Yeah, I have to agree; it feels like he has said too much.
It does sound like there are some big issues. I'll go out on a limb and say that I don't think the problem is the lenses at this point. I'm thinking there may be compatibility issues with games (which were never designed for such a wide field of view), the need for a top-of-the-line GPU to avoid stuttering, and maybe issues related to the lower 80 Hz framerate.
Time will tell, as to what the issues are, if any. I do hope Pimax takes the time to fix any major problems and does not rush this out the door.
