[Gear VR | Go] Noticeable performance degradation

XR SDK

-

Unity 2019.1.0a11 has worse performance on Gear VR than other recent versions. This is noticeable to a lesser extent on Oculus Go. When moving my head quickly I see dropped frames or judder in several simple scenes.

    I have seen this in 2019.1.0a12 with a simple scene from a 2018.3.0f1 project that runs at 72fps with extra headroom. It also happens if you import the Oculus Integration (both 1.31 and 1.32) into a new project and build & run the trivial "Oculus\VR\Scenes\Room" test scene.

    Every few seconds there is disruptive judder for several frames.

    The Remote Oculus Monitor profiler is giving me an "out of order frame index (prev = x, new = x+2)" warning. This coincides with a predictable pattern of one or two very short "WarpSwapInternal" calls (~3ms) and then a very long one (~26ms). This is happening with a GPU/CPU utilization at ~45% and ~55% respectively.
