Its all about adding the 60Hz mode to the firmware, which will be done soon. The units support it of course. I will remind the engineers to add it in the next FW version
Indeed, even if 72Hz many times is better (24*3 for film/movie 23.976fps content)
The engineers said 50Hz is not an option at this point. May be added in future, but requires more work to get it usable. 75Hz does the same thing as 50 for old style PAL videos and EU television streams, just like Mirage said.
That solution would introduce lots of ghosting, I think.
But I think that in VR, flat film/movie watching is not as popular as VR SBS movie watching which is mostly 60 hz. So that option would definitely be great to have
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.
@Dimon
VorpX, ok, I get that. Performance is hard to get with that. Video 25Hz though will be far better served by 75Hz.
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 itâs also head shape and not just IPD hence why Kevin doesnât get any eye strain or headaches. That said, I wonder how many hours per day Kevin has to use it?
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 Iâve 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 Iâve gone on my 5k+ and on the X perhaps 3-4 hours. I would point out that Iâve 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 itâs 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. Itâs 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.
Modern headsets feature an âlow persistentâ 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 âghostingâ or âsmearâ (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) itâs reliably, and 120Hz too if possible of course.
