MC Xtended

MC Xtended is a Fabric modpack that preserves the vanilla Minecraft experience, while improving performance, fixing many bugs, and adding quality of life features.

It’s aimed at players who want a modernized vanilla experience — featuring better performance, smoother rendering, fewer stutters, and small UX improvements, all while maintaining the vanilla charm.

Highlights:

• Performance first: modern Fabric optimizations for both client and server.
• Vanilla parity: bugfixes and QoL that do not alter core mechanics.
• One‑click server creation: open your singleplayer world to friends with one click using e4mc — it makes your LAN world public so friends can join easily. It also supports offline mode: disable online mode when opening to LAN if you need to play without online authentication.
• Cosmetics: get a cape at MinecraftCapes and show it in‑game using the included cape support mod.
• Optional server package: download a ready‑to‑use MCXtended_Server.zip containing a fabric server.jar, an optimized start.sh, and all server‑side mods for quick deployment. Download it from GitHub.

• Core optimizations spotlight:
  • Sodium — massive FPS gains through rendering optimizations.
  • Lithium — faster tick calculations and mob AI improvements.
  • FerriteCore — reduced memory usage for chunk and block data.
  • ImmediatelyFast — snappier responsiveness and reduced stutter.
  • ThreadTweak — smarter JVM thread scheduling for smoother gameplay.
  • ScalableLux — optimized light engine for better performance.
  • ServerCore — server‑side toolkit for lag reduction, entity controls, and chunk ticking optimizations.
• Smarter resource use: mods like Clumps, Dynamic FPS, and Entity Culling reduce idle resource usage, merge XP orbs, and skip rendering hidden entities — keeping gameplay smooth even on lower‑end systems.
• Improved network stack: Krypton optimizes server networking for lower latency and smoother multiplayer performance.
• Beginner‑friendly tools: mods like Jade, Xaero’s Minimap & World Map, REI, and Enchantment Descriptions make the game easier to learn by showing block info, guiding exploration, simplifying recipes, and explaining enchantments — perfect for new or inexperienced players.
• Bugfixes included: long‑standing vanilla issues are patched with mods like Debugify and ModernFix, ensuring smoother gameplay.
• Flexible visuals: built‑in shader support with Iris and curated packs like Complementary Reimagined or Vanilla Plus Shader let you enhance graphics without breaking vanilla style.
• Lightweight customization: UI polish from BetterF3, Raised, Reese’s Sodium Options, and Better Ping Display makes menus cleaner and more informative without overwhelming players.
