My Unity app loads lots of large images from a server, this causes Unity to freeze while decoding and rendering the image becuase this is all done on the main thread.

Does your code still use the main thread to load the images onto textures?

To test have a code like this

void Update()
{
transform.rotate(Vector3(1,0,0)* Time.deltatime*10);
}

Run that while loading several images using your code, see if the object being rotated ever pauses and then resume rotation.

Texture2D texture = new Texture2D(width, height, TextureFormat.ARGB32, false);
texture.LoadImage(data);

纹理创建和纹理数据载入不能在子线程中做，只能在主线程。一旦下载的图片是png、jpg等格式，LoadImage内部会解码元数据格式到ARGB32，这个是比较花费CPU的，所以图片多一些的时候，卡顿会很明显。好一点的做法考虑在收到http下载的图片数据后。自己写一个解码图片的函数在线程中计算解码。然后在主线程中把解码后的数据直接通过SetPixels或LoadRawTextureData。这样会减少卡顿。

Hello, I found your project is very promising.
Can you please provide any working sample?
