Technical Architecture

Rendering Engine

We've replaced the antiquated vanilla renderer with a custom pipeline featuring Sodium and ImmediatelyFast, delivering up to 3x higher frame rates.

Threaded World Gen

By integrating C2ME, world generation and chunk loading are offloaded to multiple CPU cores, removing the "waiting for chunks" experience.

Logic Optimization

Lithium and ModernFix optimize internal game ticking, reducing the "MSPT" and ensuring a responsive environment.

Memory Efficiency

Advanced entity culling and FerriteCore work together to keep RAM usage minimal, allowing for massive render distances.
