More clarity in VR, especially past the ~20/20 readability of the Pimax Vision 8kX, is about improving both comfort for long-term users, and learning curve for newer users briefly using the headset.
From the Pimax Vision 8kX, for what the image quality looks like, we are just at the point of diminishing returns. Much higher resolution and much less blur will not look so much different, because we close to average human vision.
Yet, being only as good as human vision does still cause some slight eyestrain. Better lenses will reduce blur (especially towards the edges), better resolution will improve the speed of readability. Both better lenses and higher resolution are still an important end goal for VR.
For long-term users, this may be a difference of 10hours/day instead of 12-18hours/day, and some minor aches from more head movement. From new users, I sometimes hear complaints, sometimes due to expectations of VR optical clarity already being exactly equal to ‘IRL’, sometimes due to impatience with the time taken for a person’s own eyes to adjust.
I think the Pimax 12k, especially if the center area high resolution projector becomes available at any price, will help improve the amount of hours VR developers can work solely in the headset, and the number of users who can get into VR. That in turn, will improve the usability of software in VR. So this is very important.
On a side note, everything I can do that I seem to need to at this point - whether hardware/software design, or exploration and competitive gaming - is already ‘virtual’. So optical quality - both from resolution and lenses - is vastly more important to me than the sort of transparent displays used for ‘see-through’ AR. For getting to my chair and keyboard, camera passthrough is very appropriate. So I would also say that higher display resolution, better lenses, and lower distortion, that VR headsets should continue to have over transparent AR glasses, makes those VR headsets far more important to me.
