I'm sick of people saying the PS4 can't output 1080p at 60fps. It can easily do this. The reason games don't run at that is that the game engine is using graphics that are too complex to run at that rate. It all depends on how nice you want the graphics to look. You could take any PS3 game and run it at 60fps at 1080p on PS4 and it would look awesome in VR. Don't expect VR games on PS4 to look the same as the games you play on a flat screen because flat screen games are much less dependant on a constant frame rate. However a drop in frame rate when playing in VR can cause motion sickness, so it makes sense that VR games will look a little simpler but run much smoother and therefore give a better experience.
