Draw calls v2.2

Hello,

I have some doubts about the usage of spreadsheets in cocos 2dx v2.2. I would like to improve the performance related to draw calls and opengl. I’ve seen that in cocos 2dx 3.x, it already has an improved render system with RenderCommands that are ordered and optimized to minimize the draw calls and so, but what about the older version 2.2?

Right now I’m not using anything like spreadsheets, SpriteBatchNodes, … Just using CCSprites directly. This should ending up in doing a draw call for each sprite in scene, which are lots.

Do you think I should start using texture atlases or what’s the best approach to improve my game?

Thanks
