API and Library Performance

Performance Results (by testing):

FPS Improvement: ~5%-30%

Lag spikes reduced: ~10%-20%

 

How?

- Entity Render Culling – skips rendering distant entities, reduces shadows & animations

- Block Render Culling – skips rendering distant heavy blocks like chests, signs, banners, and spawners.

- Particle Limits – limits particles and dynamically scales them based on FPS.

- Chunk Render Optimizer – throttles chunk rebuilds to prevent sudden frame drops.

- Memory Optimizer – monitors memory and triggers smart garbage collection to avoid lag spikes.

Fully Configurable – every system can be enabled/disabled with clear, easy-to-edit settings⚙️.

Works on any server, with any modpack, without affecting gameplay mechanics or causing conflicts.
