The Xbox One could one day make use of a powerful rendering technique called "real-time ray-tracing," an advanced system used to achieve photorealistic lighting effects. Microsoft Studios executive Phil Spencer has confirmed that internal tests are already underway.
"We've done experiments with Realtime Raytracing," Spencer said on Twitter. " A ton of potential with this tech; amazing visuals." You can see a video demonstration of Nvidia's Kepler real-time ray-tracing system on YouTube courtesy of The Verge.
