Good news, I'm getting the same double vision on my Vive at home.
Does your double vision go away if you put the clip board away?
HiTech
With the Vive
Yes. In the tower I do not have double vision until I move the cursor off the board then the cursor is doubled. If I then put the board away the cursor becomes normal.
In the plane I do not have double except for the gunsight and on the wing as explained below. The clipboard being up or down does not change anything.
When I turn my head to the left or right, as I increase the angle the wing splits into two images and the higher the angle the more the images separate. I didn't notice that before on the right wing because my neck doesn't work as well in that direction. If I look at the wings with just my eye movement with a small turn of my head, it appears to be normal.
As to Vulcan's request to scale the tracking, if you do that please make it user selectable. I kinda like 1to 1 as that's what is realistic. I just do what real pilots do, I sit-up and turn my body.
