If 2D doesn't cut it for you, you can try watching some of the events through a VR headset. For Samsung Gear VR owners, NBC is providing 85 hours of delayed VR coverage that includes the opening and closing ceremonies, basketball, gymnastics, track and field, diving, boxing, and fencing. The content isn't free -- Gear VR owners can view the coverage via the NBC Sports app after signing in with a paid cable account. But the BBC is also providing some VR coverage through the BBC Sport 360, which will work with the Gear VR as well as lower-cost headsets for Android and iOS devices. It's not clear yet if the BBC coverage will be available worldwide; its broadcasts are usually limited to U.K. audiences.
