So if I understand the anti-CA IPD vs. the overall optical IPD, this might explain why some folks think the G2 is great and others can never get enough sharpness around the sweet spot. If the central optical IPD is 64 mm +/- 4 mm and the anti-CA IPD was designed to be at ~64 mm, perhaps if your IPD is right in the middle, you’ll think the G2 sharpness is great whereas if you’re off to one side, you won’t be so happy even with physical IPD adjustment if the anti-CA optimum is fixed right in the middle distance.
My best IPD measurement with the free iOS EyeMeasure app that requires a recent iPhone with RealDepth face recognition abilities is 63.7 mm and I set my physical IPD to 64.4, as the slight increase seems to help. And I now think, wearing my normal prescription glasses and ignoring the off-center progressive bifocal part, that central vision sharpness is great for a VR headset.
So it would be interesting to hear from folks who have IPD’s at the extreme what they think of G2 central vision sharpness. Maybe just as when folks talk about graphical performance in MSFS and give their rig specs, when folks remark on some VR headset sharpness, they should give their IPD, whether wearing glasses, contacts, reading glasses, or using unaided vision, etc. Otherwise, a declaration of good visuals or bad is like talking about poor FPS in MSFS without revealing the hardware behind it!
