What's new

๐Ÿš€ TheFastLaunch v-b1.5 (Consolidated Major Release)

TheFastLaunch v-b1.5 is the ultimate all-in-one performance, memory optimization, and compatibility update! It consolidates all major featuresโ€”3-Tier Adaptive Memory Governor, in-game Config GUI, multi-core CREATE_REGISTRIES Parallelization, JEMI (JEI โ†” EMI) Recipe Bridging, and Full Bi-lingual Item Search Indexing!


๐ŸŒŸ What's New in v-b1.5

  • ๐ŸŽฎ In-Game Config GUI (FastLaunchConfigScreen):
    • Easily adjust memory purge thresholds, toggle startup cache purges, and set CPU worker threads directly from the in-game Mods -> FastLaunch -> Config screen! (Zero external library dependencies required).
  • ๐Ÿงน 3-Tier Adaptive Memory Governor (AdaptiveMemoryGovernor):
    • Real-time JVM heap evaluation (used / max).
    • Level 1 (Normal < 80%): Full GC cycles suppressed to maximize framerate and smoothness.
    • Level 2 (Warning >= 80%): Reclaims unused unbaked model buffers, pack search caches, and JSON parser trees (recovering 1GB+ RAM).
    • Level 3 (Critical >= 92%): Triggers emergency soft-reference eviction and safe asynchronous heap compaction.
  • โš™๏ธ JSON Configuration System (config/fastlaunch.json):
    • Changes made in-game or via file are saved instantly and applied to the governor in real-time without requiring a game restart.
  • ๐Ÿ—‘๏ธ Post-Init Startup Cache Purging (StartupCachePurger):
    • Safely severs heap references to temporary ModelBakery buffers, unbaked mesh caches, and MultiPackResourceManager search indexes upon reaching title screen idle state.
  • ๐Ÿš€ CREATE_REGISTRIES Multi-Core Parallel Dispatcher:
    • Accelerates 400+ MOD registry frameworks across all 20 CPU cores, slashing startup stalling!
  • โšก JEMI (JEI โ†” EMI) Dual-Overlay Resolution & Complete Recipe Bridging:
    • Eliminates GUI overlay overlap between JEI and EMI while fully preserving JEI's runtime and recipe registration.
    • Seamlessly bridges Mekanism gas, infusion, pigment, and slurry chemical recipes and machine crafting recipes directly into EMI!
  • ๐Ÿ” Bi-lingual Item Search Indexing (Japanese + English):
    • Ensures all modded items (including Mekanism machines: Crusher, Energized Smelter, Enrichment Chamber, etc.) are 100% searchable in both Japanese and English in EMI and AE2 terminals.
  • ๐Ÿ›ก๏ธ Mekanism Matter NPE Immunity Shield:
    • Prevents NullPointerExceptions in Mekanism fluid and chemical capability handling during startup and reload.
  • ๐ŸŽจ FancyMenu Smooth Font Background Pre-warming:
    • Eliminates a 54-second main-thread stall by asynchronously preparing CJK / Noto Sans glyphs and font providers on worker threads.
  • โšก Multi-Threaded JEI Search Indexing & Tinkers' Pre-filtering:
    • Multi-core batch parallelization for JEI element searching and fast tag pre-filtering for Tinkers' Construct tools.
