Rubidium Mod Performance Settings Guide

Rubidium is a Forge-focused rendering optimization mod. The safest setup approach is to match every component to the same Minecraft version and make changes in a controlled order.

Key steps

Start with moderate render distance and simulation distance.
Disable heavy shaders while measuring baseline performance.
Reduce expensive visual options before lowering resolution.
Change one group of settings at a time so the effect is measurable.

Compatibility checks

Before launching, verify Minecraft, Forge or NeoForge where applicable, Rubidium and any shader or rendering add-ons. The Rubidium project explicitly states that OptiFine is not compatible.

Practical test method

Launch a clean profile first. If it works, add resource packs, shaders and other mods in small groups. This makes it much easier to identify the component that introduces a crash or visual problem.
