If you know how LCD technology works, you should have known that there is no ON-OFF strobing in LCD's, they just keep their state in an ON state and transition to the new state (image) when the pixel changes color, and this transition time of the pixels is reasonably slow (>20ms in real world performance).
Refresh rate IS important in my opinion....for multiple reasons, nausea management, stereoscopic view support, less eye strain etc.
Sure I am giving them the benefit of doubt, as I am as excited as anyone else to see their new wide FOV models, but the fact remains that no existing LCD technology will offer an optimal visual quality, response time, and a comparable color reproduction in VR against OLED tech.
LG and Google are close to annouce new micro OLED displays with huge resolutions and very fast response times, aimed at VR.
And I must disagree with what you said about the usage scenarios, since a VR headset should cover the most wide range of uses, from fps games to racing and flight simulators, to simple games.....building an headset with only some type of optimal target usability would severely limit the possibility to sell it to a wide audience, otherwise it can happen like in the 4K, that ended up being seen like a "4K movie watching headset" or good only for racing games, and I have no doubt Pimax learned the lesson from it.
Just my two cent critic thinking of the technology used today...I'm a fan of Pimax and support them in any way I can, but we have to keep in mind that there is always room for improvement or alternative choices, and I think Pimax should aim to the enthusiast VR market, not the cheap side of it.
