I played through Dead Rising 3, which I enjoyed a lot more than I ever thought I would, and if the frame rate did drop, I either didn't notice or didn't care. Fun is fun. Like Vinny said, it holds up pretty good considering all the zombies on screen. Sometimes frame rate just doesn't matter to some people.
My cousin plays COD Ghosts on his PS4. Every time I've been over, the drops in frame can be kind of bad. But either he doesn't notice. Or doesn't care. He enjoys it.
Good for him and good for you, but other times framerate and other performance areas do matter which is why I regret absolutely nothing by going deep into PC but at the same time I'll watch the new consoles from a distance to see which one ends up getting their shit together.
I'm not paying money on anything that is going already going to show its age this early in the life cycle. New Halo game being promised to run at 60 fps is the one holdout game I'm keeping my eye on to see whether or not anyone can salvage some kind of comparable performance to the PS4
