Oxygen

Oxygen is a performance-focused Fabric mod for Minecraft . It boosts FPS and reduces rendering workload by intelligently culling entities, block entities, and effects that are outside the view or hidden behind blocks, while also adding memory optimizations and useful client-side options.

• Smart entity and block-entity culling (occlusion + frustum)
• Density-based rendering for crowded areas (forests, bamboo, item piles)
• Tick culling to reduce CPU load on distant entities
• Optional entity shadow optimizations
• Memory optimizations for model/baked quad sharing and caches
• Visual tweaks: cloud/sign/weather/beacon culling
• Item frame and painting culling with LOD controls
• Optional camera zoom and debug overlays

All options are configurable via:

• In-game video settings additions

• Built for client-side performance improvements.
• Safe to install on existing worlds.
• No shaders support for now.
