FjordMech

Minecraft 1.21.1 · NeoForge 21.1.265

• Add ServerCore 1.5.19 with its default settings.
• Set fresh-install guidance to simulation-distance=5 and view-distance=8 to limit active ticking and chunk delivery. These are starting values; keep existing server distances when upgrading.
• Enable server flight so players using FjordMech’s flight features aren’t kicked by vanilla flight checks.
• Disable Create Nuclear item radiation to avoid its per-item radiation scans and effects. The provided Spark analysis identified those scans as contributing to tick load.
• Disable Naturalist bugs and birds to reduce high-frequency mob activity.
