If you use a "Utility Mod" (like Meteor or Aristois), it may already have a built-in crystal optimizer that conflicts with this standalone file.
The "fabric" suffix in the file name indicates the mod's environment. Unlike the older Forge loader,
Walksy Crystal Optimizer (Fabric) — reduces client and server load from crystal entities by batching updates, adding LOD rendering, and providing compatibility hooks for other mods. Configurable and safe by default.
