The best example I can give is in astronomy if you use cheap oculars the sweet spot will be very narrow and only a few degree wide from the central axis of the optical apparatus
The sweet spot is not directly related to the sharpness across the field of view itās simply the localization in space of your eyes vs the lens where the displayed images have the best quality possible for a given headset within a acceptable margin toward translation in the X/Y axis of the observer for a given best Z distance.
Unless you have extremely big or small eyes it should not change much. Itās more a property of the optical system. For the same sweet spot size perceived distortion/sharpness could vary from person to person this could influence what is seen as an acceptable sweep spot size but the optical properties wonāt changes
This unfortunately is the feeling I share too - there whole season concept seems to be being dialled back year after year, and I am convinced the next big update, now slated to cme end of next year, is the last substantial addition to ED. After that they will at most provide updates & big fixes to secure compability with new hardware & software. I guess they donāt like the business model because continuously paying for servers while the customers only paid once at the purchase of the game is not ideal. They had the brightidea to push paid seasons but only once did so with the horizons season, and the next one will be the second and last paid season it seems.
Itās a pity but not much we can do. Hopefully others like SC will step in with substantial game play and simulation - I donāt really care about the action-packed Eve like combat simulators, combat is not my primary, not even secondary motivation to play the gameā¦
Heh, replying to myself, with a silly little thought experiment.
So, say Robin has acquired myopiaā¦ That does not strike me as a far fetch - he comes across as somebody who have most likely worked behind a computer monitor most of his career, and he does wear glasses ā heck, increase in cases of near-sightedness has supposedly also been markedly higher in China over time, than elsewhere in the world.
So carry on the loose reasoning from that, and figure that he has designed the Pimax lenses tailored to his own eyes - maybe his engineering team are all similarly afflicted - we are all nerds here, after all. :7
One could easily imagine that should produce something much like what we seem to be having here:
For people with elongated eyeballs, after years of office work; The view is perfectly fine and sharp, falling focussed onto their retinas for imagery from a long radius away from the centre of the lens.
ā¦but for everybody else, who still have fairly round eyeballs; Theyād still have a sharp image in the exact centre, but then, outwards from that spot, the light would be focussed to a curving plane that lies a bit behind their retinas, producing just the severe falloff in focus many of us seeā¦
Yeah indeed, and Iāve been an Elite fan since the BBC days. Donāt want to go too far off topic but now I feel a tortoise and hare analogy makes sense. SC 3.8 released last night and the additional thought that has gone into the systems, from dynamic weather to law to mining (and I wouldnāt normally bother mining in ED) surpasses Eliteās, it can deliver gameplay we endlessly waited on but never received from FDev.
I just hope the tortoise doesnāt run out of puff before the finish line
Since the latest Unreal Engine doesnāt require PP, that should mean that more and more upcoming new games developed with 4.18 shouldnāt require it, right? Or is it something developers still have to decide to enable?
Last night, I paid particular attention to how large the in-focus area was.
From the center to the top/bottom ~80% is crisp enough to read text in Elite D and from the center to the outer edge is about 70% (in Normal FOV). In the central area everything is super-crisp, so that the SDE is annoyingly visible, but closer to the 70-80% edge of the sweet spot, the SDE is no longer visible. Tiny text is a bit hard to read in the periphery, but the medium-sized text, like the time, is quite readable until it gets close to the edge of the lenses.
Hereās hoping to get results like yourās, in the 8kX. :7
ā¦although if my prior experience was all about my 5k+ having been a dud (one of many, many, judging by what others have to say), I feel kind of guilty now, for selling it on ā I really hope the buyer feels he got his moneyās worthā¦
Thank you Sweviver for all your updates and enthusiasm to the Pimax Kickstarter project, including 8K-X. Itās good to have these threads posted to keep our interest and hope alive.
I want to throw in another aspect which imho differentiates the pimax from most other hms regarding the perceived distortions: the lenses move over the stationary panels. The panels are so massive that pimax decided to not let them move with the lenses when dialing in the ipd.
So the distortion profile must Include one more factor: the position of the screens relative to the lens.
And my terribly awful experience with the p4k in that regard tells me that there is a good chance that pimaxes of the earlier generation did have more often not properly aligned s creens which is the reason for the many different experiences with p5k/8ks.
I recall sweviver stating a few month ago that the distortion was improved by more properly testing the assembly of the screens (if they are in correct position).
I do hope that Pimax is improving their assembling even more and that soon via eyetracking pitools is using the correct information Of the position of our eyeballs to correct for all of that necessary for us to have an optically correct view of the virtual worlds.
I want to add: thank you so much @SweViver for the information you provide. You rock!
I do know how you must feel about others misinterpreting your info given. If on purpose or not does not matter at all. I am an expert (worldchampion) and had to learn my lessons in communicating with non-experts or hobbyists. It is not easy to accept that you can not explain things to everyone - despite you would love to because you are driven by passion
This is me. Had glasses all my life. Every time my prescription changed, Iād have a period of adjustment where there was warping and distortion at the peripheral of my vision, but my brain adapted to it, and it āwent awayā so to speak. Even now, where the lenses cut off (I donāt where those huge 1980ās glasses anymore, lol) there is a very sharp change in magnification with some distortion, and it doesnāt bother me.
This is why Iām not worried about distortion (so long as it isnāt at carnival funhouse levels of course), I know my brain will get used to it and then filter it out.
I do want to get laser surgery though, Iād heard life without glasses is amazing, and Iād love to experience that!
I wear progressive multifocal lenses āno-line bifocalsā, thatās a huge adjustment to get used to. The last time I switched to a new prescription, it took me 3 days to adjust. Now I can switch between no glasses, my new prescription, and my old glasses almost instantly.
The thing is, I didnāt notice any distortion when I first wore my 8K. There was no adjustment period, so I think that means it was just like wearing no glasses (at least for me).
The new Pimax headset and that little room for glasses made me get laser surgery some months ago.
Loving life without glasses for sure but it did make my vision close by less sharp. When youāre near sighted you actually see better close by than someone with 2020 vision. Laser took that advantage away unfortunately. I used to be able to see the pixels on my smartphone but not anymore. Canāt focus on my kidās face two centimeter from mine either. I was surprised all this would be so noticeable.
Hi Pimel
Trust med when I say this, your vision will change over the next 2 years, things will become clearer again. I had Relex Smile dine approx 4 years ago, and my sight āsettled inā agter approx 2 1/2 years.
I understand the argument but I think itās wrong one, VR headsets are for most part amusement and optional usage device. we should not have to train our brain or our vision muscle to use them. This in the long term could be detrimental to our vision health. So manufactures should provide the less artifact or distortion prone headsets possible.
So the comparison with glasses canāt stand here, but itās true that any optical devices will have some distortion toward the edges one of the reasons among many others that some manufactures decided not to build large FOV headsetsā¦
The same could have been argued about SDE in first gen VR headsets. Kind of a kin to sitting too close to the TV and having low Res causing other potential sight issues due to Vergence conflict.
In this regard it could be said headsets with HP Reverb resolution as min is finally bringing headsets more fit for use.
Huh, interesting! Thankfully Iām farsighted, so I donāt have any close vision to lose, its all garbage. It can only improve things from where Iām at, lol.
1 Year and might have one Eye re lasered, still think itās worth it for my experience and a bit hassle freeness in VR comes along with it.
Damn now we are at a health progress - sorry, hope to hear some Last updates soon and hope all have time to enjoy the holidays.
