Hi there,
In my project i am using the particle system for the effects. Right now i am working for a android platform, when i enable the particle system my fps rate is reduce half its getting down from 60 to 30 and below that also.
If i dont enable the particle system scene going on the same fps rate.
So please help me how to optimize the particle system for the android platform?
Thanks.
Are you using mobile particle shaders?
yes, i used both shaders but no use. Still frame rate is getting damage.
look at the render part of the particle system, and make sure they do not cast and receive shadows because if you have a light in your scene that will get a bit of “damage” to your frames 
i change the mobileparticle shader and uncheck the receive shadow. its helping, now i my frame rate is reducing 60 to 40 if i enable the particle.
Can i make it more frame rate better than this?
Are you spawning a large amount of particles ?
yes, little more. I am creating the dust particle which is available in the scene until the user press the button.
