Prehistoric World Server Hosting

Plan on 8 GB. The 266 mods alone make this a heavy Forge 1.20.1 pack, and the dinosaurs are large animated mobs with their own AI, which costs more memory and tick time than vanilla animals. If you add mods of your own or your group explores far in different directions, watch the usage graph and scale up when it climbs.

Around six players is the sweet spot on the recommended 8 GB. Every player who heads off alone loads a separate stretch of land full of creatures, so a group that spreads out costs more than one that travels together. Larger groups work too, but give the server extra RAM and pregenerate a wider area first.

Take a backup first, then install the new build from the Modpacks tab and update every client to the same version. Builds of this pack arrive often, and one that removes a mod can leave its dinosaurs or blocks missing from your world. Start the server once, read the console for errors and roll back to the backup if anything is gone.

Yes, but treat the pack as a set. Any mod you add must target Forge 1.20.1 and be installed on the server and on every client. Removing a mod that adds creatures or blocks wipes them from existing chunks, so test the change on a copy of the world first, and note your edits so you can reapply them after a pack update.

Both run on Forge 1.20.1, but they pull in opposite directions. All the Mods 9 is a kitchen-sink pack centred on tech, magic and automation, while Prehistoric World focuses its 266 mods on dinosaurs, survival and quest-led adventure. Pick Prehistoric World if your group wants an expedition among prehistoric creatures rather than a race to build factories.

Each dinosaur runs its own AI and animations every tick, so a herd costs far more than the same number of cows or sheep. Lag that only shows up near large groups points to entity load. Run a spark profile while standing close to them to confirm it, and avoid penning a huge herd right next to your base.
