NVIDIA had their customary GTC keynote ending mere minutes ago, and it was one of the longer keynotes clocking in at nearly three hours in length. There were some fascinating demos and features shown off, especially in the realm of robotics and machine learning, as well as new hardware as it pertains to AI and cars with the all-new
Jetson Nano. It would be fair to say, however, that the vast majority of the keynote was targeting developers and researchers, as usually is the case at GTC. However, something came up in between which caught us by surprise, and no doubt is a pleasant update to most of us here on TechPowerUp.
Following AMD's claims on software-based real-time ray tracing in games, and Crytek's Neon Noir real-time ray tracing demo for both AMD and NVIDIA GPUs, it makes sense in hindsight that NVIDIA would allow rudimentary DXR ray tracing support to older hardware that do not support RT cores. In particular, an upcoming drivers update next month will allow DXR support for 10-series Pascal-microarchitecture graphics cards (GTX 1060 6 GB and higher), as well as the newly announced GTX 16-series Turing-microarchitecture GPUs (GTX 1660, GTX 1660 Ti). The announcement comes with a caveat letting people know to not expect RTX support (think lower number of ray traces, and possibly no secondary/tertiary effects), and this DXR mode will only be supported in Unity and Unreal game engines for now. More to come, with details past the break.
