ff14 VR is this a thing ?

That was a joke. The PS3 can't even handle Mor Dhona/Idylshire properly, let alone Oculus/VR

To be fair the PS4 struggles with populated areas too, rendering the game twice would cause the performance to plummet unless they add an option to lower the visuals to something on par with how the PS3 has it. Not just the PS4, most, if not all low to mid-end PCs will struggle in raid environments and populated areas. 30 FPS isn't enough for anything longer than 10-60 minutes of gameplay (I guess it will vary from person to person, but everyone has their limits. Here are a few quotes from the found of Oculus (if you're not aware, Oculus are pretty much the guys who started this recent VR trend).

For VR you need much higher frame rate than you need on a typical screen.
60 frames per second is definitely enough. You see huge improvements up to 90 and 120hz, and even beyond that you can see small improvements.
Virtual reality is going to need much higher frame rates than consoles.
Although even for consoles or traditional PC games I don't think 30 frames per second is smart. It's not a good artistic decision, it's a failure.
