We talk with NVIDIA's Tom Petersen about how ray tracing works, with some specific information on real-time ray-tracing. Ad: Buy the EVGA X299 DARK on Newegg (https://goo.gl/rcwkwY) Article: https://www.gamersnexus.net/guides/3279-real-time-ray-tracing-explained Real-time ray tracing has been "the next big thing" in gaming (and cinema) for what feels like forever. We first covered some nVidia predictions on real-time ray tracing in games around ~2012-2013, when the company projected an equivalent to RTX happening around 2015. That, obviously, was a few years early, and we're now revisiting the topic in 2018. Now, with Tensor cores in Volta architecture, nVidia is able to render real-time ray tracing at 4K60 on about $12,000 of graphics cards, and the company almost assuredly intends to move this down to more consumer-affordable hardware in the future. In this video, we talk about how real-time ray tracing works, including examples of ray tracing (many made by GN) in Unreal Engine or Blender. The real-time aspect is what makes 3D graphics hard to render, and what we're mostly talking about today. We have a new GN store: https://store.gamersnexus.net/ Like our content?
