Particle system - only 1st emitter when low framerate
My particle system only uses the 1st emitter when the framerate is low. Is there any way to bypass that? Any help much appreciated.

This is likely due to the CPU being used to emit the particles, when you reach a certain cap level the engine will no longer output any particles from the emitter.
To get around this limitation you will want to move the computation of the particles over to the GPU, as it can handle many times the number of particles being emitted compared to the CPU.
A good example (and explanation) can be found in the following video by Zak here:
Also if you haven't already, I highly recommend watching the entire series he put together, it goes over everything you need to know about particles:
Hope that helps! :)
