Nvidia CEO Jensen Huang’s Top 5 Remarks From GTC 2022
Nvidia CEO Jensen Huang touts the ompany’s RTX 40-series GPUs, the Omniverse and other innovation at the online GPU Technology Conference.
Now Comes DLSS
Each frame of a CGI [computer-generated imagery] movie takes hours to render. We want to do this in real time. Nvidia RTX opens the world to real-time ray tracing [the technique for modeling light transport for use in many rendering algorithms for generating digital images]. RT cores do BVH traversal [bounding volume hierarchy uses a short stack of just a few entries] and array triangle intersection testing which saves the SMC [system management controller] from spending thousands of instructions on each array. But even with RT cores, frame rates were too low for games. We needed another breakthrough.
Enter deep learning DLSS. [Deep Learning Super Sampling is a family of real-time deep learning image enhancement and upscaling technologies developed by Nvidia that are exclusive to its RTX line of graphics cards, available in many video games] DLSS is one of our greatest achievements. Ray tracing requires insane amounts of computation. DLSS uses a convolutional auto encoder AI model and takes the low- resolution current frame and the high-resolution previous frame to predict on a pixel-by-pixel basis. …The process is repeated tens of thousands of times until the network can predict a high-quality image.
