The Crystal Light brings the core experience of the Crystal at a much more affordable price, as well as a lighter package. The Crystal Light needs no battery, as the power supply is directly brought through the DisplayPort cable. The headset and controllers are tracked with built-in 6DOF inside-out tracking, so you don't need to buy any base stations. It's a pure PCVR headset, and a simplified user experience.

There is no additional info behind the link. And this video does not explain anything about compression. Standards for different Hz, samples like BigscreenVR give, reason DP2.0 or double DP cable is not used. 😏
DisplayPort is one of the main reasons I’m switching!
i switch from the HP Reveb G2 to Pimax Cristal Light. I never had problem with the DisplayPort !
Not mentioned in this video is the substantial difference in latency between a direct DisplayPort connection and the remote streaming method used by Quest headsets. Streaming PCVR to Quest produces 50-70ms of latency which mostly comes from the complex lossy codecs that are being used like h.265.
In a flight simulator, this is generally not going to matter. But in a racing simulation it does. Effectively the car is reacting 50-70ms slower just because of the VR hardware in use. The driver will naturally interpret this as the suspension just reacting a little slower and adapt and not feel like anything is wrong. But this does affect your competitive edge to some degree. Your car is responding a little bit slower than it could, and its because of your VR hardware, not the simulation.
If you play action games like FPS, that latency really matters. Fire fights are often decided by who gets in the first shot, and having 50-70ms added to your reaction time is significant. Quest 3 is a lighter headset and that has benefits for comfort. And wireless is nice. But if you want to win, a PCVR headset using DisplayPort gives you a meaningful edge over opponents streaming PCVR to Quest.
Guess what? It doesnt matter. YOUR reaction time is WAY slower that 50ms. Ever maxx V's is. IT DOESNT MATTER
@@silverfoxvr8541 That's not how it works. That 50ms is added on top of whatever your reaction time is. If you react in 250ms, then total reaction time will become 300ms.
If you're firing at an opponent who reacted in 270ms (slower than you), but he's using a VR headset with DisplayPort, he will still get in the first shot anyway.
It won't always make the difference between winning and losing, but it's a meaningful edge. I've lost races in RL by as little as 8ms.
My headset gets roughly 18-20 Ms latency wirelessly
Another benefit no one talks about is due to the display port direct connection, you can take advantage of Nvidia Reflex (granted you have an Nvidia GPU) which reduces latency even more, which I noticed benefitted my experience tremendously in iRacing. I compared results with a few others with a Quest 3 and Pico VR and they did not great results from it (likely due to their compressed output) while my Reverb G2 benefitted tremendously. It was a noticeable difference even prior to looking at fps/frametimes/response times.
The Pimax Crystal is the most beautiful image I have ever seen in VR. The sound is the highest quality & Lenses also, thank you for these videos, as not everyone knows yet, but the new range of Crystals will hit a wider audience ❤
I like how all people on Pimax sound very honest
🤣
Just like they told the truth about 8k resolution or the fov on the crystal
@@yeenybean2881 On the planet? You mean like on their website: "The Highest Clarity VR Headset in the World"
All awesome except 2 things:
1. FOV is not real, is a bit smaller.
2. The size. Even reduction of weight, the headset is very big
fov varies for everybody, the distance between your eye to the lens played a big role, you can try a thin padding to get your eye closer to the lens
I really like this video series. Would love to see what work is being done to improve Pimax software reliability and controller tracking.
I knew that the bandwidth of a USB cable was lower than that of a DisplayPort, but now I understand with the numbers what that means.
An HDMI (DisplayPort) cable is designed to carry a 4K picture, it's that simple.
These little videos are nice and to the point. As wireless is becoming increasingly "mainstream" and often uses much more bandwidth limited methods than a cable is, I think the discussion about compression and latency needs to be had more. Because it doesn't take long to figure out the basics, but it's definitely not readily obvious without at least a little research so it's easy for the average consumer to overlook. Some people don't notice it as much, but it IS still something worth talking about as plenty do.
We may (eventually) hit a point of diminishing returns or advancement in techniques that it'll be hard to tell the difference even for eagle eyed people actively looking for artifacts and sensitive to it and have low latency, but we're still not there yet and especially not on such high resolution HMDs like this. The cable still has a place.
Or maybe we'll finally get Wigig 2 on a commercial product at some point lol.
