Description

# 🚀 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!
