An anonymous reader writes: A recent article in American Scientist describes the battle between Intel, AMD, and NVIDIA for the next generation hardware that will serve all our graphics needs. At the SIGGRAPH conference next week NVIDIA will present OptiX as their future platform for ray tracing entirely on GPUs, while Intel and AMD will be showing KeyShot which is entirely CPU driven. Around the corner AMD's Fusion architecture looks very interesting as well. Who will win this battle for realtime rendering? And when will we see ray tracing in games?
