When I run a half dozen particle systems on an iPod 4th gen, the frame rate drops about 15-20%. I am wondering if there are various optimizations for particle systems. I am emitting a custom sprite at moderate life lengths and speeds. So, in other words, I am not doing too much fancy with them.
Obviously, I may just do an animation, but am wondering if there are some good optimization tips.
Cheers.
2 words… “particle pooling”.
ParticleSystems are not all that efficient when you’re talking about using multiple systems at once. The best performance optimization I’ve found is to instantiate different particle systems exactly once in your scene, and then to edit the systems during runtime to put particles where you want them to be… unfortunately this requires a bit of coding on the user end but it helps the performance quite a bit.
Hm,
I am not sure what you mean.
All of the systems are identical.
