❄️ IceOptimizer — Break the Ice, Boost the FPS

IceOptimizer is a lightweight, performance-focused modpack designed to turn your "potato PC" into a smooth gaming machine. Built on the cutting-edge Fabric loader, this pack focuses purely on optimization, client-side fixes, and essential quality-of-life features without changing the core vanilla gameplay.
🚀 Key Optimization Features
- The Power Trio: Powered by Sodium, Lithium, and FerriteCore to completely overhaul rendering, logic, and memory usage.
- Smart Culling: Uses EntityCulling, More Culling, and BadOptimizations to stop rendering things you can't see, saving massive CPU and GPU resources.
- Seamless Generation: Integrated with C2ME (Concurrent Chunk Management Engine) and Noisium to eliminate chunk-loading stutters during exploration.
- Memory Efficiency: Thanks to ModernFix and ThreadTweak, the pack runs beautifully even with only 2GB–4GB of allocated RAM.
- Network Optimization: Uses PacketFixer to reduce ping and stabilize connections on multiplayer servers.
🛠 Enhanced Capabilities & QoL
- OptiFine Features: Full support for shaders (Iris Shaders), zoom (Zoomify), and optimized resource pack loading (Language Reload, Animatica, EBE).
- Bug Fixes: Eliminates over 100+ vanilla bugs out-of-the-box using Debugify and Not Enough Crashes.
- Effortless Multiplayer: Includes e4mc, allowing you to open your singleplayer world to friends without setting up complex port forwarding or hosting servers.
📥 Quick Installation
- Go to the Versions tab and download the latest
.mrpackfile. - Import the file into the Modrinth App or Prism Launcher.
