A method for implementing a graphics pipeline. The method includes generating a system of particles creating an effect in a virtual scene, the system of particles comprising a plurality of particle geometries. The method includes determining a subsystem of particles from the system of particles, the subsystem of particles comprising a subset of particle geometries taken from the plurality of particle geometries. The method includes determining a foveal region when rendering an image of the virtual scene, wherein the foveal region corresponds to where an attention of a user is directed. The method includes determining that at least one portion of the effect is located in the peripheral region for the image. The method includes rendering the subsystem of particles to generate the effect.
