Interesting...to this day C2077 remains one of the worst optimized PC games right? Yet they don't hesitate to add graphic features that take even more processing power.
Path tracing is significantly more taxing even on high-end RTX 4000 GPUs compared to traditional ray tracing methods. Nvidia's real-time neural radiance caching for path tracing is designed to solve the severe performance hit. This new AI-accelerated method has been in development for a couple of years now and the first implementation could soon be featured in the Cyberpunk 2077 expansion Phantom Liberty.