Not only that, but the latency on display port vs the wireless setup on Quest 3 is a notable difference as well. Wifi 6e still can't beat the low latency values you will get on a hard wired DP setup.
DisplayPort is the reason I am going to buy Crystal Light... And I don't play sims...
When Crystal Light gonna be available on Amazon?
Is the Crystal Light be my next VR headset??? Maybe sometime in the future, but right now I am enjoying my Quest 3 for what it provides me. High Resolution adequate, clarity is very good, the sweet spot is large enough for me. The headset is much lighter and smaller in size than a PIMAX headsets. Plus this is my first wireless VR headset.
Right now I connect my Quest 3 via a USB link cable and works well with my SIM racing games i do.
I am not a META fanboy, I try to find a headset that works for me, and so far the Quest 3 replaced my Rift S for better quality. I have gone through other VR headsets with disappointments with them. And the price was good enough on my pocket book and budget spending.
I will say that the PIMAX Crystal Light VR headsets are on my watch videos list and they do look good for my SIM Racing. i like how they connect via a Display Port to the GFX card. I will wait till they hit the market and watch video reviews on them. Till then, I am back to doing SIM racing with my Quest 3.
Take care.
Can you possible make a video on colour brightness in nits compared to competing headsets somnium vr1
Great overview video guys 👍
Says the most biased vr guy of the community.. 😆
Dude wants to keep getting his free headsets
Thank you! Praise from a top content creator!
Love your videos
@@Godfather1010 Thankyou so much!
Going for the pimax super. I want the auto IPD, dynamic FR, and the ability to change the display from QLED to OLED
Ironic that it only comes with DisplayPort 1.4 so compression will be needed. If it had DP 2.1 it wouldn't need compression and the albeit small amount of latency involved.
@@vrsimracer DSC compression is visually lossless and the latency involved is extremely marginal to the point no human could tell the difference. 0 to 5 micro seconds of difference
@@chadef555 As far as I can see DP1.4a and DSC cannot handle the bandwidth of 8K at 120Hz anyway, I can only find it handling up to 60Hz and that DP2.1 is required for 8K 120Hz. Will be very happy to be shown wrong though.
I'm trying to decide between Pimax Crystal with Wireless module and Crystal Super wired, but it's so hard to choose when I've already got the 8KX!
I definitely want the 12K when that comes, but that's why it's hard to decide whether to get wireless smaller FoV, or wired larger FoV which is still less than the 8KX FoV. I think I can only decide after seeing the final performance and specs of the Wireless module on Crystal, compared to the final performance and specs of the Crystal Super.
The Crystal Light I can rule out for myself, though.
i already made a preorder due to the fact that Pimax offers the best Resolution. i tried the quest 2 and valve index and its shocking how bad the screendoor effect and resolution is on both of them. Also the light doesnt have these weird stations so thats a win too.
wait for Somnium vr1 , it will be much better but more expensive
@@x32i77 no thanks that startup is hella scatchy
You should try quest 3 with virtual desktop first.
@@katzentypha8139why buy from pimax if want to avoid sketchy companies 😂
@@theegodelpozo compression and latency is a problem on Quest 3 as well. It's no different than Quest pro or 2. It's a bit better latency wise but still not on par with PCVR headsets
"Glasses are much better "
Meh if there is one downside to crystal image vs quest 3 its the lenses their distorsion and their sweetspot
Mura on q3 is unbearable
I did not preorder the Crystal Light the first day it was announced. I slept on it and then preordered on day two. And sold my HP Reverb G2 on eBay a few days later.
Hola, se puede comprar lentes 42 para cambiarlas en pimax crystal? Donde? Porque no veo esa opción en la tienda de pimax.
The Crystal Light will be bulky but supposedly lighter that a Quest 2 or 3 with battery straps... will it be suitable for room scale vr? comfortable enough? what do you think guys?
I think it wil be comfortable enough
When wil you start shiping the ones without local diming?😊
we need 4k per eye and 150 FOV for a cheap price. like Pimax Crystal Super Light.! in future.
will the optical DP-wire from the pimax crystal compatible to the pimax crystal light?
Store listing says no. Which is a shame as the included 4.5m is a little short.
What about compared to Apple vison Pro for Resolution to resolution
17M vs 23M pixels, 699 USD vs 3500 USD.
