Rhenium

Rhenium

Rhenium is a Fabric performance optimization mod designed to reduce lag in large survival worlds, particularly those with complex redstone contraptions and automated storage systems.

What it optimizes:

• Hopper throttling — Idle hoppers that have nothing to move are throttled, significantly reducing tick overhead in large storage systems with many hoppers
• Item entity throttling — Stationary ground items tick less frequently, reducing lag in areas with large item piles
• Chest render culling — Chest block entity renderers are skipped beyond 24 blocks, reducing client FPS drops in storage rooms with many chests
• Particle culling – Changes the distance at which the particles are rendered
• Entity culling – Changes the distance in which the entities are rendered

Fully configurable — Every optimization can be toggled individually via Mod Menu, so you keep only what you need.

Requirements:

• Fabric Loader 0.16.10+
• Minecraft 1.21.1 – 1.21.11, 26.2
• Mod Menu
• Cloth Config

Recomended mods:

• Sodium
• Lithium
• Entity culling
