I don't hate the oculus its just not my user preference. A combination of my sight (somewhat normal) & ipd i don't find the level of outer distortion on the lens that some folks like yourself reported.
@crony has done some impressive things with the PiMax using Valve's laser tracking through OSVR.
With both Valve & Oculus opening up the tracking systems. It would be interesting using them with the PiMax.
I do agree there are physical issues that can't be fixed by software. Adjustable focus & hardware ipd adjustment. But you have to admit all vr headsets have some big issues including vive/rift. For the first product release from PiMax it is quite good; deepoon has had to get to their 3rd headset to get it closer, but they have still some big issues.
The focal length on tge PiMax is likely made short as it was initially intended for normal & short sighted folks; adjustble focus would have avoided this pitfall.
Their seems to be probably an equal number of folks on both sides that have found better user experience going in both directions.
Vive/rift = vr sick Pimax better
PiMax = VR sick. Vive/rift better
All comes down to pure user experience & not the spec sheets.
In one way should blame sharp for not making tge 4k panel a quatro. Lol
