Trapcode Particular
The Rendering group controls how particles render.
This option lets you choose how the particles look when they render. There are two Render Modes.
Particular can take advantage of the additional power of your graphics card (GPU) using GPU acceleration. In the Acceleration pop-up, you can select whether to use the CPU or GPU (graphics card) for graphics processing. Accelerating with the CPU can sometimes be more reliable, but accelerating with the GPU can speed things up quite a bit.
When using GPU acceleration, there are two options in the GPU Particle Rendering drop-down.
Note that Streaming will not render some features, such as mixed Blend Modes. When Streaming is used and unsupported features are applied, a warning will appear, and Particular will use Direct rendering.
This control will quickly change the amount of particles shown for previewing. This is especially useful when the Emitter > Particles/sec control is keyframed.
