OptiCraft Description

OptiCraft is a client-side Fabric performance mod focused on improving FPS stability, lowering stutter, and reducing unnecessary CPU/memory overhead in common gameplay scenarios.

It uses a modular optimization system so each performance feature can be toggled independently. You can run it in safe mode, tune individual modules, or enable aggressive presets for higher performance.

Core Focus Areas

• Rendering: skips duplicate chunk rebuild scheduling where safe.
• Client Tick: reduces repeated allocations in hot per-tick logic.
• Entity Handling: caches repeated client entity lookups to reduce redundant work.
• Memory: canonicalizes repeated Identifier objects with an LRU cache.
• IO: uses async handling for non-critical tasks (like debounced config saves/resource sampling).
• Networking: reduces packet-path allocations with identifier canonicalization.

Advanced Modes

• Compatibility Mode: disables high/extreme risk patches for maximum mod compatibility.
• Maximum Performance Mode: enables and tunes all major optimizations automatically.
• Ultra Aggressive Mode: pushes cache and dedupe settings further.
• Unsafe Extreme Mode: enables invasive FPS-first patches (particle budget limiting and short-window sound dedupe).

Configuration + UX

• Full in-game config UI via Cloth Config (when installed).
• Mod Menu integration for one-click config access.
• Fallback config screen if Cloth Config is missing.
• Built-in debug overlay with module state + optimization counters.

Compatibility

• Fabric client mod.
• Java 17+.
• Universal best-effort jar targeting Minecraft 1.20.1+ with runtime-gated mixins.
