78 FPS CPU limit on a 13900k is abysmal.
The game is obviously going balls to the wall on RT which likely has a massive CPU cost. Obviously coming from CB2077 devs we can assume it has some pretty crazy RT settings designed specifically for top end hardware only.
Personally I've no problem with this as long as the settings can scale down smoothly to more normal hardware (like Cyberpunk).
The DF analysis should be interesting, especially the console matched settings.
