NumFlux
Mod that speeds up overall math of game. Compatible with other server-related performance mods.
Quick answer
Which NumFlux release matches 1.21.6 Quilt?
NumFlux 1.0.1-1.20.5-1.21.8-fabric targets 1.20.5, 1.20.6, 1.21 with Fabric, Quilt. Do not install it on the client. It must be installed on the dedicated server. 1 required mod needs a matching file.
Where it goes
Is NumFlux required on the client, server, or both?
Do not install it on the client. It must be installed on the dedicated server.
This file is marked server-only.
What else does NumFlux 1.0.1-1.20.5-1.21.8-fabric need?
1.0.1-1.20.5-1.21.8-fabric on 1.21.6 Quilt. Every mod below is checked against that same setup.
Install Architectury API first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
