I have the rift,the rift is simply a tablet/smartphone display strapped to your face with built in tracking,nothing more.The rift has absolutely nothing to do with sound in a game,that is dictated by the game itself,the rift does not add or take away from the sound of any game.If half-life 2 has awesome sound in the rift it's because it has awesome sound even without the rift.Also if you had 100 percent realistic sound in DCS all you would hear is very loud engine noise that sounds muffled because you are wearing ear protection,so I wouldnt worry about accurate sound for DCS.
