And how do you explain the fact I've never suffered ingame nausea?
I played Subnautica for 3 hours in a row, I play ViveCraft for hours, I watch many 360º videos, and I do not feel nauseous.
I play all my "non VR" FPS in 3D SBS on Pimax 4K and I've never felt nauseous.
I got a reduction in the light bill and basically got a chronic pain in the neck by replacing my 42-inch monitor with the HDM. No nausea.
Am I more resistant to motion sickness than most? maybe, but that does not change the fact that compared to me, you have fragile stomach.
The truth is that there are many people with a fragile stomach.
I want logical arguments, after all, you are trying to transform a subjective truth "it is true because it happens to ME", in an absolute truth "is a defect in hardware". My "I use for 3 hours in a row and do not feel nausea" proves that it is an ORGANIC problem, not technological, after all, my friend bought a RIFT and felt nauseous after 4 minutes.
"The truth of what we see directly is only one. On the other hand, the truth of what the human being makes in his mind, aiming at the construction of numerical abstractions, the visualization of patterns and transformation of it into a reality, similar to that of objective truth, will present many nuances and the choice for that fragment that you fancy it, it will be a subjective choice".
My 78-year-old mother uses Pimax to watch when I'm playing Skyrim, for example (she finds it interesting to walk passively in beautiful virtual landscapes) and watch several 360 videos (screen moves constantly), and she never felt nauseous. 78 years old.
