Is something like SteamVR's Async Projection always on?
We have an app that was written for SteamVR, and are testing it on the Samsung Odyssey MRD headset. We are finding that the frame rate often fluctuates between 90, 60, and 45 fps, but rarely at a value in between. I am wondering if there is something like Steam's Aync Reprojection or Interleaved reprojection (or ASW on Oculus) always on for a MRD headset? In the SteamVR's settings, "Async Reprojection" is "off" when we run our app, and the checkboxes to allow reprojections are also off (makes not difference in the frame rate as far as I can tell)
If there is some kind of frame-rate limiter always on, is there a way to turn it off when running through SteamVR? We would like to get raw performance numbers so that we can directly measure the performance impact of the Samsung headset so we can determine how & where to optimize to hit 90fps all the time.
