Arbitrium

The official client modpack for Taxphobia Vanilla Season 11.

Arbitrium is built for one thing: getting out of your way. No visual overhauls, no gameplay changes just a heavily optimized client that makes Minecraft run the way it should have from the start. Faster load times, higher frame rates, smoother chunk rendering, and a handful of essential quality-of-life fixes that every player needs without even knowing it.

If you're joining the server, this is your baseline.
