I still have massive judder issues with 60 FPS videos in DeoVR on Oculus Quest.
Oculus Quest can be switched into a 60Hz mode, which I assume turning off the 72 FPS switch is supposed to enable, but it doesn't seem to have any effect on playback.
Here's how to test for playback judder:
Download

and upload the ft-60.mp4 to you Quest.
Play it in DeoVR and you'll see the moving objects in the video jumping, especially the cars driving sideways.
Play it in SKYBOX VR Video Player, and the playback, while not perfectly smooth, is significantly less juddery.
I hope your team can find a solution to make DeoVR playback 60FPS videos in Sync with the 60Hz Display mode, since that's essential for playback Quality.
