I try to draw rain and snow as particle system using Core Graphics. In simulator rendering proceeded fine but when I run my app on real device rendering is slow down.

So, advise me please approaches to increase particle system drawing performance on iPhone.

May be I should use OpenGL for this or CoreAnimation?
