Optimized Rendering Categories

ImmediatelyFast improves performance by optimizing how the game handles immediate mode rendering—a traditional rendering approach where objects are drawn directly to the screen without being batched or stored. It also directly rewrites parts of the vanilla rendering system for extra speed.

Immediate Mode Optimizations

These optimizations focus on systems that use immediate rendering in the game or via other mods:

Entity Rendering

All in-game creatures, mobs, and players are considered entities. ImmediatelyFast batches their draw calls efficiently, reducing redundant processing and improving rendering speed, especially in crowded scenes like mob farms or villages.

Block Entity Rendering

Block entities (like chests, furnaces, beacons, etc.) often have dynamic visuals. The mod optimizes how these are drawn by grouping similar render operations together, reducing overhead and improving frame consistency.

Particle Rendering

Particle effects (like smoke, explosions, fire, and redstone dust) can cause heavy performance drops when numerous. ImmediatelyFast speeds up their rendering by reducing how often data is pushed to the GPU and improving memory management.

GUI and HUD Rendering

Graphical interfaces (like inventory screens) and heads-up display elements (like health, hunger, and armor bars) are redrawn constantly. This mod improves how these elements are rendered, reducing frame delay and improving responsiveness.

Text Rendering

In Minecraft, text appears everywhere—from signs and name tags to menus. ImmediatelyFast optimizes font rendering by minimizing redundant texture uploads and drawing text more efficiently, especially useful when dealing with long strings or chat logs.

Compatibility with Other Mods’ Immediate Mode Rendering

Many mods use immediate mode to render custom objects or GUIs. ImmediatelyFast automatically enhances these render paths as well, without requiring mod authors to make changes. This ensures wide mod compatibility and consistent performance gains.

Targeted Vanilla Rendering Optimizations

In addition to general immediate mode improvements, ImmediatelyFast directly rewrites and optimizes some specific vanilla rendering systems for higher efficiency:

Map Rendering

Vanilla map rendering can be surprisingly resource-intensive due to the constant updates and color blending. ImmediatelyFast rewrites parts of this to reduce CPU overhead and improve map responsiveness.

HUD Rendering Improvements

Even the standard HUD (health, crosshair, status bars) can cause slowdowns due to how often it’s refreshed. The mod restructures this rendering path to reduce unnecessary draw calls and make it more GPU-efficient.

Enhanced Text Rendering System

Minecraft’s vanilla text system wasn’t designed for performance. ImmediatelyFast enhances it by caching, reusing glyphs, and reducing calls to the text renderer. This not only speeds up in-game text but also improves overall GUI responsiveness.

Performance Benefits

ImmediatelyFast delivers significant performance improvements by optimizing how rendering is handled in Minecraft. Here’s what that means in detail:

Reduced Frame Time Spikes

Frame time spikes are sudden delays between frames that cause stuttering or lag, even when your FPS seems high.
ImmediatelyFast minimizes these spikes by batching draw calls more efficiently and reducing the overhead of rendering each frame—making gameplay feel consistently smooth, especially during intense scenes like combat or large world loads.

Better Frame Rates in High-Entity Scenes

In areas with lots of entities (e.g., mobs, item drops, or complex farms), Minecraft’s rendering engine can struggle.
ImmediatelyFast optimizes how entities and block entities are rendered, resulting in noticeably higher FPS and improved responsiveness in such demanding environments.

Smoother UI Transitions

Menus, HUDs, chat windows, and other GUI elements are also rendered more efficiently.
This means smoother opening/closing of inventories, less lag when switching screens, and better responsiveness in modded interfaces—especially helpful in heavy modpacks with complex UIs.

Lower Resource Usage on Mid to Low-End Systems

Older or less powerful PCs often suffer from performance drops due to inefficient rendering.
By streamlining how rendering works at a low level, ImmediatelyFast reduces CPU and GPU load, allowing budget systems to run smoother, cooler, and with fewer slowdowns—making modded Minecraft more accessible to everyone.

Installation Instructions for ImmediatelyFast

How to Install

Download and install a mod manager:

  • Open the app and select your Minecraft profile (Fabric or Quilt).
  • Use the search bar to find ImmediatelyFast.
  • Click Install, and it will handle the dependencies automatically.
  • Launch the game and enjoy improved rendering!

Manual Installation

Install Fabric or Quilt loader

  • Go to immediatelyfast.com and download the Fabric installer.
  • Run the installer and select the correct Minecraft version.

Locate your Minecraft mods folder:

  • Windows: C:\Users\<YourName>\AppData\Roaming\.minecraft\mods
  • macOS: ~/Library/Application Support/minecraft/mods
  • Linux: ~/.minecraft/mods

Configuration (if any)

  • ImmediatelyFast is designed to work out of the box with no configuration required for most users.
  • Advanced Users: If available, configuration files can typically be found in the config/ folder inside .minecraft.
  • The mod may expose options via ModMenu if you have it installed, allowing simple toggles for certain optimizations.

Use Cases & Scenarios

Ideal for Modpacks with Many UI Mods

Modpacks that include multiple UI-enhancing mods (like REI, Inventory HUD+, or AppleSkin) can place a heavy load on the rendering system, especially when every UI element uses immediate mode rendering.
ImmediatelyFast optimizes how these UI elements are drawn, reducing redundant GPU calls and smoothing out the interface. This leads to:

  • Faster screen transitions
  • Lower UI-related lag
  • Better overall experience in inventory-heavy modpacks

Great for Builders Using High-Entity Maps

In large creative builds, players often spawn hundreds or thousands of entities and block entities — from item frames and armor stands to redstone contraptions and decorative blocks.
Without optimization, rendering all of these can cause serious FPS drops.

ImmediatelyFast significantly improves performance in such environments by:

  • Batching draw calls for entities and block entities
  • Reducing the overhead of dynamic object rendering
  • Keeping frame rates more stable in complex scenes

Helps with Streamlining Performance in Heavily Modded Environments

When you’re running large modpacks with 100+ mods, rendering performance becomes a bottleneck — especially when many mods use immediate mode drawing for HUDs, particles, GUIs, and custom renderers.

ImmediatelyFast streamlines this by:

  • Acting as a drop-in optimization layer for any mod that uses vanilla immediate mode rendering
  • Ensuring consistent performance regardless of how many mods draw to the screen
  • Preventing cumulative lag caused by unoptimized rendering logic

This makes it a must-have performance mod for players who love big, complex, content-heavy modpacks.
