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. Whether you are running on a high-end rig or a low-spec laptop, this pack stabilizes your frame rates, fixes underlying engine bugs, and modernizes your interface.
🚀 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.
📦 Manual Recommendation Note
To comply with platform restrictions, a few highly recommended client-side optimizations are hosted under restrictive licenses. For the absolute best stability against VRAM issues, we highly recommend manually downloading:
- fix GPU memory leak from CurseForge and dropping it straight into your local
mods/folder!
⚙️ Configuration & Keybinds
ZeroLag ships pre-configured with streamlined video options. To adjust individual settings, open your settings menu inside Mod Menu, powered behind the scenes by YetAnotherConfigLib and Cloth Config API.
