I'm currently working on a game with more than 32x32=1024 sprites on the screen at the same time with animation and everything runs 60fps. (iPhone 6 and iPad 4th Gen) But when I introduce 2 bitmaptext objects for score and level, fps drops to 15fps. Even showing fps in render function using game.debug.text has impact on performance and I have to draw a horizontal progress bar for fps instead of text. Is there  a way to improve the performance with bitmapTexts?
