    Hi there.
    I am optimizing my game trying to shrink it down as most as possible for mobile platforms. I have some realtime lights on every scene and i dont need shadow, just light effect, so I was wondering if I changed the realtime lights with some particles which make light effects... would it be expensive in performance or memory????

    Particles are probably much faster.
    If you’re using deferred scene lighting then real-time lights are less expensive than with forward rendering, but still I’d expect particles to be faster in either setup.
