Youtuber Cycu1 has published a detailed video comparison Cyberpunk 2077 version 1.61 with standard RTX effects and an improved RTX Overdrive mode. It was shown by Nvidia a few months ago.
The video breaks down footage from the RTX Overdrive trailer. The game will get better reflections and lighting effects. Now in the puddles it will be possible to consider each element of the reflected objects.
RTX Overdrive will be a free upgrade Cyberpunk 2077, which will add many new effects. It will probably be released this year along with the Phantom Liberty expansion.
With it, the game will also receive support for DLSS 3.0 in order to seriously increase performance on the new generation of video cards.
Cyberpunk 2077 available on PC, PS4, PS5, Xbox One and Xbox Series. A release date for Phantom Liberty remains unknown.
