Funny, Only a very select few games have had frame rate issues on PS4, and they're all third party developed titles with bugs that ended up falling on the developers themselves; not the console. All of Sony's AAA first party titles thus far have looked amazing and have run amazing as well.
Without the day one patch Bloodborne wasn't a solid 30fps either, and while not first party, it is a Sony funded and first party owned title. I've also head Knack not being 30fps either. Little Big planet 3 has bugs even after the day one patch. Don't even get me started on all the Sony funded Vita ports.
I do wish Sony and other devs put forth the effort to polish their games like Nintendo does, not having to download a day one patch.
