Pack setup

How should I set up Simple Performance optimizer for players and a server?

Use optimization 1.20.1-1.0.0 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Pack loader Forge 47.4.10

24 mods in this pack file

The selected pack release is optimization 1.20.1-1.0.0. That file is for Minecraft 1.20.1 with Forge 47.4.10. It contains 24 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

About this project

What kind of pack is Simple Performance optimizer?

🚀 Intel UHD & Low RAM Extreme Optimizer forge/fabric

An ultra-lightweight, high-performance optimization modpack built specifically for low-end PCs, school laptops (like ASUS Vivobook), and integrated graphics (Intel UHD / Iris Xe). Fully tested, fine-tuned, and proven to deliver an astonishing **400+ FPS in the air** and **120+ stable FPS in dense forests** using only 6 GB of RAM allocation!

Unlike other performance packs that cause graphical glitches or flashing screens, this pack focuses on **pure stability and smoothness**. Every single mod has been carefully selected to eliminate background stuttering and chunk-loading bugs completely.


📸 PERFORMANCE PROOF (400+FPS!)

Check the **Images / Screenshots** tab to see the official proof! The modpack achieves **505 FPS** running on a standard Intel UHD graphics card with only 6 GB of total system RAM. No tricks, just pure, extreme optimization.


✨ Key Features & Enhancements:

* **Next-Gen Graphical Render:** Powered by Embeddium and ImmediatelyFast to completely replace OptiFine, offering massive FPS gains and smooth menus.
* **Smart CPU Distribution:** Thread Tweaks and Radium Reforged optimize mob AI, physics, and world logic, spreading the workload perfectly across your processor cores.
* **Extreme Memory Protection:** ModernFix, FerriteCore, and Smooth Boot (Reloaded) slash RAM consumption in half, preventing "Not Responding" freezes when launching the game.
* **Flawless Chunk Loading:** Features advanced background optimizations (Noisium & Chunk Sending) to load terrain smoothly, keeping your game lag-free (85+ FPS) even when moving at high speeds!


⚙️ MANDATORY LAUNCHER SETUP (For 6 GB RAM Systems):

To prevent "Out of Memory" crashes and ensure your Intel UHD card functions at maximum efficiency, you **MUST** paste these exact JVM Arguments into your launcher settings:

-Xmx3G -Xms3G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=20 -XX:+UnlockExperimentalVMOptions -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1ReservePercent=20 -XX:G1HeapRegionSize=8m -XX:G1TargetsToGrid=true


💡 Recommended In-Game Settings for Maximum FPS:

  1. **Render Distance:** Set manually between **9 and 11 Chunks** (the sweet spot for 120+ FPS).
  2. **Simulation Distance:** Set to **5 or 6 Chunks**.
  3. **Mipmap Levels:** Turn **OFF (0)** to instantly free up VRAM on your integrated graphics.
  4. **Clouds:** Turn **OFF** or set to **Fast**.
  5. **Background Apps:** Close Google Chrome, Discord, or Spotify before clicking Play to save your precious RAM!
