Lomka
Lomka is a lightweight client-side optimization mod for Minecraft. It boosts FPS and reduces lag by optimizing multiple subsystems: block-entity and entity frustum, occusion culling, OpenGL state management, NBT processing, network packet handling, and chunks processes - all without changing gameplay or breaking visual quality.
Java 25 is recommended!
