Optium
all the functions of Optifine for fabric in one modpack
Quick answer
Which Optium release should I use?
Optium RC 0.7.6 is a complete pack release for 1.19.4 with Fabric 0.15.6. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 34 mods in this pack file.
Pack setup
How should I set up Optium for players and a server?
Use Optium RC 0.7.6 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.
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.
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 Optium?
Optium RC 0.7.6. Change the pack release and its contents or setup may change too.
The selected pack release is Optium RC 0.7.6. That file is for Minecraft 1.19.4 with Fabric 0.15.6. It contains 34 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.

Not required reading
I'll say in advance that there probably won't be a modpack for two versions 1.16.5 and 1.17.1 because there is a mod for Fresh animations starting from 1.18.2 I'll probably make a modpack for 1.16.5 and 1.17.1, but without Fresh animations support, definitely do not add to the MemoryLeakFix modpack minecraft will not be able to start this description will be updated
