If things look warbled for you when you turn your head, you can fix that.
But first you need to do this:
Save this image to your desktop.
Open it and zoom in on image until it fills your whole monitor.
Fire up pimax and put on.
Open desktop view and walk up until image of this grid fills your whole vision.
Now go ahead and lift your hmd higher up your nose and lower.
The horizontal lines on outer left and right?
The bend upwards, and when you raise your hmd more the bend lower.
Those horizontal lines need to be flat all the way horizontally, and when they do, your hmd is on at the proper height.
Nice at proper height, faster your hmd secure.
Notice? A lot less distortion when turning your head. Like, a lot less.
Pimax def needs to tweak the distortion profile because I think the outer parts compress a bit but it’s really an easy fix, but that disheartening distortion is a whooole lot less.
You may want to set this grid as your desktop or something because calibrating the height you need the headset at is really important.
