That not sure save editting one of the steamvr settings file. You might not perceive immediate effect. Only active method have seen is fpsvr.
What I would suggest adjust the Steamvr setting as per fpsvr and take a 15 to 30m break between adjustments.
Myself I don’t perceive much changes adjusting hardware ipd so unfortunately can’t guide better save going by the fb post and what others have said.
Speaking of focus, my IPD is about 59 or 60 like yours. I can tell you that on my 8KX I was never able to get a good clear, in focus, can see the individual pixels, type of image no matter what my software IPD setting was until I performed the Extreme IPD mod on the 8KX where you basically carve out all the plastic inside the HMD to allow the actual lenses to move closer together.
To verify I could get a more “in focus” image before performing this crazy extreme modification, first I set the mechanical IPD as low as it would go to meet my IPD, then I held the HMD to my face right in the center, at this time I had a decent looking images in both eyes focus wise, but, then I would move the HMD just slightly to the left, as I moved it slightly to the left, my left eye’s image would come into a crystal clear focus, telling me that the left lens need to come more to the right, then repeat this procedure but move the HMD slightly to the right and the image in my right eye would come into a clear sharp focus. So this confirmed that if left lens was moved to the right and the right lens moves to the left, I would have a clear in focus image. So I started the Extreme mod and Ill be damned it worked!
Now both eyes can see a perfectly clear and in focus image. Now heres the issue. I STILL cannot get rid of that dreaded “eye strain”. Its like if I set the soft IPD in Pitool to make everything in the foreground comfortable to my eyes then everything in the background makes my eyes strain and just the same if I set the soft ipd so that everything in the background looks good with no to little eye strain then everything up close give me the strain. Very frustrating!!
That’s what I suspected…that if your real IPD is around 60mm or less…then the mechanical lenses need to be as close as possible. And since it cannot be done (unless you mod it), then you’re stuck with these overlapping ripples effects that the lenses created. Software would not have solved this.
I couldn’t understand why Pimax couldn’t see this as an issue unless, UNLESS they didn’t have enough feedbacks. Getting feedbacks from the shows that they did is not good enough because some of these issues are not apparent until you use it longer. It is similar situation with the strap or comfort kit. How can you say that the headset sitting on your head is comfortable without letting users pull the strap all the way to the lower part of your head? Once again, these kind of issues make you question if they even getting any feedback at all? If you go around asking 10 people how comfortable is the headset after using them for (not just days), but a month or two, then that’s real feedbacks…otherwise it’s not real feedbacks but just initial impression which is not good enough to turn into real products. Now you’re coming out with headset that makes people want to modify or add stuffs because obviously they’re not happy with it.
Yeah, no question I am having the exact issue you were having.
Setting the software IPD to 57 is doing well, but I do see that my vision is still slightly more clear when I look slightly towards the center of each lens.
I just can’t bring up the guts to do an autopsy on the HMD…
I hope Pimax can address this in the future. If we are to have 8K per eye models and 16K per eye models, it’s only that this issue will stand out even more.
I started a couple of threads here regarding eye strain when the 8K and 5K+ were introduced. There were hundreds of replies, even PimasUSA Kevin responded but not in a constructive way, instead he said this was not an issue, was anecdotal and said out of the 1000 replies there was only a dozen with the issue, lol.
Pimax knows about the eye strain issue, now maybe they werent as aware about it until the release of the 8K and 5K+, but they knew it was a problem and have tried with the IPD offsets in Pitool, now with the Pimax Experience they will be adding some kind of IPD adjustment there too. But IMO they already had a shell for the 8K+ and 8KX and were not going to retool from the 8K and 5K+
Imho when the extreme ipd mod was introduced all they needed to was implement it with either a pulse encoder(easy to calibrate if needed) or a pot with greater range.
Yes and they should have implemented the Extreme mod to production units
I have my 8k+ now for three days. I have a IPD of 65. After countless atemps, I cut a cardbord-strip 65 mm long for measurement lens to lens. I had to go all the way to the smallest possible physical distance in the HMD to get 65. Its perfect now for me. No more eyestrain. Values in the HMD are way off now though. I cant get, how something that important is not clearly communicated.
I think that because the displays in the 8KX are smaller than the 5k+ and 8k’s displays, there is some problems with eye strain as a result of the 8kx having smaller displays whilst the optics remained unmodified.
I remember reading some discussion in the last few months about the fact that Pimax reduced the display size but didn’t move the displays further back into the display, and as a result people who don’t have sweet spot issues on the 5k+ have sweet spot issues on the 8kx.
Interesting though reading your post where you said you had those problems on the 5k+ and not on the 8kx, that just makes it all the more confusing.
Can you tell me which problems you are referring to?
And maybe thats why I had a crisp clear image on the 8K and 5K+ but not on the 8KX
