What's new

FastValus 5.0.1 - FULL build (Forge 1.20.1) - tested on a real Forge 1.20.1 server.

Included: mob / item frame / dropped item / XP orb / minecart / display culling (walls + behind camera, map walls kept), block entity culling, name tag culling, particle flood limiter, unfocused FPS limiter, 128-chunk render distance slider, live HUD (/fv hud), benchmark, video presets (/fv boost), loot-safe ground item sweep, per-chunk entity limiter, distant idle mob AI throttling, /fv + client-only /fvc commands.

Fixed in 5.0.1:

  • Dedicated servers on non-1.20.1 versions no longer log 3 ERROR lines per second.
  • XP orbs, fireballs and dragon fireballs keep their vanilla glow when culling is enabled.
  • More reliable Forge 1.20.1 detection (reads the real Minecraft version).

Note: on Forge 1.20.2-1.20.4 this file runs the LITE engine. The per-chunk entity limiter removes mobs above 35 per chunk by default; raise maxEntitiesPerChunk or disable it in config/fastvalus-common.toml for big farms. FPS gains depend on the scene (storage halls, farms and explosions benefit most).
