Gecko Lib Animation Optimizer Mod (1.21.1, 1.20.1) – Stop Lag When Fighting

Gecko Lib Animation Optimizer Mod boosts game performance by optimizing how GeckoLib entities render in the world. This client-side mod lowers animation updates for distant mobs and skips rendering creatures hidden outside your camera view. It keeps your frame rates stable when exploring areas filled with custom animated monsters.

Features:

• Slows down animation tick rates for mobs that are far away from your character.
• Stops rendering creatures that stand outside your camera field of view.
• Includes an optional wall occlusion setting to hide mobs behind solid blocks.
• Provides custom blacklist and whitelist filters for normal mobs and bosses.
• Protects boss fights so their animations stay smooth during combat.
• Prevents animation slowdown on whichever mob you look directly at.
• Runs on your game client without needing any server-side setup.
• Lets you adjust settings through an in-game config menu or the configuration file.

Configuration:

• config/geckolib_animation_optimizer-client.toml: change animation distances, culling options, and mob whitelist filters.
