Pack setup
How should I set up OptiSup [Client] for players and a server?

Dedicated server setup Match 3_26.1.2_neoforge
Pack loader NeoForge 26.1.2.100
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 23
Client only 9
Server only 0
Not labelled 14
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 OptiSup [Client]?
3_26.1.2_neoforge on 26.1.2. The pack contents and setup notes below stay tied to that release.
The selected pack release is 3_26.1.2_neoforge. That file is for Minecraft 26.1.2 with NeoForge 26.1.2.100. It contains 23 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.
