As stated by CapFrameX, the game may receive a new technology called Real-time Neural Radiance Caching for Path Tracing. This is a topic of a paper published by NVIDIA researchers in 2021. In short, this is a method of replacing model pretraining with generalization via adaptation. What this means is that the model will not be pretrained for specific surfaces for where light sources bounce from but will adapt on the fly and will train while rendering.
This real-time caching for radiance can be used for path-traced global illumination that enables dynamic content prediction. This technology is compute-intensive and requires fixed hardware support like Tensor cores, but it does need as much memory as existing models.
