In an interview done by PCWorld's Gordon Ung at GDC 2023, CD Projekt Red's VP and Global Art Director, Jakub "Kuba" Knapik, and NVIDIA's Senior Developer Technology Engineer, Pawel Kozlowski, shed a bit more light about the upcoming Cyberpunk 2077 Path Tracing update and what it brings to the game as well as what kind of hardware will you need to run it.
In case you missed it earlier, both CD Projekt RED and NVIDIA did talk about the RTX Path Tracing Overdrive Mode for Cyberpunk 2077, which will launch on April 11th. This will be a part of the Cyberpunk 2077 Update 1.62, which should bring additional gameplay improvements as well. It is worth to note that Path Tracing will be introduced to the game as a "technology preview", and as Jakub notes, as the developer is still working on this technology with NVIDIA and it is still a work in progress.
