 This is handled nowadays by a type of technology called "streaming". It means that assets are pulled from disk on demand (loaded only at the time they are needed), rather than as a part of a larger stage. The most common types of streaming are:
 
 * **Texture streaming**: All textures are loaded in a tiny size by default. As textures get closer to the camera, higher resolution versions (or mip-maps) are streamed from disk. Textures which haven't been used for some frames are freed instead. At any given time, the textures loaded (and their detail) closely reflect the place the player is in.
-* **Mesh streaming**: Models are loaded as low detail (few vertices). As they gradually approach the camera, higher resolution versions are streamed from disk. Models that were not used (displayed) since a while are often just freed and will be loaded again when needed.
-* **Animation streaming**: Modern games have long cinematics, which require a lot of animation data. Loading those animations require a lot of memory and loading them takes a lot of time. To avoid this, animations are streamed by generally keeping the first second or two in memory and then new sections are loaded on demand as the animation plays. Godot 4.0 supports strong animation compression and animation pages, so most of the work is already done.

 * **Audio streaming**: Similar to animation streaming, it requires storing the first second or two of audio and then streaming the rest directly from disk.
 
 Of the above, most are relatively straightforward to implement. The most complex is *mesh streaming*, which generally needs to be implemented together with a GPU culling strategy to ensure that very large amounts of models can be drawn at no CPU cost. This is more or less what techniques like *Nanite* do in Unreal, although Godot does not need to implement something that complex to be of use in most cases.

 Still, the scene system (which uses those servers), despite several usability improvements, has not seen significant optimization.
 
-Scenes nodes in Godot are mostly intended to carry complex high level behaviors (such as animation trees, kinematic characters, IK, skeletons, etc.) for limited amounts of objects (in the hundreds at most). Currently, no threading happens at all and only a single CPU core is used. This makes it very inefficient.

 This makes it an ideal target for optimizing with multithreading. There is [an initial proposal](https://github.com/godotengine/godot-proposals/issues/4962) on threaded processing for scene nodes, which should give complex scenes a very significant performance boost.

 More experienced programmers can use the servers directly or even plug C++ code to do the heavy lifting. ECS is often also proposed as a solution for this. Even GPU Compute (which is fully supported in Godot) can be easily used to solve this pattern.

 While for very large studios this is not an area of interest, medium-sized studios still rely on significant amounts of assets and pre-made functionality. The Asset Library currently existing in Godot only links to open source resources (e.g. hosted on GitHub or GitLab) and is unable to be used for commercial assets.
