OptiCores

Asynchronous Culling: Offloads heavy rendering math to a background thread to prevent CPU stuttering.

Primitive Data Sets: Uses FastUtil IntOpenHashSet instead of standard Java maps to eliminate memory leaks and "garbage" collection spikes.

Double-Buffering: Implements a lock-free "swap" system so the main thread never has to wait for background calculations.

Adaptive Item Culling: Automatically hides dropped items and XP orbs at shorter distances to prioritize framerates in crowded areas.

Platform Target: Engineered specifically for NeoForge 1.21.1 on integrated graphics (Intel UHD/Iris Xe).
