Performance Mods
Lumo Optimized includes the most effective performance mods available for Fabric. These mods work together to dramatically improve FPS, reduce memory usage, and speed up loading times.
Core Optimization
Section titled “Core Optimization”Sodium
Section titled “Sodium”The foundation of Minecraft performance optimization.
Sodium completely rewrites Minecraft’s rendering engine, providing massive FPS improvements on most hardware. It’s the most impactful performance mod you can install.
Benefits:
- 3-5x FPS improvement on average
- Better chunk loading
- More efficient memory usage
- Reduced CPU overhead
Settings: Options → Video Settings
Lithium
Section titled “Lithium”Game logic and server optimization.
Lithium optimizes many game systems including mob AI, world generation, physics calculations, and more. Unlike Sodium, Lithium works invisibly in the background.
Benefits:
- Faster world generation
- Reduced tick times
- Better mob performance
- Lower CPU usage
Settings: No configuration needed - it just works!
FerriteCore
Section titled “FerriteCore”Memory usage optimization.
FerriteCore reduces Minecraft’s memory footprint, allowing more RAM for other things like higher render distances or more mods.
Benefits:
- 40-50% reduction in memory usage
- Fewer out-of-memory crashes
- Better performance with many mods
- Allows more RAM for other uses
Settings: No configuration needed.
Rendering Optimization
Section titled “Rendering Optimization”ImmediatelyFast
Section titled “ImmediatelyFast”Immediate mode rendering optimization.
Optimizes various rendering systems that Sodium doesn’t cover, like HUDs, text rendering, and map rendering.
Benefits:
- Faster text rendering
- Smoother HUD updates
- Better map performance
- Reduced frame time spikes
Entity Culling
Section titled “Entity Culling”Skip rendering entities you can’t see.
Entity Culling prevents Minecraft from rendering entities that are hidden behind blocks, saving significant GPU resources in crowded areas.
Benefits:
- Major FPS boost in villages and farms
- Reduced GPU load
- Smoother gameplay near many mobs
- Works with all entities
More Culling
Section titled “More Culling”Additional culling optimizations.
Extends culling to more game elements like block entities, particles, and other rendering that Entity Culling doesn’t cover.
Benefits:
- Culls item frames and paintings
- Optimizes particle rendering
- Reduces unnecessary draw calls
- Complements Entity Culling
Background Optimization
Section titled “Background Optimization”Dynamic FPS
Section titled “Dynamic FPS”Reduce resource usage when not playing.
When Minecraft is in the background or paused, Dynamic FPS dramatically reduces the frame rate to save power and system resources.
Benefits:
- Near-zero GPU usage when alt-tabbed
- Lower power consumption
- Reduces system heat
- Better laptop battery life
Settings: Mods → Dynamic FPS
| Setting | Recommended |
|---|---|
| Unfocused FPS | 1-5 FPS |
| Hidden FPS | 0 FPS |
| Pause when unfocused | Your preference |
Performance Tips
Section titled “Performance Tips”For Maximum FPS
Section titled “For Maximum FPS”- Keep shaders disabled
- Set render distance to 12-16 chunks
- Disable fancy graphics
- Use fast clouds or disable them
- Lower entity distance
For Balanced Performance
Section titled “For Balanced Performance”- Use shader performance presets
- Set render distance to 16-24 chunks
- Enable Voxy for far views (highly efficient)
- Keep default quality settings
Monitoring Performance
Section titled “Monitoring Performance”Use spark (included) to profile your game:
/spark profiler start/spark profiler stopPress F3 to see real-time FPS and performance metrics.
