Is the 3D Stereoscopy improved for the 8KX?

I love my 8K, it’s still what I consider to be one of the best commercially available consumer headset. It’s biggest competition being the 5K+ (yes i know the 8K is no longer sold).

Anyways, my minor complaint is that the stereoscopy could be better. Once objects get to a certain distance they all start to appear as 2D. Has the 8KX made any improvements in that area?


I don’t think so. Pimax is using the same lens (but with an improved distortion profile).

You might want to try decreasing the IPD, in either/both hardware and/or software. I decreased my hardware IPD by 2 mm and saw a significant improvement in the 3D effect.



Personally, even out to almost 1km effective distance, with somewhat natural objects/scenery, in flight sim, with a 5k+, things still seem to have a bit of 3D parallax.

Obviously, the 8kX will improve on this, but since I already had a good sense of depth, I don’t really notice.

What I do notice is the overwhelmingly better clarity, lack of haze, and per-puxel color accuracy that comes with higher resolution.


Can you give something a try for me? When I’m in Google Earth VR (almost 4 years and it’s still my favorite experience) and I’m hovering a few thousand feet above land, when I switch to “fixed human scale” I immediately lose all sense of depth and 3D stereoscopy. That’s where I notice it the most. Could you give that a try and let me know what your experience is? I consider myself a pretty good judge of depth as well, so I’m curious what you say.

Thank you i will give decreasing IPD a try. Btw, what’s the difference between software and hardware IPD adjustment? The hardware adjustment moves with the lens and the software doesn’t?

Realistic depth is much more subtle than the exaggerated mode offered by Google Earth VR. That said, it is entirely possible that sufficiently far off objects in Google Earth, or 3D buildings, are rendered as a flat texture in ‘fixed human scale’ for performance and coding simplicity reasons.

If you want to test Sterogr3aphic overlap. I think @risa2000 hmdq might provide this info. It does report what is rendered for requested FoV.

There is an IPD fix that some people are doing themselves. Apparently, that is helping with Eyestrain and also improving 3D stereo perception

Yes, hardware IPD moves the lenses.

Use the hardware IPD adjustment first. Then, if you are at the end of the range ( < 60 mm or > 72 mm), use the software IPD to extend the range. Some people use software IPD to “fine tune” the hardware IPD.


My hardware IPD was at the end of the range, then tweaking the software IPD helped a lot :+1:

  1. Stopped one eye being slightly blurry with the slightest headset position change
  2. Reduced eye strain so I can play in VR for longer
  3. Improved the 3D stereoscopy further

There should be, mostly because there are more pixels allowing for more parallax between each eye, and more levels of depth.

I’ve noticed greater depth reproduction in the 5k+ vs the vive.

However, people can’t perceive depth past a certain distance, IPD being the limiting factor. If you had two periscopes and a 30’ wide ipd, you’d see in hyperstereo and could see clouds in 3D!


My IPD is 68.5. I used to turn the physical IP all the way down then use the software offset to get it back up to 68.5. I felt like this increased the stereo overlap tremendously. The software offset doesn’t seem to work the same since a few updates ago and I can’t do this anymore.
