1. We can't identify what is wrong with your code based only on knowing that it is running slowly. I recommend you post the code that is run each frame.
   
2. I wouldn't worry about which file format is faster. The texture should only be loaded once, either when the program starts or when it is first needed. Once a texture is loaded, it is stored as a texture, not a PNG, BMP, or whatever. So unless you are experiencing an extraordinarily long load time when the program starts, I wouldn't worry about which format loads the fastest.

do not dispose the texture as that releases its resources and will need to be reloaded again, if you know you will be using the sprites allot, there is no need to dispose them.

 

if you have already solved it, sorry for posting to an old thread.
