I don’t think the brain does distortion correction. I have the Oculus Rift for 2.5 years and I can still see the world skew distortion if the headset is not in the correct position. With the Rift, that distortion is easily eliminated by adjusting the position up or down the face.

Update to my previous comments of blurring on inner lower edge
Ok so a few days ago i reported bad blurring on lower inner edge of lenses and one eye always seeming blurry .After goin to an eye clinic this morning I found out for the last 2 years ive been playing with the wrong ipd ,given to me by my optician(stevie wonder). It seems they were 5 mm out,having retried the 5k with correct ipd i can confirm its epic,the clarity in games is amazing no longer any blurring or milky spots in vision the colours still need calibrating but in most games there fine.I no longer notice the stereo overlap no w the ipd is correct,strangley enough ive not noticed any difference in the rift even though before my ipd was 5mm out hence not going that low on the pimax ipd before and noticing how good it looks when set up correctly.gotta say pimax im impressed .

Yeh, I agree with the explanation of @flobv.
For about 10 days when I used 8k, it was this distortion that I was most upset with.
I could find this distortion on my Daydream headset.
In comparison to the Daydream headset,
Yes, there was distortion when my eyes were placed above or below the center of the lens.
As a result of further observations,
The Pimax 8k has a very small zone with no distortion in the center of the lens and I found it difficult to keep the center alignment while using 8k with the head strap.
I had to constantly care about the alignment of the eyes and the center while using 8k for about 10 days and eventually I was tired and sold out.
The Pimax 8K developers doesn’t seem to have analyzed Oculus Rift and Go at all.

Well I think it’s mainly a problem with wide FoV. The wider the FoV, the more your iris will move and that’s the problem: https://community.openmr.ai/t/110-degrees-fov-stretched-to-200-degrees-edit-all-the-games-render-in-a-native-wide-fov-through-the-engine/3024/155

Ergonomic design for center alignment and retention of eye and lens…
Sadly, they don’t seem to have considered at all.
Well if an iris would always stay at the same position, you could solve the distortion by just generating 1 optimal distortion profile for that iris position. But once you’d start moving your irises you’d get a very weird distortion effect. So I think Pimax kind of tried to find the ‘middle ground’, we now see distortion all the time but not so extreme like you’d see it if you’d move your irises in that other scenario.
Anyway that’s my idea on it

Brain will do odd things. Maybe not broad correction. But things like getting used to sde to ignore or it’s own interpolation. Just depends on the individual.

I found horizontally sweet spot is large. But vertically is narrower & til one gets used to how to place can be troublesome. Though my poor man’s deluxe headmount does the trick well.

That I believe is more an issue of the strap head mount.

Sure, Heliosurge. I think Pimax should have a bit more thought about the design of head straps with earphones.
The Windows MR style will probably still cause the same problem. So I think Pimax should have to pursue the Vive DAS style. At least if they consider the center alignment of the eyes and the lens, the comfort of wearing the headset, and the ergonomics of wearing the headset…

Agreed. Now if you look at the pic of the deluxe head mount it seems to be using a similar design of the DAS. I think this is why we are seeing changes in the head strap in different batches. It’s where it’s hard to have a one fits all design (except with spandex). Remember the p4k complaints regarding noses.

Though I don’t have a pimax headset, but my pledge is still alive.
So I will watch Pimax until the 8K X is released.
Anyway,
Now, we will be using 5G high speed communication service soon. As you know, Korea has already started.
I think these changes will break the boundaries between PC and mobile. So now I am focusing my attention on all-in-one VR and streaming services.

sjefdeklerk,
I wonder if this effect you are experiencing using the SteamVR room is a result of using this particular room. I still have not tried the test you suggested earlier since I do not use the beta. I only say this because just this morning another fellow on the reddit forum reported the same experience as you have reported and he concluded that this SteamVR room was the only place where he experienced this and did not experience it once he entered a game. If its only SteamVr beta room doing this It could be just the way the room is set up. Have you tested it recently the changes and updates seem to be happening frequently.

No, it happens in any game. I just mentioned the SteamVR (non beta) room since everybody has that.

No worries, but am sorry to here that has been your experience.

So bizarre I don’t see that stuff at all. About a 60 degree circle sweet spot is pin point clear in the center. Outside of that I see no distortions or whatever it is you seem to be referring to. It looks slightly out of focus outside the sweetspot but I don’t see any distortions at all unless I rotate my eyes to the very edges then on large FoV I see some but I find it bizarre that stuff that far outside your vision could be distracting.

Yeah, my experience sounds about like yours. I only have distortion and blurring at the far edges. Really strange how some people are seeing things so different.

As I said in the other topic, it’s due to the fault of rigid headstrap. The distance from the eyes to the lens, and the HMd must lay over the face, without pressure.
If we were able to adjust this distance, we wouldn’t have this problem at all.

Wonder if this could be used to fix distortion
