Caustic has another video online where their CTO and co-founder James McCombe demonstrates a real-time rendering of a VGA-resolution scene at 4-5fps. The demonstration shows a 5-million triangle scene of a few cards with full ray-tracing (Primary, Secondary, and GI rays) and using procedural GLSL, trilinear filtering, and antialiasing.
