Earlier this week I put in Home windows 11 – however as a VR consumer I already remorse it.
It’s not that it’s a nasty working system. The truth is, relating to utilizing common purposes and video games I already desire it to Home windows 10. The design is clear, trendy, and much more constant than the visually discordant mess of Home windows eight & 10.
However as quickly as I attempted utilizing a Quest 2 to play PC VR by way of Oculus Hyperlink, my appreciation for the brand new OS disappeared. Transferring my head or fingers I observed a continuing visible juddering, sufficient to make me really feel illness inside a matter of seconds. The problem occurred each with native Oculus titles and SteamVR, and throughout each wired Oculus Hyperlink and wi-fi Oculus Air Hyperlink.
I instantly suspected a efficiency concern, however each the Oculus Debug Software and any in-game efficiency counters confirmed no dropped frames. My system was sustaining 90 frames per second with no drops. So what was responsible for the stuttering?
By switching by way of the modes of the Oculus Debug Software I rapidly found the Oculus compositor itself was dropping frames (within the screenshot above my headset was set to 90 Hz mode). Should you’re not aware of the time period, the compositor is the always operating software program service VR app sends its rendered frames to. The compositor applies timewarp or spacewarp when wanted, overlays system UI, and makes positive to ship frames to the GPU on the proper time. The compositor ought to at all times be operating on the framerate of the headset’s refresh price – if it isn’t, one thing goes badly mistaken.
A fast Google search exhibits dozens of different Quest homeowners reporting precisely the identical concern on Reddit and the Oculus boards.
Making an attempt Digital Desktop as an alternative, I discovered the identical concern in native Oculus titles. However utilizing Digital Desktop with SteamVR, the problem went away. I didn’t expertise the stuttering anymore and Digital Desktop’s efficiency overlay exhibits no dropped frames. That’s in all probability as a result of, whereas SteamVR passes its frames to the Oculus compositor when utilizing Oculus Hyperlink, Digital Desktop as an alternative has its personal OpenVR runtime.
I’ll discover potential options to this drawback over the weekend. If I can’t discover one, I’ll revert to Home windows 10.
Should you too took the gamble with Home windows 11 this week, tell us the way it went within the feedback beneath.
