    Same vfx with Unlit quad output. Why does happed? Do I need to change any hdrp setting to optimize vfx graph when used with hdrp?

    Hi, I'm not sure I understand your concern.
    You are spawning by the looks of it a lot of particles, and are getting different FPS between lit and unlit particles?

    If that's the case, lit particles are significantly more expensive than unlit ones and as a result it would be expected that they'll take longer to render.

    Please let me know if I'm not understanding your question correctly.
