Tech Talk #22 : Pimax Crystal

Angry bird

Is it just me that reads that as Sh1tfall?

me too, but it was an year before…

Or even the year before that one. Although back then I think it was still called Panasonic. But yeah it seems things thing will always be in development.

Nice to see what looks like an actual production unit! No more vision series blue headstrap, and the controllers don’t have the clear ring! This picture is pretty exciting. Can you confirm if this is a finished production unit? Also nice to see the MR faceplate, quite intereted in it also.

This does actually pose quite a threat to the Crystal I would say. Obviously the 12K is totally fine. I do wonder if the meganex will tether to a phone to watch movies and such, that would be a nice addition.

Also, seems like they must have dropped their intentions on adding in their own controllers. Afaik that has been the major delay this whole time, so I guess they just gave up. Especially because it no longer has those drop down parts which I think were originally for controller tracking (I think magnetic like the pico neo 2).

I will say the tracker looks very slapped on and not elegant at all but if it sits on well and doesn’t add much weight then I don’t have any issue with it.

Just wish I hadn’t backed arpara on kickstarter lol.

not sure why there is that kind of hype now, its not new
Jan. 2021

Jan. 2022

(and still no release date, just another prototype - and who does not remember the wide fov prototype from 2017? - anywhere to be seen?)
also when taking Kopin’s reference specs its just 95° FOV - well, who in this forum would want such a small fov when 120° hor. is considered small

and even if they improved it, from the hardware design does not look like it would would be able to come near 120° hor. fov

also when taking needed lighthouse and index controllers into the equation … 900€ + 300€ + 300€ its not impressive at all for just a “gamer” headset, imho meta might have more success with its quest pro as it would at least offer some geeky software for meeting in a business environment
gamer that are new to vr are more likely to end with a pico 4 or a quest 2, way cheaper

i dont think its any harm to the crystal, more geared for business as the quest pro

What would be the best ways to get setup to purchase the Crystal when its’ first release or it just the luck of the draw?

Who gets first dibs, original kickstarters, previous customers, anyone know?

Interestingly, if you move the dots above the Pimax logo it looks like a smile, right?

I think people are excited because of the comfort/form factor, high resolution and PPD, OLED colours and HDR.

Yes, it’s very different from a pimax headset and the FOV sucks but it’s still appealing in its own strengths and the price is much more affordable for many here that are already in the lighthouse ecosystem. Personally I won’t be getting it but I can understand why some would be excited.

I would love to see
DCS World (and more MSFS @SweViver )
as stated before by @lolof. For me to see how the clarity on the gauges and distant objects improved to the 8K X.
Also I would love to see
Alyx
the dark and colors, also maybe again - a shot from the “glove” where you can see the components like back in the days… ( in this thread UnBoxing 8K+ and a mini review )

https://community.openmr.ai/uploads/default/original/3X/d/5/d51f9909974ae6bac3691f2eabc869e6b1c74762.jpeg

And of course, some VR DLSS Games - like Assetto Corsa Competizione, maybe F1 22 (haven’t played that one) and No Mans Sky.
Automobilista 2, Dirt 2 could be interesting, The Walking Dead – Saints and Sinners or After the Fall?
Maybe the not so known Legendary Tales?
Or if possible, @LukeRoss could get some of his mods shown? (Elden Ring, Cyber Punk,… )

I’d like to see a 3rd party reviews please.
Performance numbers on PC games and sims.
Evaluation of the controllers on Steam games.
Pretty much anything one usually knows before being asked for money.

The way Tyriel Wood does through the lens videos is probably the best out there. Note how he shows increasingly zoomed video until you can make out the individual pixels. And then compares them both A-B and side by side in the same frame. Really good for actually seeing the real display quality. Would like to see this kind of comparison between the Crystal, 8KX, Aero, and Index.

Most other through the lens videos I’ve seen are full frame and taken with hand held smartphone cameras. And those really won’t show you anything as far as comparison between two VR headsets. Mostly you’re just seeing the limits of the camera, not the headset.

Not sure if someone posted this before ? Looks like TTL from mobile phone.
We don’t know in game settings but looks nice. The frame rate will raise over time when MS FS goes with more gxf 4xxx series patches

Yikes 50fps on a 2880x2880 headset. God only knows what the 12k will get. 25fps with a 4090? Anyone with a 3080 like me will be down to 12fps. Lol

Any for Pimaxes/Swevivers information that bogus 12k video with outdated specs is still there and needs to be removed.

With MSFS, the graphics card is less of a problem. The system and the CPUs, which are still too weak, slow it down there.

In other applications, the 4090 is nice capable of handling a 12k.
This is e.g. Project Cars 2 in high resolution (with PP) at 90Hz (8kx, Normal FOV)

That maybe so, but Swevivers is using a 5950x processor that goes for ÂŁ530 in the UK.

What happens when you double the res on a 12k and you’ve already got the top cpu? It means your fps is going to halve.

No, the graphics card can hold the frames as it is not full utilized by the CPU.
In addition, just because your HMD can display e.g. 10 million pixels, you are not forced to display them. 5 million still looks better on this than 5 million on a native 5 million HMD due to the pixel density.

I can tell you specifically about mSFs that the switch from the TiRex (3080 equivalent) to the 4090 only gave 5% more FPS. But the image quality has increased by 200%.
This corresponds to what I was hoping for. Only handling and speculating with fictitious numbers is often far from reality - lol

That’s not how graphical scaling works. It’s not a 1:1 loss with the pixels you render. Hell, look at the 4090’s scaling at 1440p and 4k. Per places like Hardware Unboxed and using a 5800x3D, noticeably better than a 5950x for gaming, they went from 215FPS average at 1440p to 145FPS at 4k. they gained about +51% reducing the res from 4k, but the pixel count between 1440p and 4k is a 125% increase, approximately 3.7 mill vs 8.3 mill pixels. Things like being CPU bound can muddle things, but the point it is NOT a linear 1:1 increase. Even in cases where you are very GPU bound, like with Cyberpunk, results were around a 75% FPS increase going from 4k>>>1440p. Which is still a hell of a far cry from the 125% resolution bump.

Hell, even looking at Nvidia’s own slides for MSFS(In flatscreen, granted), MSFS is near completely CPU bound at 4k because with DLSS 3.0 the soon to be rebranded as the 4070, which performed worse than the 3090 TI, was doing almost the same FPS as the 4090, despite the 4090 being crazy more powerful in nigh everything else. But as you go to higher res, you’ll become more GPU bound. To reference HUB again, in a case like this they had instances where the CPU bound 4090 was only around +30%~ the 3090 TI at 1440p, but then the gap grew to > 50% at 4k in the same game. Despite the higher res, the stronger GPU disproportionately benefitted. Depending on if something like MSFS is STILL CPU bound or not at a far higher res than even this, the performance may not be as big a penalty as you’d think if the GPU is getting to shoulder more of the work than being bottlenecked by the CPU. MSFS is easily one of the most CPU intensive games we have out right now, and even GPU intensive. I don’t think anyone honestly expects to run MSFS at native FoV/Res of the 12k, but it’d still look a lot better even reducing the FoV significantly, and resolution by proxy, because of the much higher PPD.

I know you’re quick to doompost about Pimax and there’s plenty they do deserve grief for, but wait to see the performance metrics for a claim like that to better test and analyze. There’s a lot which goes into your overall performance beyond ‘moar pixels’.
