I have performance issues with the SLR app when playing 4k videos on Daydream with my Pixel 3 XL. The videos never play at a smooth 60fps, but seem to playback at much less than that. Maybe 30fps or less. Video are still watchable, but framerate is less than ideal. It happens when streaming video or downloaded ones. If I were to download a scene trailer from the app and play it back in another video player (like Skybox), the video plays smoothly at 60fps. Is this a general performance issue with the app on Daydream?
One thing to note though, is that videos that can be viewed using viewport playback, seem to run smoothly. Is there any timeline when more videos will support this? It seems only a few scenes support it at the moment.
