It really depends on the intensity of the particle though, using a tyre smoke particle my game goes very slow(with your setup), but using my own particle(which i'm gonna show you in not too long) you wont see literally 1fps difference from without any particle.
That's pretty rad tho, i have managed making a goku-supersayian-ing-like particle earlier today lol.
