My IPD is close to 70ish coming up from 69 o.0. What's your IPD and does a 2mm IPD difference on the low side of yours make a massive difference in clarity? It's a lot to ask but my only hesitation pulling the trigger on the G2 is that I'm out of the IPD setting range, but many people say that ±2mm should be okay. Thanks so much if you can test this out for me at some point!
The IPD is only one factor in finding the sweet spot. The fit of the headset and the shape of your head/eyes will all play a part. So nobody can really tell you how it will work with you. There will be people who have a 70 IPD who will say it's perfect, there are others who won't be able to play at all.
For VR, the only sure way to know is to try on the headset yourself. I would imagine you will be fine, most people are fine. You haven't too much too worry about, you can buy one, try it for a few days and if it doesn't work for you, send it back.
