   Hello, I just started using Cocos2D for my project which is an isometric game. I went through the samples and then ran them on the device and noticed that all of the tile examples reach 60FPS (was testing on a 3G) except for the isometric example with the trees which was 16-17FPS, and the third example only 30FPS. I was just curious as to why the performance is so low especially in the first example?

   Thanks.

   I was looking into the code more and I'm guessing this is because the map is much larger and with more overlapped graphics than the others so I'll have to look into how to improve this. Has anyone else dealt with this?

   yes, the isometric maps from the samples are very big and they have 2 layers., that's why it performs somewhat bad.

   try not to render big maps (split them in smaller maps) and try to use only 1 layer.

   So if I wanted a larger map the best thing to do would likely be to cut that up into smaller maps like you said and then display them only when needed correct? Almost like a paging concept.

   I have worked with isometric code before, but I indexed them differently. I ran my columns West to East, not NW to SE. That seems to make culling quicker, which may or may not be the underlying problem.

   @imperil: I suggest to try your map without optimizations. If it is slow, then, 1 possibility is to use "paging".
