I am trying to create Graphics v2 version of my game, but I am having performance problems after replacing imageGroups (which has been removed in Corona G2.0) with normal display groups
In the Corona display.newImageGroup() Docs page we can see:
This function has been removed. In the V1 graphics engine, this was used to optimize batching for objects that shared the same underlying GPU texture.
Migration:
In the current graphics engine, you can achieve the same level of batching by placing the same objects as children in a group. As long as the objects all use the same image (or imagesheet), the engine will be able to batch them as before.
Then I am replaced newImageGroup() with newGroup() without additional changes (then migration conditions seems to be performed). With the old graphics this game was 60 frames but now is very choppy. Game using three tile layers which two of them was as imageGroups, now them are normal Groups using this same imageSheet as before in imageGroups. Of course the game is using additional graphics, not only one image sheet. Tested on Build 2014.2126
