The hosts provide an overview of realtime pathtracing and NVIDIA's advanced graphics technologies, focusing on how they enhance the visual fidelity and performance of video games. Finally, they first explore real-time path tracing in Unreal Engine 5, highlighting how this technology allows for more realistic lighting and shadows by simulating the way light interacts with the environment. The talk also describes NVIDIA DLSS and NVIDIA Image Scaling, explaining how these techniques use AI and algorithms to improve image quality while maintaining high frame rates. Also they delves into the NVIDIA Image Scaling SDK, a tool that allows developers to integrate spatial upscaling into their games across various platforms. The hosts talk on Shader Execution Reordering (SER), an API that optimizes ray tracing performance by reordering shader execution.
