Why does enabling _multiDrawInstances in BatchedMesh drastically reduce performance?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
The _multiDrawInstances property is null by default according to the official documentation.
I'm wondering if the underlying multiDrawArraysInstancedWEBGL WebGL feature inherently suffers from performance issues, or if there's another cause for the slowdown when using it in BatchedMesh.

WebGL Multi-Draw Features in Three.js
Based on the available documentation, I don't have specific information about the _multiDrawInstances property or performance characteristics of the multiDrawArraysInstancedWEBGL WebGL feature in relation to BatchedMesh.
The Three.js documentation provided doesn't contain details about:
- The
_multiDrawInstancesproperty - Performance characteristics of
multiDrawArraysInstancedWEBGL - Specific implementation details of BatchedMesh related to these features
To get accurate information about this topic, you might want to:
- Check the Three.js source code directly for implementation details
- Review the WebGL specification for the multi-draw extensions
- Look for performance benchmarks or discussions in the Three.js GitHub repository
- Consult the Three.js forum or Discord for developer insights
The BatchedMesh class is documented in the Three.js API, but the specific internal properties and performance characteristics you're asking about aren't covered in the documentation chunks available to me.
