// Load as much data as possible, as a result frame rate will drop.
// Good for fast loading when showing progress bars.
//装载尽可能多的数据传输速率，因此帧将下降。 
//加载时显示出良好的快速进度条。

// Load data very slowly and try not to affect performance of the game.
// Good for loading in the background while the game is playing.
//加载数据速度非常慢，尽量不影响游戏性能的。 
//在游戏进行时有很好的后台加载。
