Terrain Loading Priority Fix

Description

By default, Valheim loads the structures in a massive base completely at random. When you cross a zone boundary, the game engine pulls data from your save file and scrambles it into memory.

When you cross a grid sector boundary, Valheim's database manager (

ZDOMan) queries your world save file. It extracts thousands of raw data blocks called ZDOs (Zone Discovery Objects). These ZDOs are completely flat data packets—they are not 3D visual assets yet; they are just numeric coordinate maps stored in RAM.

The native engine divides these raw files into two temporary pointer groups:

• []currentNearObjects(ZDO data strings inside your immediate base sector grid)[/]

  []currentDistantObjects(ZDO data strings sitting out on the far horizon)[/]

  Step 1: The HarmonyX Memory Interception

  Normally, Valheim hands these two raw lists straight to the rendering manager. This mod places a high-speed

  patch on this exact method footprint, explicitly matching Valheim's modern signature. By gaining direct, read-write authority over Valheim's active internal data arrays the exact microsecond they pass through the creation gate, the mod handles incoming data loops with zero processing overhead.

  Step 2: Zero-Allocation SortToken Pool (New in v1. 4. 0)

  In previous versions, running an inline or static altitude sort over live queues forced the CPU into an unmanaged-to-managed bridge bottleneck, calling

  a. GetPosition().ymultiple times per object and causing micro-stutters during heavy chunk loads.

  Version 1. 4. 0 completely eliminates this issue by introducing a pre-allocated

  SortTokenmemory pool. The algorithm now extracts the height (

  y) of each individual ZDO packet exactly once per data pass. It then runs a lightning-fast primitive float sort directly on those saved values inside a local RAM cache, dropping ongoing sorting latency down to zero and eliminating frame-by-frame heap allocations.

  Step 3: Decoupled Global Update Hub Sync

  Built with an intelligent system check that silently scans game memory for your Global Update Manager. The exact millisecond it is detected, the mod automatically aligns its sorting cycles with your main frame context ticks, guaranteeing your plugins never compete for CPU cycles or create loading-thread pipeline cross-talk.

  Step 4: The True Ground-Up Load Order

  The algorithm reorganizes the active list indices so that a ZDO with a low altitude value (like a stone foundation footing) is pushed to the absolute front of the array index. A ZDO with a high altitude value (like a roof apex) is pushed to the back of the queue index.

  Because Valheim is forced to process these arrays from lowest to highest, your bases visually and physically stream in from the ground up. Foundation anchors, structural walls, and pillars are guaranteed to lock into place before the upper floors and roofs load. This removes the random chaos of vanilla chunk loading, preventing your massive multi-story structures from taking physics damage or smashing apart on loading screens—all with zero impact on your frame rate or real-time streaming performance!
