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 ## 📜 License This modpack includes mods developed by their respective authors.
