Now I'm not much of an Opera fan. The idea of watching a bunch of people sing in Italian (great if you're Italian) is not my idea of a fun night. However, developer Kite and Lightning have created some significant effects, atmospheric music and mixed that into an amazing VR experience.
The Senza Peso site shows you wonderful pictures and behind the scenes photos and art. The Oculus is a little different but still excellent.
The Senza Peso mini Opera will turn anyone into a VR Opera fan.

Onto the geeky part. Senza Peso is developed with the Unreal Engine 4. Epic has stated this engine is designed with VR in mind so exciting times ahead.
Performance wise it ran well on my Machine with a GTX 780. During the boat scenes, there was a little judder if moving head fast (Just turn slower)
Easy. Running the Rift in extended mode was no problem.
