Mod Optimization
- Limit Mods: Use only essential mods (10-15 max)
- Avoid Conflicts: Test mod compatibility before deployment
- Update Regularly: Keep mods updated to latest versions
- Monitor RAM: Large mods like Calamity need 4GB+ RAM
Important: Terraria is single-threaded. High single-core CPU speed is more important than core count for performance.
