SpriteBatch -> 2x performance improvement anyone?

[sake]

I've just tried SpriteGroup and I see some kind of flickering when I apply modifiers to my TiledSprites (MoveModifiers and FadeIn/FadeOut Modifiers). Switched back to normal sprites only (still got more than enough fps )

Hi,
I'm using old andengine GLES1.
I just found out about SpriteBatches and it should greatly improve our application. But I couldn't make it work...
But after some struggling, I manage to find that the problem is that SpriteBatch doesn't work with BuildableTextureAtlas ! You can find TestActivity which only shows blackness here...

Is there a way to make SpriteBatch work with BuilableTextureAtlas ?

Thanks for the awesome work !
Regards,
Florian

so the conclusion is spritebatch does not support rotateModifiers, moveModifiers , right? besides this, it is cool!
or we can only use bitmapTextureAtlas for a single sprite and use Spritebatch with modifiers?
