What It Does
G1axFixer prevents game crashes caused by corrupt, broken, or oversized resource packs while adding client-side performance optimizations for crowded servers and modpacks.
Resource Pack Crash Guard
- Corrupt ZIP Protection — Prevents crashes from broken resource pack archives.
- Atlas Overflow Fix — Safely handles oversized textures exceeding GPU limits.
- Missing Sprite & Sound Handler — Replaces missing textures with fallback placeholders and skips corrupted OGG audio files without crashing.
- Model & Language Repair — Substitutes broken 3D models with fallback cubes and skips malformed translation JSON files.
Performance Optimizations
- Particle Culling — Cull distant particles to maintain 60+ FPS in combat and heavy encounters.
- Network Packet Batching — Batches network overhead to reduce multiplayer latency.
- Entity Render Optimization — Optimizes entity and tile-entity rendering at distance.
