We will add more as we go when it is technically possible just like with the 5k+.
Like 144 Hz? Yippee! 
Just kidding. But seriously, any increase in fps would be very welcome.
Ok, deal DSC 60/72/75 Hz and 50 Hz
DSC = display stream compression

Thank you for confirming this!
Thank you for pointing that out. There may also be some uses for 64Hz - IIRC it had noticeably less tracking latency than 64Hz, and matched up some higher frequency OS kernel tick rates, so might be a good compromise between 60Hz/72Hz for flight sim.

VorpX, ok, I get that. Performance is hard to get with that. Video 25Hz though will be far better served by 75Hz.

Please don’t forget that 60Hz is needed for watching “special” movies which shoots in huge amount exactly with 60fps ))
Great review evertec thanks. A shame you will sell it, but yeh the eye strain thing is not something you can ever get used to or hope it goes away. I think it’s also head shape and not just IPD hence why Kevin doesn’t get any eye strain or headaches. That said, I wonder how many hours per day Kevin has to use it?
Not just VorpX.(20 chr)
Just think of the improvements we saw to the 5K+ hardware since launch through software and firmware updates. I hope we see the same for the 8KX and the new peripherals.

Of all the headsets I’ve had (pretty much all of them) the DK2 gave the the most trouble with headache etc. My OG Vive also gave me trouble but to a much lesser extent.
In a single session about 5hrs was the longest I’ve gone on my 5k+ and on the X perhaps 3-4 hours. I would point out that I’ve also tested defective returns that quickly gave me eye strain in a matter of minutes, one of them in particular gave me rather serious trouble for hours.
Any headset can give you trouble if it’s not dialed-in well. This is why I think the Pimax Experience is such a big deal as it not only guides the setup but gives you the best settings for each title. It’s still a bit crude right now but by the end of the year it can easily be the best VR setup tool out there. Even in the current state its quite awesome.

Personally, I’d rather have a 120 Hz mode, which would be just as good for 60 Hz videos, since each frame would be shown exactly twice.

240hz for watching “the hobbit”

For this, you can use the upscaler.
for normal films, it makes no difference which modus is used.

Modern headsets feature an “low persistent” display which is a technique to turn on the backlight to show the picture only for a short period of time. Then it stays off. Oculus introduced it first in the dk2 and it was a massive improvement of “ghosting” or “smear” (depends on definition). Pimax used shutter glasses in the p4k to have a similar effect. Because if the head is moving and the picture is still displayed, it seems to us as if the picture would move with the head moving, inducing nausea.
So yes, i notice flicker when using 60Hz in my Odyssey or pimax. I can not see any flicker at 72Hz.
Second problem is to achieve a desired brightness because of the low persistent mode - the off time period is longer.

But with 8K videos I fear about enough of GPU power. And no difference between 60Hz an 120Hz. Only if Brainwarp(Smart smoothing) will make intermediate frames? Anyway I think we absolutely need 60Hz (in native mode) it’s reliably, and 120Hz too if possible of course.

It’s not for “Hobbit” dude.

I see. I didn’t know that. In this case definitely low frequency can produce different negative effects.
Playing a film requires only a fraction of the computing power of a complex 3d application

But with 8K quality (czvr for ex) and 120Hz It can be too much to handle for low budget cards…

Imo, VR is too much to handle for low budget cards.

He is right, video is low demanding, BUT when it’s 8K video and 120Hz then maybe maybe low budget starting to not handle…
It seems that overall Pimax headsets have the reverse RiftS problem.
My IPD 70mm was too wide for RiftS and I would always strain or have one eye out of focus.
It seems that you have the same issue being of a low IPD with the PImax. Mike from Freality also suffers the same issue and it seems it turned him against Pimax for good.
I guess getting Mike a 8kX would not change his mind about PImax based on what you are experiencing
