A couple of months ago, Crytek unveiled his Neon Noir technical demo, which showed real-time tracing using hardware outside of Nvidia’s RTX. With this it showed an independent solution of API or brands to offer viable raytracing techniques. It is an impressive demonstration, and the use of an RX Vega 56 and not one of Nvidia’s RTXs seems like black magic. Luckily, Crytek you have given details about the happy demo and how it was carried out.
To begin with, it ran at 1080p and 30 fps at the points where reflections worked at their highest resolution. At the points where the demonstration showed reflections at half resolution, it ran at just over 40 fps and 1440p. This could be added to the advantages of Vulkan or DirectX 12 for better results, of course. Indeed, the company has seen that with the effects of the Nvidia graphics such a demo could run with all the effects of raytracing at a 4K resolution and show even more dynamic objects. That is, CryEngine will be able to democratize the effects of ray tracing, but it will also take advantage of specialized hardware optimizing the experience.
To show the reflections by ray tracing, the company has created a method that allows them to switch between mesh and voxels without losing quality, which drastically reduces the cost of performance of this class of techniques. Ron Frolich, Crytek, you have ensured that in just two months the technical demo has improved greatly in terms of implementation of raytracing, with a greater number of refractions, light reflections and also improvements in performance and quality. It is expected that this new version of the CryEngine will arrive later this year.
