Budget for those ports were probably way higher than this one, considering QD is now multiplatform. Not the first time QD makes a game for PC too.
Wait....so, Quantic Dream which is indipendent had a higher budget for porting their own games, and two of them were actually running on PS3 compared to PS4, while Sony and Horizon had a lower budget for Horizon PC version? That's a nice conclusion you are coming up.
Quantic Dream latest engines were made exclusively for PS3 and PS4 and their last PC game was released 15 years ago. Stop making excuses for a bad porting.
