ZeroLag


ZeroLag is a cutting-edge optimization pack built for Fabric that extracts every drop of performance out of your game while maintaining a clean, highly functional Vanilla+ feel.

🚀 Key Features

💻 Ultimate Performance & Engine Fixes

We feature the industry standards for performance alongside advanced modern fixes to ensure stutter-free gameplay:

  • Rendering & Logic: Powered by Sodium, Sodium Extra, and ImmediatelyFast to completely overhaul modern frame delivery.
  • Memory & Optimization: Built-in ModernFix, FerriteCore, and BadOptimizations to aggressively handle native memory overhead and prevent allocation leaks.
  • Culling Tweaks: Entity Culling and More Culling stop your computer from wasting resources rendering hidden objects, blocks, and leaves.
  • Engine Enhancements: Includes Lithium for physics updates, C2ME (Concurrent Chunk Management Engine) for threaded world loading, and Noisium for fast world generation math.
  • Bug Fixes: Debugify eliminates dozens of lingering vanilla bugs, while Alternate Current re-engineers redstone processing logic.

🛠️ Vanilla+ Quality of Life & UI Updates

Performance means nothing if the game isn't comfortable to play. ZeroLag includes clean UI additions:

  • Navigation & Mapping: Outfitted with Xaero's Minimap and Xaero's World Map for seamless exploration.
  • Inventory & UI: Enhanced item management via Mouse Tweaks, better stat tracking with Better Statistics Screen, and a cleaner Better Advancements window.
  • Visual Enhancements: Clean dark backgrounds using the Unique Dark / GUI PurpleOLED style (which can be easily removed or turned off by going into your Resource Packs settings), custom GUI styling with OptiGUI, and specialized visual tweaks like Dynamic Crosshair and Enchantment Glint Outline.
  • Cactus Mod Client: Access utility features by pressing Right Shift (RShift); to learn more about its capabilities, visit their official page here.
  • Privacy & Safety: Ships with No Chat Reports to ensure your multiplayer text remain private and secure.

Frequently Asked Questions

ZeroLag server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a ZeroLag server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).

Can I add custom mods to ZeroLag without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.1.2). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

ZeroLag server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
