What's new

FastValus 5.1.1 - Universal JAR (one file for Forge / NeoForge / Fabric / Quilt, MC 1.12 - 26.3).

Hotfix 5.1.1 (Crash-Shield):

  • SafeGuard session circuit-breaker isolates every client & server hook so unexpected mod interactions never crash Minecraft.

  • Deferred FMLClientSetupEvent + ForgeConfigSpec.isLoaded() guards prevent early modpack splash-screen config race crashes.

  • Pure-vanilla + zero-Mixin-duck-interface renderer check + auto-yield prevents ClassCastException with Create, Flywheel, Oculus, Iris, ImmediatelyFast, EMF/ETF, Supplementaries, Amendments, Lootr & Immersive Portals.

  • Strict Forge 1.20.1 version verification + hardware-safe render distance slider cap (prevents VBO driver crashes and -128 packet disconnects).

  • Zero blocks, zero items, and zero commands added by default (100% safe on any server).

  • On Forge 1.20.1 (FULL build): Options & Video Settings GUI (FastValus..., compatible with Vanilla, Sodium & Embeddium), 56-rule Mod Conflict Detector, culling suite, particle limiter, HUD, presets, item sweep, chunk limiter & AI throttling.

  • On all other versions (LITE engine): 56-rule Mod Conflict Detector (logs/fastvalus-compatibility.txt), automatic self-yielding, particle flood limiter, safe render distance unlock, unfocused FPS limiter, and ground item sweep.
