With this demo Crytek shows raytracing in realtime without using dedicated hardware such as we see with Frostbite and NVIDIA's RTX line-up in Battlefield 5.
Neon Noir shows how real-time mesh ray-traced reflections and refractions can deliver highly realistic visuals for games. The Neon Noir demo was created with the new advanced version of CRYENGINE’s Total Illumination showcasing real time ray tracing. This feature will be added to CRYENGINE release roadmap in 2019, enabling developers around the world to build more immersive scenes, more easily, with a production-ready version of the feature.
Neon Noir was developed on a bespoke version of CRYENGINE 5.5., and the experimental ray tracing feature based on CRYENGINE’s Total Illumination used to create the demo is both API and hardware agnostic, enabling ray tracing to run on most mainstream, contemporary AMD and NVIDIA GPUs. However, the future integration of this new CRYENGINE technology will be optimized to benefit from performance enhancements delivered by the latest generation of graphics cards and supported APIs like Vulkan and DX12.
This eliminates the known limitation of pre-baked cube maps and local screen space reflections when creating smooth surfaces like mirrors, and allows developers to create more realistic, consistent scenes. To showcase the benefits of real time ray tracing, screen space reflections were not used in this demo.
