🔮 G1ax Crystal Optimizer
The ultimate, high-performance crystal PvP optimization mod for Minecraft 1.21.1+ (Fabric)
G1ax Crystal Optimizer is a advanced, highly optimized Fabric client mod that improves crystal PvP mechanics with intelligent packet management, dynamic latency adaptation, and client-side enhancements. It comes equipped with safety controls for competitive servers and a diagnostic system to ensure compatibility with other mods.
⚡ Key Modes
Use the command /g1axoptimizer <default|tweak|off> to configure the mod on the fly:
🛡️ /g1axoptimizer tweak — AC-Safe Mode
Designed specifically for servers with strict anticheat constraints (e.g. anti-cheat plugin detection):
- Bypasses Placement Cooldown: Resets Minecraft's hardcoded 4-tick (200ms)
itemUseCooldownto check placement conditions every tick (~50ms). - 100% Vanilla Logic: Does not inject custom packets, perform predictive visual removal, or bypass vanilla validation logic. Your placement attempts remain completely vanilla.
🚀 /g1axoptimizer default — Full Mode
Maximum PvP performance for environments where optimizer clients are allowed:
- Intelligent Packet Optimization: Dynamically adjusts placement packet injection (1 packet for <50ms ping, 2 packets for >50ms ping).
- Client-Side Visual Removal: Instantly removes broken crystals visually, providing zero-delay feedback without waiting for server response packets.
- Direct Block Interaction: Bypasses slow default block verification sequences for faster crystal placing.
- Async Execution: Performs math and validation in parallel threads, keeping client frame rates fluid and lag-free.
🔧 Pre-Flight Diagnostics & Logger
Never worry about crashes or incompatible mods:
- Pre-Flight Checker (
CompatibilityChecker): Checks Minecraft Version, Fabric API status, Mixin targets, and Java 21+ configuration on launch. Warns you in-game and logs detailed step-by-step fix guides if something is wrong. - Clean Live Logger (
Logger): Writes cleanly structured logs to.minecraft/logs/g1axoptimizer-latest.logwith automatic log rotation (keeps the last 3 logs to save space).
🛠️ Performance Benefits
- Reduced Delay: Up to 50% faster placement frequency on high-latency/ping connections.
- Memory Optimized: Reduced garbage collection overhead with smart object reuse.
- Coexistence Guards: Built-in boundary handlers preventing crashes with other mods. Fully compatible with:
