the sickness, i wonder do you get a stable 80 fps?
Dear 8k users, how many of you see the “wobble” effect that MRTV and a few others have talked about?
Yes, running on a 2080ti and top end machine and this is just beat saber so not that demanding.

This appears to be related to headset position, face shape, and padding thickness. There may be additional factors at play, but padding is something you can easily test and adjust.
Have your wife test it with the headset pushed deeply into her face. If the wobble is gone/reduced, she needs less padding. If the wobble is worse (or unchanged) try pulling the mask out from the face a little bit. If the wobble is gone/reduced, she needs extra padding.
I’ve read that some people use Vive replacement face pads, which apparently need minimal modifications to fit the Pimax. Some types of padding are easily swapped (attached by Velcro, like the stock Pimax foam pad. Search this forum for more info on changing pad thickness and which brands/types can be used with Pimax.

I’m curious if eye tracking could measure the distance to screen as well. It most certainly measures at least the ipd and variations of different asymetrical eye positions which should a more precise ipd measurement/Adaption.
But with distance to screen it would provide good data for an individual distortion profile, even using different face pads.

This is not a positioning issue but rather a display and/or tracking problem. I can hold the headset insuring that there is no extra movement and observe the issue. With the Vive doing the same thing there is zero movement. If you are at the steam VR home screen the room is perfectly anchored in place in relation to your movements. Not so with the 8k.
As this was a reported issue with the M1 units that was improved with software updates hopefully it can be improved.

Hell no! I’ve never experienced this wobble effect and enjoy my SkyrimVR with out the least thought of such an experience. Still wonder if it is on account of face shapes or improper settings or a computer that is not optimized for VR. Every time I here this “wobble effect” I just shrug my shoulders and say to this day what is it and if this stops some one from considering purchasing the 8k that is a shame. I really enjoy my 8k. While I’m writing. So much is dependent on what game or experience or app you are using. Is this "wobble or distortion found in every app? I don’t think so! You will find that certain persons will state that the geometry is off or this or that, and then you will ask them well what apps have you experienced this in and they will return with I only use my app or this app. Sure we would like to experience the best in all possible world but this really is not possible. Enjoy your 8k and if you have the funds enough available to purchase it you will have the current best enthusiast level Vr headset available to the public at this time regardless of its flaws both imagined or real imho.

Wait whaaaat? Who reported this on the 5k…?

This delay has to be because of the damn upscaler. I see this kind of delay in YouTubeVR with Oculus Rift and it makes me sick instantly. If it’s the same thing with 8K it’s a deal breaker for sure.
@deletedpimaxrep1 Some people feel sick when using the 8K because of a motion delay/latency issue… please ask the team to investigate.
EDIT: I don’t understand why I get that latency only in YouTubeVR.
It is getting harder and harder to decide between 5k+ and 8k
For me it is about which is more of a deal-breaker:
Black dots on the 5k+
Wobble effect on the 8k
I think that in the worst scenario black dots are annoying, but wobble effect will make the headset useless for some.
If it is to bet, maybe going for the 5k+ is the safer decision

Yeah, that was my reaction too. I don’t think I can find it again. (I have no idea as to what text should I search on in the forum to find it.) Iirc, it was a problem with the Pimax face pad foam not being thick enough and the user fixed it by using a Vive face pad.

No it is not. I have both my 5k Plus and 8k with same paddings, same ipd and obviously…the same face. 
People have to accept the fact that the 8k has more latency than the 5k Plus. That is also the reason why they can only run the 8k at 80hz max while the 5k Plus runs at 90hz.

I accept that, but I’m not sure that the wobble is due to increased latency. If it is, why do so many 8K users say that they cannot see it? The latency should be the same on all systems.

They probably lack the direct comparison. Just as people who are used to a Full HD TV and have never looked at a 4k TV feel their picture is perfectly fine and can’t believe it could look any better. Only once you look at a 4k TV all day long and then go back to the Full HD TV, then they will be surprised how they could actually enjoy their Full HD TV.
I suppose something similar is going on here. After using the 5K Plus for longer periods of time and then going back to the 8K, the added latency is painfully obvious.

It is not a refresh issue as the RIFT DK2 was only 75hz and it does not have this issue. The world is rock solid. It is looks a software issue, my controller movements do not seem to suffer from any lag or delay of input but only head movement.

That’s actually similar to the reason I finally chose the 8K.
My wife uses my old IPS monitor; I’ve been using a TN 4K monitor; initially the colors seemed a little drab, but I got used to it. When I recently used my wife’s IPS monitor, the colors seemed practically fluorescent (in comparison to what I was used to). I realized then, that I would never really be happy with the 5K’s blocky, weak colors and poor black level (unless I could do a comparison in person).

Man I’ve been following your flip-flops for weeks! 
This post is only minutes old so I think I now know your final decision! … for now that is! I’ve been in the same boat. I really got tired of beating it to death and just told them to just send me the 8K I signed up for originally. … for now!

I think the reference to the 5k having the ‘wobble’ is more about the geometry moving when you’re eyes are further away from the device lens’ - but that’s different to the 8k ‘wobble’
For what it’s worth - I see that geometric movement in the Rift, too. It’s more to do with position of HMD in relation to your eyes - basically you can see outer edges seem to bend a little as if it’s a lens based warping, as if you’re looking through the wrong part of your glasses. But the VR space is anchored properly, and static. It’s the same as the 5k+ in that regard.
With the ‘wobble,’ the entire VR space is dragged from side to side with your head - or, you could say the entire space stays still for a moment/delay when you move your head…

I have always leaned toward the 5K+ since the very moment it was revealed (because sharper at equal GPU load, or less GPU load at similar sharpness (although the 8K can’t be exactly as sharp) ).
Recently the black dots thread has made me “almost” consider maybe switching to the 8K (for the 1st time).
But yesterday I went to a VR chat I haven’t visited for a while, and some people received their pimax (5k+) and said the black dots are a non-issue as they are very hard to notice (only visible when you focus on the panel/SDE. As soon as you look into the VR world (= focus beyond panel/SDE) the black (grey in fact) dots are not visible).
So I’m 100% confident again the 5K+ is the right choice (for me, being looking for the best sharpness, including at distance).

First up, they’re not even ‘black’ dots, they’re a lighter shade of whatever colour they’re on. Secondly, as yet I’ve only been able to see them on reddish/orange colours, and you can literally change your focus to see and reveal them by choice… They’re definitely not over everything. It’s a minor issue

Simply because people have varying sensitivity to latency.
The same as some people are perfectly fine playing with a low framerate and can even claim it is perfectly smooth.
The day I received my plasma TV (a good one, panasonic) and was the 1st time I could see this tech in action I have noticed so many flaws that were never reported in any professionnal review nor user feedback (and I have read A LOT). And I never got used to these flaws and still see them after years (but that TV can still amazes me, despite those flaws).
A could also talk about black levels from this TV that are universally described as perfect, with people saying they can’t see the difference in black level between the black bars and the TV bezels. But I cleary see those are not perfect black, just very deep grey (and my TV has been calibrated). So don’t ask me what I think about people saying the pimax black are fine, I know how sensitive I am so don’t build hopes on such claims. I’m already prepared to have far less good experience than my current rift in dark scenes (but that’s a tradeoff I accepted from the beginning when I have decided to enter the KS).
Back to sensitivity to latency, I can imagine many people being not sensitive enough to see it, and it seems true given the feedbacks we have now.
So the conclusion (at least mine, which I believe being objective) is the latency is there and you have a fair chance to not notice it. Then the only remaining question is: would you take the risk to be part of those few who will notice it ?
