Half-Life: Alyx on 8K X

@NoamLoop
The audio of the DAS does not impress me, but to be honest no vr headset does. The index is the best as far as sound quality , but in my opinion leaves a lot to be desired. I have an Astro A40 headset and it’s miles ahead of the Index. Actually the Astro A40 and the 8k+ with comfort kit and stap is more comfortable then my index for me. I’m not 100% sure I will want to use the mas when I receive it! Lol

Though I probably will for ease of use and ease of adjustment for when someone else uses it.

Artisan has FoV 170° Little less than normal in 8KX …much bigger than small in 8KX and others Pimax

Hi. Just want to know if the distortions are still better than 5k+? I saw a video that vou sad that the distortion was improved but its seems in this video that is not. And about the world scale of Alyx in 8kx, its off? to big or to small? I hope its not like borderlands vr.

Certainly there is also the brand effect. But let’s take your example Xiaomi Android vs Apple.

Xiaomi gives a product with superior technical characteristics at a clearly lower price than Apple. What does Pimax do instead?

Let’s take a product of easily comparable DAS Vive Vs. MAS Pimax. At a higher price $ 120 + tax + shipping. You are given less! Sound system significantly worse than Vive not to mention Valve Index.

Same thing we can say even about Artisan 440+ taxes + shipping WITHOUT MAS and Audio … So Pimax is not copying the success stories of Chinese manufacturers with Android … it makes commercial policies as if it were Apple being instead a Chinese startup on Android …

Sebastian @mixedrealityTV, reading your impressions about the distortion on the 8KX, I suspect you have (by mistake) received an 8KX unit with a firmware that requires a json file for distortion correction improvement. This was the case we had with a couple of 8KX units right before CES, which we ended up not using.

Now, this is possible to fix easily, and I want to guide you how to correct your distortion. I would appreciate if you could report the results after doing this:

  1. Go into filder “C:\Program Files\Pimax\Runtime”

  2. Create a new folder there, name it “hmd_confs”

  3. Copy this file into the new folder (P2_8K_formal_N.json):
    8KX Json file for V4 - Google Drive

  4. Restart the Service in PiTool, or reboot your PC.

  5. Turn on Normal or Large FOV and report back.

I suspect this will fix your issue with distortion.

We might also try with another firmware if this doesn’t help, but Im pretty sure the json file should do it.

That raises hope. The big FoV is one of the big selling points, so being able to play with at least normal FoV would be important.
But guys, sending out units to influencers without any quality control - even for a “preview unit”… Pimax is still Pimax’ worst enemy…

I have difficulty in trusting the fact the 8KX was laggy or distorted when playing HL:A. I’m not saying Seb’s unit didn’t have the issue. It’s just that after thoroughly testing the 8KX in Orlando and not any seeing issues in multiple games, including Valve’s own Lab, I just don’t think something was set right.

I have both Index and 8K+. I packed up Index when 8K+ arrived several months ago. Now I get Index out to try Alyx on it as this is the “official” headset for it. I immediately noticed how SDE is more obvious and effective resolution is lower on Index. Index also has some sutble lines when I move my head, a phenomenon that also exists on Pimax 5K+, but 8K+ does not have these lines that look like little interference. So 8K+ not only looks more high resolution, less SDE, but also has a cleaner background. The image of 8K+ does have a “soft” feel, which must be cause by upsampling, and I believe 8KX won’t have this “softness”. Still this “softness” is not annoying at all and the image is clean.

Even though 8K+ has quite some advantage over Index, I am still using Index to play Alyx. Somehow I feel this is the right way…:slight_smile: and this is more or less a way to show my respect to Valve. Please be noted Index is really a premium product and the image quality and even FOV stand quite well against 8K+. It also have some edge over 8K+. It’s more comfortable to wear. The FOV, though smaller, has more consistent image quality across the whole view. It also has much better sound, which is also very important for me. I might change back to 8K+ somewhere along my play, but I am not sure when it will be.

Hi @NoamLoop,

it will also depend on the game you play. If you are playing 10 minutes of Aerofly FS2 without really moving your head, you will more likely just experience the beautiful picture and the clarity of the gauges that will blow you away in that moment. You might slowly turn your head to peak out of the window, but that’s it for your head movements. And what you see outside is quite a fair amount of uniform color sky.

Now contrast this with the frantic head movements of a game like Alyx and having hours and hours to A/B compare with all other headsets.

That makes a huge difference.

What really excites me is how Pimax have managed to nearly eradicate all of the distortion with the Artisan.

Bye, Sebastian

I have no doubt that with 120fps it looks better, but you can always play with the 8KX at 120fps as well.
But it’s strange that the Artisan, unless the size of the screens or the distance to the lenses changes or something else, looks better (with less distortions) than with the Pimax 8KX, it wouldn’t make sense. The only explanation, if not, is that the software or hardware is wrong.
Have you had a chance to try the solution SweViver was talking about?
I’m sure there are many of us who are interested.

If you are 8n for good audio… I use an EVGA Nu or a good soundblaster like the AE 9. Get some GSP 600 from sennheiser or the Beyer dynamic.
Then you don’t ec
Ven care for inboard or on HMD sound. A simple quality audio cable that wraps around the HMD Cable and done.

It does not look better on the Artisan. Again, the picture quality on the 8K X is excellent and better than on all the other headsets. Also the performance of the game on the 8K X is fine. It is about distortions that are less on the Artisan. Also as compared to 5K Plus. So everything is perfectly fine with the 8K X. It does not have more distortions than the 5K Plus for example.

YES… the Virtuality system was my very first VR experience as well back in 1995! The one I used was the stand up machine and i played virtual boxing against another user and then Zone Hunter and Dactyl nightmare and loved every minute of it! []-)

Thanks for the interesting feedback!
Right, comfort is an important factor. Particularly with games like Alyx that invite for longer-than-1/2h-sessions :wink:
Are you using the MAS or the headstrap with the 8k+?

No, I was talking about distorsions as part of a less clear image.
I hope that the distortions of the Pimax 8KX will end up being the same as in the Artisan (or less).

Sebastian, have you tried sweviver’s suggested distortion fix?

It’s not a typo.
I had my first VR experience in 1993… It was sooooo good!
The road has been long and for many years pretty much closed. Thankfully we’re moving along.

Yes, would be interesting to understand the backgrounds:

  1. Does the Artisan use the same lenses as the other recent Pimax headsets?
  2. Do the displays have the same ppi as the 8k+/8kX?
  3. Are the displays positioned at the same angles?

So in sum - could you completely emulate an Arisan with an 8k-X by cropping?

If yes, then my naive understanding would be that it must be the correction settings in the firmware/PiTool or something?
