At least 100k particles

Hi!

So my goal is to generate procedural galaxy, I already have the code for that part, I instantiate prefabs for each stars at the right position to form the arms of the galaxy. But I want the galaxy to have at least 100000 stars. Is there a way to render so much particle (or something else) with relative good performance ? With particle system the limit seems to be 2000 stars, after that I'm droping at ~30fps with my computer.

Someone have an idea ?

Thank u!
