Using this SDK for watching 360 videos, the experience is pretty jumpy.
Movements in the video happen with the slightest uncontrollable hand
movements.

We had this problem in another application, and the experience was greatly
improved just be reducing the accelerometer frequency from 60 Hz down to 15
Hz.

Can this library expose the frequency as a setting? I guess in the latest
IOS, this is the CMMotionManager.accelerometerUpdateInterval.

We are also seeing this issue on the iPhone 6S. Compared to the Google VR Android SDK it's very jumpy. A fix, or a parameter that we can tune ourself would be appreciated.

In v0.9.0 we removed any head tracking prediction which should help. So I'm tentatively closing this.

Please feel free to re-open if you think that's not good enough :)

When rendering in monocular mode with v0.9.0 we're still experiencing very sensitive/jumpy head tracking compared to Android. Especially when rendering in portrait mode. It improved quite a bit, though.
