Backer #441: Initial 8K-X impressions (Milopapa)

More seriously, if we let out of consideration the “Pimax Experience” and after sale service, I still wonder what is the number one factor that let you prefer low FOV like the G2 vs the low SDE, good resolution, large FOV 8K-X.

If the picture of his 8KX was hardly better than that of his 8K+, I do understand it - I liked Assetto Corsa on the Index more than on Seb’s 8K+ because the far sight in his 8K+ was strangely blurred.

I just wonder if this is the same what others who have the final versions see too - if not, then his Pimax units or setup are likely not working properly. In which case the conclusion is obvious, but should not be taken as meaningful evidence for a purchase decision of another user now.

Of course Pimax headsets have these other issues of not being simple to use and at risk of needing a healthy dose of tinkering to get certain games to work properly. That certainly will remain as long as Sweviver doesn‘t do his miracle of releasing a software which truly automates all these efforts. Would be truly grand if he can pull it off, but I will wait to see it work just before I open a bottle of champaigne…

It is pretty easy to say. With the 8KX, it feels like I am looking INTO a beautiful, high-res VR world. With the G2, I feel I am IN that high-res VR world. Now that is a pretty significant difference. Immersion! As I had mentioned before, for the 8KX, it feels something is “off”, the optics are just not perfect. I have to concentrate to focus on something in front of me, like the gloves in Alyx for example. For the G2, I don’t feel like I have to actively concentrate or put in any effort, it is just right, just like I was looking at something in the real world. Reasons are likely that displays are not canted, better lenses, better colors, no distortion.

Do the other canted wide view headsets like starvr have the same issue or specific to your pre production 8kx ?
maybe it needs some fine tuning or not enough overlap

edit

if you hold a pencil between your eyes along your nose , the images are the same but the reduced overlap does seen odd

It is not specific to this preproduction 8KX, even though that would be the most convenient answer. :slight_smile: I have the same feeling with the final 8K Plus for example. Anyways, I am not here to spoil anyone’s pleasant anticipation of their 8KX, and I do think people can get used to those optical imperfections. Our brain is just so incredible at these kind of things. For me though, having all the options available, it is tough to go back and forth from devices without optical problems to devices with optical imperfections.

I read somewhere that the stereo overlap was a bit less

True. I think the problem might be that the canted lenses make the very center of the view slightly out-of-focus (compared to the vision just outside of the central area). By “the very center of the view”, I mean the central “fused vision” area directly straight ahead, where we expect the sharpest vision. Personally, this doesn’t bother me, but sometimes I find myself turning my head slightly to bring centrally located text into sharper focus.

The problem is, the same could be said about the narrow FoV. Yes, once you use it on a daily basis you will get used to it again but it bothers you nevertheless when you switch between wide and narrow FoV headsets.

I guess at the end it is a matter of personal preferences, as often with VR headset comparisons & specs, and one should be careful to put all weight on any given reviewer‘s opinions unless over time you have recognized that they match your experiences (especially when directly comparing different headsets at the same occasion).

This is a factor the reviewers hardly can be blamed for, yet at the same time the viewers should be careful not to translate journalist/Youtuber X says this one is the best means it will be the best for me too. I get the impression that some users seem to think if reviewer X declares headset Y to be better than headset Z, they are convinced that headset Z is no longer good for them, like at all. In reality there is still a good chance that they would like headset Z even better than headset Y if they had the chance to try it for themselves. At least with headsets relatively similar, not talking of comparing the og Vive to the 8KX or G2.

I mainly play FPS’s, so not being able to aim because its all blurry is a major issue

Just found this.

Looks great , I’m sure everyone can all get used to a bit less binocular overlap in no time

Me too, I wouldn’t use the 5k+ for fps I use the vive pro every time

I feel way more immersed in the StarVR One than on my Index. StarVR did something right. Custom made lenses using 4 seperate panels. And I actually don’t feel any eye strain in the headset, whereas I feel some eye strain on my Index. And it is the lightest most comfortable headset I’ve ever used. It’s easy to forget I’m wearing one.

So I think canted displays can be immersive if done right and it seems like Pimax cut corners on their lense design to lower the price at the expense of immersion.

I didn’t say “it’s all blurry”. I said it’s slightly out-of-focus. I can barely see that it’s not quite as crisp as the area towards the center of the panel. The only time I (sometimes) notice this is when I’m trying to read very small text.

I’m speaking from my experience, playing fps’s on a 5k+ was not doable because aiming with a scope gave me a headache in 3 seconds

Are you talking about with link?

i’m impressed with the quest screen, i remember think how sharp everything looked in robo recall.

Vive has the worst SDE of any headset i’ve used (and thats alot) but it’s weird im not bothered by it. I’m one of those guys that can’t stand those interpolation or bilinear filtering when playing old school emulators.

I like the crispness of seeing pixels

indeed vive OG has worst SDE of any HMDs I ever used, although Vive Pro IMO has a bit better SDE than Quest & screen overall is better, but they quite close to each other, although Vive Pro has terrible sweetspot & lenses, but the immerse feeling (the 3D depth) is far better than on Quest & slightly better than on Idex.

I did gearvr lense mod & I think it even decreased SDE but eat some FOV & somehow affected the picture in terms of geometry (I used most recent afapters though).

But IMO at the time being Vive Pro has the best screen of all HMDs in the consumer market, I wish I could find a company who can do the same Vive Pro lenses but without clarity issues it would be total blast.

I did the lens mod too, what you gain in quality you lose in mild distortion / pupil swim

Hello !

I have been piloting in simulation for 20 years and have been following this 8kx discussion from the start!
I would like to thank’s @Milopapa for his big test! :innocent:
Since the time that I have been driving in karting and in car simulation I have been interested in VR helmets in 2012!
Oculus Dk1 / 2 / Htc Vive / Oculus Cv1 / Pimax 5k + and now I’m waiting for my 8kx! Me what I want for 1500 € is to have a 1440p image in visual quality finally!
My 4k / 50 inch Lcd / Panasonic AX800E tri screen in car simulation on iracing gives me real visual quality, This is the holy grail for me and my team on iracing the 4k!
A 4k image is pure happiness and we will see what this 8kx pimax is worth on races of 2/6/12 / 24Hours on iracing?
Because for the moment since 2012 no VR headset has more visual quality, mush of pixels with an image worthy of PC screens from the 2000s in 720p no more no less!
I am impatiently awaiting my 8kx pre-ordered on October 31st 2019 to see if it is great or if it will join my other vr headphones in the dust?

————————————
In my team of 8 pilots on iracing we even have a French karting champion, and many have VR helmets, of any brand from Cv1 to index, including Hp G1 / Pimax 5k +!
None suit us in terms of image quality yet we love Vr 100%!
Team pilots have ordered HP G2s, I am the only one to have ordered a Pimax 8kx wrongly or rightly!
Our discussion in my team in the fall in Vr:
8Kx Vs HP G2:

-What is the best of the 2 for iracing?

  • Or then none of the 2 is suitable for simulation with our 4k quality criteria in pro pilots on iracing ??

Wait and See but Quick quick my 8kX in france :innocent:

I thank Sebastian from @Mrtv for all his videos for the vr and for the future of his youtube channel!
Not easy to be a youtubeMan in Vr :innocent:

apluhhssssss

I hope you find your 8KX to be worth the wait and that your teammates will be envious of your new headset. :slight_smile:
