Pimax Crystal and XRToolkit providing technical information

[NuVen]

In PimaxPlay I changed the Horz offset from L:0.0 R:0.0, which reads in XRToolkit, at a LR:41.7 RL: -41.7. I think, this means a binocular overlap of 83.4 degrees.
If the horizontal offset is adjusted to L:-0.3 R:-0.3 (both values are negative) that reads in XRToolkit at a LR:42.4 RL: -42.4. Again, a binocular overlap of 84.8 degrees.
This adjustment reduces the Horz FOV from 103.4 to 101.8 degrees while increasing the binocular overlap.

 

Human visual binocular overlap is about 120 degrees, and our visual system has that much FOV to construct a spatial image.

 

The Pimax Crystal Super 50 ppd has an advertised binocular overlap of 105 degrees. 
Still less overlap than available in normal vision. 
Using the motorcycle helmet analogy, if I reduce my FOV by holding my hands up to the left and right of my eyes the full binocular overlap is still available to my visual system.

 

The customer base is requesting more FOV, hence the latest Ultrawide option. The binocular overlap is reduced to 90 degrees to achieve the wider FOV.
Just suggesting the standard 50 ppd Crystal Super might be a good balance for flight sim.

 

They are asking for customer feedback. Their business identity seems to be an engineering-achievement priorities first. I have had the Pimax Crystal for about 1 3/4 years. The performance of the HMD has improved during that time. Some of their marketing claims have been discarded, modified or not entirely met. However, the performance right now, at the price point is better than their competition. The marketing dialog is ahead of schedule sometimes, but I am not so upset by that.

Good summary.

I have a PCL and it's been a good experience overall. Pimax are a small company gaining experience, making mistakes, and I think trying to learn from it. They do not have the funding of a Sony or a Meta and if one's expectations are for that kind of backing, then buy a Quest 3 or PSVR. Pimax are not perfect, but man, I get tired of all the dumping on them.

Don't do that; this makes you a little cross-eyed, or opposite (v-eyed). It is hard to recognise small error with slight adjustment, but after a few days of playing  you will eventually recognise that something is off. 

 

 And search ww2 goggles; they didn't have good overlap at all. example:
