If I use a large number of sprites in the application, it slows down (FPS decreases). Tell me, please, what graphic format is better to use to optimize the speed of application? Which is faster?
Must it be compressed? Or is it better to use uncompressed format?
What is best to use if I don't need an alpha channel? Or if on the contrary, it is necessary?
My priority is the speed of the game, rather than the final size of application, so I'd like to know, what is the format processed more faster?
