Cyberpunk 2077 got off to a rocky start in 2020, but the development team has gone to great lengths to fix the game and implement as many features as possible in a relatively short amount of time. Now, it looks like NVIDIA and CD Projekt RED are working to add another new feature, known as “Real-time radiance caching“.

The game currently supports ray tracing, which has now been upgraded to a “full version” with RT:Overdrive mode. Cyberpunk 2077 is also one of the few games that supports all modern scaling technologies: DLSS3, FSR2 and XeSS. How Expectations With CapFrameX, the game can receive a new technology called Real-time Neural Radiance Caching for path tracing. This topic is dedicated Articlepublished by NVIDIA researchers in 2021. In short, it is a method of replacing model pre-training with generalization with fitting. This means that instead of pre-training the model on specific surfaces that reflect light sources, the model adapts on the fly and learns as it renders.
This real-time irradiance caching can be used to track the global illumination path, enabling dynamic content prediction. This technology is computationally intensive and requires fixed hardware support such as tensor cores.
Neither NVIDIA nor CD Projekt RED have confirmed that such technology could appear in the game. The technology is set to be added to the upcoming Phantom Liberty DLC, which is rumored to be coming in June.
