NVIDIA will talk about Q2VKPT, the Vulkan-based renderer for Quake 2 that uses hardware accelerated path tracing and advanced spatiotemporal denoising. The speakers will cover some of the implementation details, including things like importance sampling, lighting, materials, and the denoising filters. In addition, NVIDIA will discuss the challenges of using a physically based renderer with the assets from a game released over two decades ago.


Real-time path tracing is possible today... sort of.

Intended Audience

Graphics programmers and everyone else who likes Quake 2 and/or ray tracing.
