The Visual Effect Graph is a package that you can use to create large-scale visual effects for your Unity Project. The Visual Effect Graph simulates particle behavior on the GPU, which allows it to simulate many more particles than the Built-in Particle System. If you want to create visual effects that include a large number of particles and need highly customisable behavior, use the Visual Effect Graph instead of the Built-in Particle System. For information on how to install and use the Visual Effect Graph, see the getting started guide.
