Intel researchers showed off a ray-traced version of Wolfenstein:
Research project Wolfenstein: Ray Traced gets demonstrated inside Intel Labs in Santa Clara, CA. See the highly detailed chandelier model with near realistic glass reflecting and refracting with amazing clarity. Also see a shiny car reflect movement from its surroundings, and other potential game-play enhancing features. The demo setup consists of four machines using Intel's Knights Ferry card as rendering server that feeds a small laptop with the stunning visualizations playing at a high frame rate.
