FPSFlow

[1.8.1]

Added

• Lithium-inspired performance optimizations — FPSFlow 1.8.1 integrates several key optimization techniques adapted from CaffeineMC's excellent Lithium mod, reimplemented from scratch to respect Lithium's license and ensure full compatibility with the FPSFlow codebase:
  • Compact Sine Table (CompactSineTable.java) — A memory-efficient sine LUT that reduces table size from 256 KB to 64 KB using trigonometric identities (sin(-x) = -sin(x), sin(x) = sin(π/2 - x)). Reduces CPU cache pressure during rotation-heavy rendering while maintaining bit-for-bit compatibility with Minecraft's MathHelper.
  • Direction Constants Caching (DirectionValuesMixin.java, FastDirection.java) — Prevents repeated defensive array copies from Direction.values() in hot code paths by providing cached references. Every call to Enum.values() in Java creates a new array allocation; this optimization eliminates that overhead in frequently-called redstone, block update, and entity collision code.
  • Fast BlockPos Utilities (FastBlockPos.java) — Thread-local mutable BlockPos for iteration contexts plus efficient long-packing for hash-based collections, reducing GC pressure in chunk scanning and neighbor-iteration hot loops.
  • Collection Helper (FastCollectionHelper.java) — Pre-sized HashMap/HashSet factories with optimal initial capacities, identity-based sets for entity classification, and utility methods that avoid the common allocation pitfalls found in vanilla's collection usage.
• Full Lithium attribution — All adapted code paths include Javadoc @see references and Inspired by comments linking to the upstream Lithium repository.

Changed

• Version bumped to 1.8.1 — Gradle property mod_version updated from 1.8 to 1.8.1.
• OptimizationManager module list extended — New lightweight utility modules are registered on startup (no tick overhead, no Minecraft class dependencies).

Fixed

• None.
