admin Jet-Pack (IPACS) Hi, just want to bring to your attention that there is still a bug with Vulkan when using Oculus Quest devices with their pc-link cable. It's what the user in this thread was having an issue with, and it has been commented on in several other posts here with people not knowing what the real issue is.
The effect is this: if you are running with Vulkan enabled, launched into the native Oculus VR build (*not* steamVR), then the rendered scene is VERY laggy with head movements. Any normal-speed head movements cause an effect where the world rendering is extremely delayed, and as a result the outside view gets dragged along with your head motion. Instead of the cockpit and scenery remaining fixed while you move your head, they move with your head at a variable rate.
I tried to record this on the 2D mirror, but it only shows up in the headset. The mirrored desktop view looks completely normal.
If you change back to openGL rendering, the issue goes away completely, and the app is its normal extremely-fluid performance at 90fps.
I was one of the users who used to have the problem of the Vulkan Oculus build going straight to a black screen, until your update a few months ago fixed that issue. However I'm wondering if this is still somehow related.
My system is a 1080Ti GPU, i7 8700k CPU, and MSI Z370 Gaming Pro Carbon AC motherboard. I wondered if this was an Nvidia driver bug with my older 1080Ti card, but the user above has an RTX3070, so it's affecting newer cards as well.
