Thanks for all the great work on the Oculus Browser! I believe I'm seeing significantly worse positional tracking in the WebVR browser compared to native apps.
Note: MoonRider is one example, but it happens generally with any WebVR app. For example in https://aframe.io/aframe/examples/showcase/anime-UI/ if you move your torso left/right while looking at the white circles against the blue background
I tried toggling the 'highRefreshRate' flag but it appears that's already set automatically (if I measure the FPS it's 72). And I tried 'foveationLevel' but that didn't help either.
