The only thing that is not 1:1 is the CV bridge. That is do to an issue of using a different bridge then the original was designed for. We shrank it pre VR and you can not notice do to projection. But in vr it obviously is noticeable.
If you are seeing a change from previous VR use, or some thing on your system has changed, or a setting you are using is showing a bug.
