Description
What is xOptimizePack?
xOptimizePack is a lightweight Fabric optimization pack focused purely on performance - higher FPS, less stutter, and lower memory usage on low-end and mid-range PCs. No visual changes, no shaders, no fluff - just raw performance gains.
Benchmark Results
| Clean Minecraft | xOptimizePack | |
|---|---|---|
| 0.1% Lows | 45.3 FPS | 141.2 FPS |
| Max FPS | 924.4 FPS | 4075 FPS |
That's roughly 3x better 1% lows and 4x higher max FPS - meaning smoother gameplay with far fewer stutters, not just a higher number on the counter.
Key Features
- Massive FPS increase through optimized rendering, chunk loading, and entity processing
- Lower RAM usage and fewer freezes caused by garbage collection
- Reduced stutter and microlag during gameplay and world generation
- Optional Vulkan renderer (VulkanMod) for an extra FPS boost on supported GPUs
- Zero visual changes - looks exactly like vanilla Minecraft
- Lightweight - 9 mods total, minimal overhead
⚠️ Compatibility Note
This pack uses VulkanMod, which replaces the default rendering engine. It is NOT compatible with shaders (Iris/Sodium shader packs). If you want to use shaders, simply disable VulkanMod in the mods list - the rest of the pack works fine without it.
Included Mods
| Mod | What it does |
|---|---|
| Fabric API | Core library required by other mods |
| Lithium | Optimizes game logic and server-side performance |
| FerriteCore | Reduces memory usage, especially with many mods |
| EntityCulling | Stops rendering entities you can't see, improving FPS |
| ModernFix | Fixes performance bugs, reduces RAM use and load times |
| SuperFastMath | Speeds up internal math calculations used by the game |
| VulkanMod | Replaces OpenGL with Vulkan for better FPS (disables shader support) |
| Placeholder API | Required dependency for mod compatibility |
| Mod Menu | In-game menu to view and configure installed mods |
Who is this for?
Anyone running Minecraft on a weaker PC, or anyone who wants more FPS and less stutter without needing shaders or visual mods. If you do want shaders, just disable VulkanMod and keep the rest of the pack.
