Deferred Lighting / Particle System

Here is a shot of a GPU based particle system with lights attached to each particle. I used Emil Persson's example Deferred Shading program as a basis to implement a Light Pre-Pass renderer with 4k lights and 4k particles. It runs fairly well on a GeForce 9600 GT here:

    I'm assuming that this is DirectX10?

    Looks nice Wolfgang. On a related note, which technique do you use for rendering point light volumes to the light buffer?

    Cool. Any difference in performance vs. the original deferred shading implementation?

    I intend to use the final demo for my SIGGRAPH talk. Until then I will work on it and I will have more detailed performance data until then.
