Pack setup

How should I set up Mainly Optimized - Fps modpack for players and a server?

Client instance Install Mainly Optimized 1.12.2
Dedicated server setup Match Mainly Optimized 1.12.2
Pack loader Forge 14.23.5.2860

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Referenced mods 11
Client only 3
Server only 0
Not labelled 8

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Mainly Optimized - Fps modpack?

Mainly Optimized 1.12.2. Change the pack release and its contents or setup may change too.

11 mods in this pack file

The selected pack release is Mainly Optimized 1.12.2. That file is for Minecraft 1.12.2 with Forge 14.23.5.2860. It contains 11 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
