Hi,
There are two rectangular dark patches (like a shadow) that move as I move my head.
The two rectangles are I think 180 degrees from each other. If I'm flying at right angles to them then I don't notice them so much, but sometimes they are in front of me.
I have uploaded two images showing this rectangular artifact.
The first shows a rectangle clearly. The second shows the rectangle in the distance where the runway is (not so noticable in this image, but it does move rapidly as I turn my head - even small head movements, and is distracting).
Altitude might affect how the rectangles are shown.
I've noticed these for several months now.
Hopefully you can fix them.
I'm using the Vulkan Engine.
Aerofly FS 2/4 is the best flight sim for VR in my opinion.
Looking forward to future updates in scenery resolution
Nick
