ImmediatelyFast

by RaphiMC

ImmediatelyFast speeds up the client's immediate mode rendering of entities, particles, text, maps and the HUD.

What it does

Immediate mode rendering covers many small draw calls the game makes every frame: entities, block entities, particles, text, maps and the HUD. ImmediatelyFast replaces these paths with more efficient implementations and also changes some vanilla rendering code in targeted places. The same optimizations apply to immediate mode rendering done by other mods.

According to the author, gains appear when the processor is the bottleneck, so slower CPUs benefit more. ImmediatelyFast is client-side only, open source under the GNU Lesser General Public License v3.0 or later. Builds exist for Fabric, Forge, NeoForge and Quilt across 30 release versions, covering 1.18.2 – 26.3.

Key features

  1. Entity and particle rendering

    Entities, block entities and particles go through faster immediate mode rendering paths.

  2. Text, map and HUD

    Text, map and HUD drawing are reworked as well, which matters on screens with many labels or maps.

  3. Other mods included

    Immediate mode rendering performed by other mods benefits from the same changes.

  4. Four loaders

    Fabric, Forge, NeoForge and Quilt builds share the version 1.6.15 for 1.21.1, dated 2026-10-13.
