Quick answer
Which OptiSup [Client] release matches Forge?
Best match for your filters 2_1.20.1_forge
Game version 1.20.1
Loader Forge 47.4.23
2_1.20.1_forge is a complete pack release for 1.20.1 with Forge 47.4.23. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 24 mods in this pack file.
Pack setup
How should I set up OptiSup [Client] for players and a server?
Use 2_1.20.1_forge as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
Client instance Install 2_1.20.1_forge
Dedicated server setup Match 2_1.20.1_forge
Pack loader Forge 47.4.23
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 24
Client only 8
Server only 0
Not labelled 16
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]?
2_1.20.1_forge on Forge. The pack contents and setup notes below stay tied to that release.
The selected pack release is 2_1.20.1_forge. That file is for Minecraft 1.20.1 with Forge 47.4.23. It contains 24 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.
