? Why Fabric?

Fabric was chosen because it:

• Is lightweight
• Loads faster than Forge/NeoForge
• Has lower overhead
• Provides the best optimization ecosystem (Sodium + Lithium + FerriteCore stack)

This ensures maximum compatibility and minimum performance impact.

? Recommended Settings

For best performance:

• Use 6–8GB RAM maximum (more is not always better)
• Enable VSync OFF
• Use fullscreen mode
• Reduce simulation distance if CPU bound
• Let Sodium handle advanced rendering settings

? Server Compatibility

OptiMin is fully compatible with:

• Vanilla servers
• Fabric servers
• Most NeoForge/Forge servers (client-side mods only)

ServerCore improves performance when installed server-side.

? Installation

1. Install .mrpack or .zip
2. Launch the game

? Issues & Support

If you encounter crashes:

• Check the Crash Assistant report
• Verify mod version compatibility
• Avoid adding unknown optimization mods that conflict with Sodium
