Real Time Path Tracing

Game engines are continually evolving, and with each generation they try to improve rendering techniques, the ultimate goal being  graphics that are indistinguishable from real life. Ray tracing simulates light in a realistic way by tracing each photon and how it interacts with a surface, but has only been available in 3D modelling programs with lengthy render times as they calculate each bounce. However with the brute power of today's graphics cards real time raytracing may be just around the corner.
In a similar way to how my favourite rendering program Keyshot works (hence the noise as the camera moves) this new engine uses 'Path-Tracing' to bring realistic lighting in games that step closer, it's pretty impressive.
