It sounds like some of the bigger issues are still present in the V5, but I think Pimax can fix them. I noticed the same suggestion a few times, that I prevuously suggested.
@xunshu you guys should experiment with a lower field of view. This would mitigate distortion and Mura, increase clarity and PPD, and might even help you get up to 90hz.
200 degrees is amazing, but only if these issues can be fixed.
Now that you have windows MR and Vive pro offering competition at better quality, anything you can do to provide the BEST all around experience, just makes good sense.
