People play this game on minimum settings with less than 30fps.
If the game required hardware for at least minimum 30 fps, more people wouldn't be able to play.
the ps4 isn't that powerful, they were just able to optimize for it, i'm not really surprised they think it has issues, especially since, in the CPU department, the PS3 was stronger.
Pretty much the only things they did in regards to minimum recommended specs was update the list with current hardware, and not obsolete, ancient hardware. they didn't really change anything other than that. It was talked about at the fanfest, if i remember right, that it was more a "no one would go out and buy something with this in it anymore, so now its more accurate for todays purchasable hardware"
