Gotta love it when a 'tester' tells someone that their problem does not exist because he does not see it and, for that reason alone, will not be reported.
The physics of binocular vision, in a VR headset, has nothing to do with IPD but is directly tied to the spacing of the two virtual cameras used to generate a 3d perception. The fact that some devs choose to ignore this reality does not make it correct.
