Erik c715e55937 docs: datLock-contention FPS fix design spec ... The 30↔200 FPS swing is _datLock contention: the streaming worker holds the global dat lock for the full per-landblock build (lockwait measured 24ms median / 88ms p95), stalling the update thread's ApplyLoadedTerrain. Fix (A1): the worker pre-reads the apply's six Get<T> sites into a physics dat bundle so ApplyLoadedTerrainLocked makes zero DatCollection calls and its lock(_datLock) is removed. Approved design; implementation next. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>		2026-06-23 09:22:20 +02:00
