Q2VKPT [is] an interesting graphics research project whose goal is to create the first entirely raytraced game with fully dynamic real-time lighting, based on the Quake II engine Q2PRO. Rasterization is used only for the 2D user interface (UI).
Q2VKPT is powered by the Vulkan API and now, with the release of the GeForce RTX graphics cards capable of accelerating ray tracing via hardware, it can get close to 60 frames per second at 1440p (2560×1440) resolution with the RTX 2080 Ti GPU according to project creator Christoph Schied.
The project consists of about 12K lines of code which completely replace the graphics code of Quake II. It's open source and can be freely downloaded via GitHub.
This is how path tracing + denoising (4m16s video) works.

What's "realistic" is defined when the NN is trained. Once in grasp of the "reality", it can be made to an insane amount of HDR or pastel colors or just gamma or whatever.
