60 Hz refresh rate?


#1

Will the 5K/8K models support 60 Hz refresh rate (or some multiple of 60 Hz)?
When watching 60 fps movies you get less judder if the refresh rate is 60 Hz. I rarely see this problem mentioned, but it’s something I really care about. I have an Oculus Rift and a Gear VR and the latter definitely plays 60 fps movies smoother than the Oculus, because the Oculus is fixed at 90 Hz (which forces it to e.g. show odd frames for 11.1 ms and even frames for 22.2 ms, instead of showing all frames for 16.7 ms).

I know Pimax 4K supports 60 Hz, and I will get one if 5K/8K won’t support 60 Hz, but I’d rather wait for 5K/8K otherwise. (I also read that the 4K model will get updated hardware very soon. I hope that doesn’t mean it won’t be able to use 60 Hz anymore!?)

Any comments about this would be appreciated.

Added xunshu. It was requested due to Optimus laptops that pass through intel igpu. I can’t see why not as it will help those users & provided Brain Warp works well could give those users a perceived 120.

i distinctly remember the original spec being 60/75/90 120/150/180 w brainwarp.


#4

But… the M1 has Brainwarp?


#5

The 60 was added after a user mentioned the optimus scenario. But we haven’r heard much on it since


#6

Well thats the software side & haven’t heard much on it. I presume the m1 might be testing that in the beta test. But will have to wait & see.


#7

do you seriously want the pimax 4k which doesn’t have positional tracking, and a fov of just 110…? just because the pimax 8k might not support 60 hz?


#8

Few ways to add positional tracking including possible valve tracking.

As he mentioned thogh it has to do with Movie watching he said he found on Rift jitter in playback of 60fps. Where the GearVR does a better job being 60hz.

I really do want 60 Hz, yes. And you don’t really need positional tracking for watching movies. Also, I’m actually a bit skeptical about the 200 degrees FOV. Maybe it’s me, but my Rift looks worse the further from the center I look, and my Gear VR even more so. I think I’d rather have perfect looking 90 degrees than 200 degrees with lots of blur and artifacts, if I had those two options. (But I’m not sure.)

All VR headsets seem to have their problems, and some people experience problems that other don’t, with certain headsets. And given the rather extreme specs of the Pimax 8K, I’m afraid it might have more problems than other headsets. I hope they prove me wrong, though!

Maybe I’ll get the 4K and the 8K. :slight_smile:

I think with 200 degrees FOV if you see some thing out the corner of your eye even if not in focus you will turn your head to see what it is, but with current HMDs you cant see it, you have to turn your head first to see if anything is there.

@xunshu

Second this. Support for 60hz is a must (most VR video is shot at 60hz)

Can we get confirmation that the M1 will support a 60hz option?

Any update on this? It seems like it would be easy enough to do…
