FPSFlow

[1.6.0]

Fixed

• NPC nameplate flickering — Entities whose nameplate visibility has been set to always-on by the server (isCustomNameVisible = true, typical for plugin NPC systems) are now exempted from distance culling entirely. Previously the mod fought against the server metadata update on every view-distance change, causing persistent flickering.
• Hysteresis reset every 200 ticks removed — The periodic full cache wipe in NameplateCullingManager was resetting the hysteresis dead-band, causing a brief nameplate flicker roughly every 10 seconds for entities near the culling threshold. WeakHashMap garbage-collects despawned entity entries automatically, so the manual wipe was never needed.

Added

• Background FPS limiter — When the Minecraft window loses focus the frame rate is capped at a configurable limit (default: 60 FPS unfocused, 30 FPS minimised) via a post-frame sleep on the render thread. Inspired by Dynamic FPS. Caps are profile-aware: Quality 30/10, Balanced 60/30, Performance 10/3, Ultra Performance 5/2. Toggle via backgroundFps.enabled in the config.
• Painting back-face culling — Paintings are never visible from behind, so the renderer now skips them entirely when the camera is on the back side. Uses a dot-product normal check against the painting's facing direction. Controlled by entityCulling.paintingBackfaceCulling (default: true).
• Tiered particle density LOD — Instead of a hard allow/block cutoff there are now three distance zones: near (< midDistance): 100 % of particles; mid (midDistance → maxDistance): ~50 % via a stable position-based hash — no per-tick flickering; far (> maxDistance): 0 %. The new midDistance value is configurable in all four built-in profiles and custom profiles.
• FPS-adaptive LOD tightening — When the adaptive renderer detects low FPS (< 30 FPS: 0.7× multiplier, < 15 FPS: 0.5×), entity LOD distance thresholds shrink automatically. At 20 FPS the Balanced thresholds (40/80 blocks) behave like 28/56 blocks without requiring a manual profile switch.
