Matteo311 review - Pimax 8KX VS Valve Index

Pimax Hardware P2: 8kX
121

Now you are reprinting me out of context right below the original quote. What are you doing? I wrote nonexistent support, not nonexistent consumers.

122

Which is not out of context. There is consumers and there is support in programs and hardware.

For the most part I ve
been lucky that pimax 8kx has been solid for me. Original Vive had it’s moments…as well 5k+… No headset is perfect… just looking on reddit …even reverb g2 has issues .

I guess index might be most user friendly. Point is customer service for most of these headsets aren’t great from what I ve read .Pimax not good either from being on here as long as I have.

Just now I had time to watch the review, sums up my thoughts exactly.
Whether the 8k-X is technically advanced in some aspects, it’s not a newbie or a casual gamer headset.

Lol. TLDW

is what most people would say if all VR journalism was like those guys.

Although we have so many casual VR news channels now I wouldn’t complain if GN started covering VR with the same level of detail.

You’re right about this. I hate BenPlaysVR’s pimax reviews and reviewers who just throw the headset on and say "too much distortion…oh well this product must be crap 2/10.

Its the equivalent of a games journalist reviewing a game but only playing the intro.

We need more ACG level reviews of VR hardware.

not sure what you do to eilminate those, but whatever I tried to do I see quite noticable geometry distortions, I note them even in potato mode, it’s fine in terms of sweetspot, I see almost edge to edge clear & sweetspot is very find, I can decrease distorations to some degree, but I don’t like them at all, it’s one of the biggest issues in the Pimax HMDs for me. I don’t see them if I looks straight & FOV is great but I used not only to see straight on all potato HMDs & I don’t see any geometry distortions there. I really don’t like that. Its big imerrsion killer for me. While some use cases in HMD feel & play fine. But I can’t use it due to another couple of issues as daily driver:

  1. geometry distorsion
  2. poor performance (it’s ok for some titles) but I just can’t justify this when other brands have so polished reprojection & I even sometimes don’t notice reprojection at all & can play dirt rally 2.0 on all max settings on 200% super sampling while I never will get even close on Pimax with this level of details & antialiasing, if I low settings it also pretty smooth on 5k+ but I miss all the graphic then (3090 user here).
    To be fair it’s not that bad, but even if we compare the same or similar FOV (potato) with other HMD the performance anyway worse coz it’s additional layer of soft & it’s not perfect, I remember that nasty GPU utilization issues on top of it, nowadays it’s better but still not on par.

I tried to use it couple of months & indeed distortions start to feel less obvious but anyway I still notice them. Not sure if that changed on 8KX as they readjusted magnification but I guess even if it is then it was not significantly.

Pimax often distracts by some or another reason & eats VR gameplay time, while on other HMDs you just completely forgot about those issues & instead focus on content & other things. They close to have more or less polished product & it’s already usable. But it’s a big bunch of problems. It’s like a car that was designed wrong & every 100 km you need to stop, check oil, fix something that broke etc. But it works though & has a nice look & some specs are great but not as the whole package.

Distortions in the Pimax Vision 8kX in potato mode cannot be worse than other headsets, unless your IPD is well outside the hardware accommodated range. That is the point.

of course it can not be, I just have eaten some mushrooms & got hallucinations (my IPD is 64-66/68.5)

the forum is full of that denial $hit, I won’t go in arguing here. Pimax distortions is the most famous Pimax flaw for years. Of course it can not be the case, it’s just wrong HMD usage. We don’t know how to use this well designed piece of optic hardware.

I might have actually agreed with you at any FOV other than potato.

132

on potato it’s much less pronounced, but if you stay at room corner or have another well defined geometry object with straight corners, it’s quite easily to spot on the screen edges in potato, it’s the most distract fee experience, but it’s still there. At least I see them if I use periphery part of screen, i.e. looking aside to check menus etc & rotating head during this aside lookup, on static it’s much less pronounced.

