ImmediatelyFast review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

ImmediatelyFast is an open-source Minecraft mod for improving client-side immediate-mode rendering performance. It is aimed at players who want broad rendering optimization across common in-game elements rather than a tool focused on one visual subsystem. The mod batches immediate-mode draw calls and uploads data to the GPU more efficiently, while covering entities, block entities, particles, text, maps, GUI elements, and HUD elements. Its documented scope is client-only, and current project metadata lists Fabric and NeoForge builds for Minecraft 26.3.

Its main strength is breadth. Instead of concentrating only on entity rendering or only on interface elements, ImmediatelyFast applies configurable rendering optimizations across several categories. That makes it a practical fit for users looking for one mod with a wide client-side rendering focus. The project is also designed to remain lightweight and compatible with other mods, which supports a broader modded setup. Fabric and NeoForge support gives it multi-loader coverage within the documented Minecraft version.

ImmediatelyFast is not a dedicated-server performance mod, and its focus is rendering rather than general server optimization. It should suit players seeking configurable client-side improvements across entities, particles, text, maps, and interface rendering. Users looking specifically for server-side performance changes, or for functionality outside rendering, should choose a different type of mod. Its open-source model and client-only deployment keep the product scope clear: it is a focused rendering component for the Minecraft client, not a complete performance suite.
