

ImmediatelyFast is a free, open-source Minecraft: Java Edition client mod for Linux, macOS, and Windows. It targets immediate-mode rendering, batching draw calls and sending data to the GPU efficiently. Its optimizations cover entities, block entities, particles, text, GUI and HUD elements, maps, and rendering from other mods. Fabric, Forge, NeoForge, and Quilt loaders are supported across many Minecraft versions. A configuration file lets you adjust performance or compatibility settings, and the project is designed to remain lightweight alongside most mods and modpacks.

Switching makes sense when your needs extend beyond rendering. Improvements depend on a CPU bottleneck, with slower processors benefiting more, while OptiFabric, OptiFine, LunarClient, and LabyMod are incompatible. ImmediatelyFast is client-only, lacks dedicated-server support, and does not target memory, networking, redstone calculations, GUI frame pacing, or alternate rendering engines. Weigh each option’s optimization scope, loader and platform support, hardware requirements, client/server reach, and compatibility before replacing ImmediatelyFast or adding another mod alongside it.