Well we know Matteo didn’t do one of those kinds of reviews. His was honest and on point and not truly negative as he cited the common issues that are widely known. He never said it was crap.

Some of the issues experienced could have been remedied with simple sharing info without needing a 1 on 1 session with support.

Well they were not there in the p1 series as it was well designed Aspherical lenses. But yes the geo distortions and peripheral is well known in the p2 wfov headsets.

Potato is less pronounced as it is within the Yoke of the egg lenses vs transition area to the flat or white of the fried egg.

Absolute sadness. Pimax should be making sure their drivers for the 8K-X inbuilt Microphone works with Windows without all this merry-go-round extra setups.

I ran some testing the other night and to be honest, in its current default install state - the inbuilt 8K-X microphone is pathetic.

As for visuals - 8K-X is great. Key is working with SS settings. Some suck - others don’t.
If it is not fitting well with the native pixel output of the VR’s display panels - then even at high SS settings - things can appear blurry and not clear.

Time and testing help but sticking to SteamVR ratios of 50%, 100% 200% helps along with then using PiTool / Pimax Experience to set the Video Render Setting from 0.5 through to 2.

I find 1, 1.25 and 1.75 seem to work well for PiTool / Experience Render settings and the above SteamVR SS % settings.

Y.M.M.V.

when do they wake up about this issue?
on such a expensive device, great audio(mic and speakers) is a must!

But they are. I see them too in potato mode. Not sure why you’re denying this

It’s really really sad. When the guy from StarVR came to this forum and offered his help, Pimax refused and claimed the distortions were already solved … Sigh.

@mirage335 I think what you missed is that the inner part of the lenses have distortion too. Set your Fov to potato, close one eye (!!), look at and focus on some vertical straight object while moving your head horizontally left to right. In the innner, maybe 8% of the FoV you’ll see the objects bend like rubber. I don’t see that with my index for example. Yes, the outer part of the lens distortion is mostly gone at potato, but the inner part of course is not.

For what it’s worth, I agree with what some others have said and that you actually somewhat can get used to the pimax distortion, honestly to the point where it’s not my biggest issue anymore. But still, it’s there and it would be much better without it. But Pimax rather solves it instead of denying

@Neoskynet mentioned this kind of desensitization with “getting accustomed” to. Optics issues in projection. It is also the same idea that was used on SDE in gen1 headsets along with getting your vr legs(gaining tolerance for vrsick).

Simple truth with any vr headset (just about) one will become desensitized to the flaws with more use.

140

Well this isn’t true that every headset has glaring flaws you need to get accustomed to actually, StarVR has wide fov without any distortion, and as it has been said Pimax chose not to receive their help. Yes most headsets have some small flaws but Pimax wfov headsets have had a lot.

I think what’s sad is not just has there been a denial about issues such as distortion, eyestrain, IPD issues etc from Pimax, but Pimax has flat out stonewalled discussion on these issues, deleted topics of discussion on these issues and banned people for talking about it in the past who were requesting Pimax to talk about it or to look into these things in a supportive way.

I don’t really trust anything Pimax says anymore, only their actions and what’s in their next headset will speak as to whether they are serious about fixing issues with their headsets, such as

  1. fixing geometry issues

  2. 3d overlap and lack of depth issues

  3. by including bluetooth with headsets

  4. not using s*** quality microphones

  5. using better optics

  6. including the fiber optic cable with the headsets

  7. including proximity sensors to the headsets

  8. funding Pimax experience with actual money

  9. Including DMAS with high end headsets like 8kx, not tinny SMAS sound.

  10. fixing the blue housings with impervious level housing so they don’t crack anymore

  1. and not just taping the tracking photodiodes to the interior of the headsets

Most of those issues are pretty low quality implementations to be included in a high quality headset that sells for so much like the 8KX.

If they don’t have these things in the next few years, I’ll just save and buy a competitor headset like StarVR or the half dome with 150 fov ¯ \ _ (ツ) _ / ¯