Actually aiming for the Super.
i bought my standart crystal about a month ago its an amazing upgrade from my first headset a Pimax 5k super how ever as good as the HMD is step up your controller game the stand alone controllers feel cheeper then a third party 20$ xbox controller and the tracking is so awful i would rather use the eye tracking sensor that came with my 5k super i case its the inside out trackings fault i would wonder why anyone would even bother with quest or any other headset that uses inside out best thing you can do is get 2 lighhouse 2.0 and a pair of index knuckle controllers paired with a crystal and you get the best pc vr expirence you pc can handle
latency?
ok so how are you guys going to handle the 4k panel oled model time to switch to displayport 2.1?
👍
Still excited for the 12k release in Q4 2022 😂😂😂 How did you guys ever think that was going to happen?
Lenses are better than the Quest 3? Excuse me but the Crystal suffers of chromatic aberration and distortions while the Q3 must be one of the best I've ever seen with a huge sweet spot. And the compression problems are gone with virtual desktop.
While you may be right about the Quest 3 lenses being better overall than the Crystal lenses, native display port connection is allways going to be superior to any wifi network connection. Virtual desktop is an amazing tool, and with a powerful VGA and network setup, it can produce a pretty amazing picture quality, but the compression artifacts are still there even with HEVC 10 bit and AV1 encoding.
@@KRoy1990of course but that sky shown in the video is a lie.
No perfect hmd.. Mura is bad on the q3.. and latency is also an issue especially with VD.
@@theegodelpozo It is not a lie. Added colorbanding can be a thing with lower quality streaming.
GUYS WE WANT EYE TRACKING BACK !!
You already have these options! Buy the standard Crystal or the Crystal Super if you want eye tracking. Crystal Light is a simplified model where you obviously will not get eye tracking for $699.
@@Szabby999 the fuuuckinggg crystal has a fucking heavy battery and a fucking xr chip ipd motors that add weight and a 400 buck to the price wich part of that cant you fucking understand , now you got the light go get it and leave us the fuck alone
USB-C/3.1, 3.2 and 4.0 are not as bad as you claim...Although quite rightly...you are talking about USB + decoder for the Quest3...Without dwelling on that...
it would have been fairer to do so...
However, the Quest3/Pico 4 are autonomous devices with a small battery which rely on a fairly weak decompression chip.
It is this which limits the quality and blocks the bandwidth of USB by using a compression ratio higher than the 3:1 of DP.1.4
Besides, the bandwidth you quote for this one is 32.4 Gbit/s and not 80Gbit/s like that of DP2.0/USB 4....
Why not use DP2.0?
So do the 2x8,5Mp really support a frequency of 90hz in DP1.4? And how?
This is good question how DP 1,4 can support so high resolution on 90/120hz 🤔
That's the question - video about compression, they did not talk about. BigscreenVR with 2.5m screen has to use 75hz uncompressed and 90hz with compression (reported visible on gauges and contacts on clear sky)
@@icekuba Thank nVidia for using 1.4 on their 40 series GPUs
@@icekuba The same way 1.4 supports 4k 240hz monitors - using display stream compression (DSC).
@@unotoli bigscreen beyond is a special case. 75Hz is compressed with DSC just like any high resolution and/or high refresh rate monitors that exceed bandwidth of DP1.4. 90Hz is upscaled on the headset side by internal upscaler since panels controller cannot handle full resolution. However with additional supersampling the differences in sharpness are neglible most of the time.
A decent PCVR only works with a DP cable anyway. Everything else is not PCVR for me 👍👍👍
I'm looking forward to my Pimax Crystal Light👏👍👍
Why are people complaining?
I would buy a pimax if it wasnt so heavy,
Lower the weight of that brick.
Rather buy a BigScreen which is ~500 grams lighter than your headset.
Okay. Enjoy your 72hz lol.
If only it had eye tracking
You already have these options! Buy the standard Crystal or the Crystal Super if you want eye tracking. Crystal Light is a simplified model where you obviously will not get eye tracking for $699.
I still get eye strain in the crystal… none in the quest 3
You better pray to Gabe that Valve doesn't announce Deckard before your release.
Deckard won't happen.
was this video filmed using the pimax microphone?.... jesus you guys are bad.
Will the DisplayPort Cable with the Power Adapter work on the Original Crystal Headset...? It would be awesome to hear it does for the original crystal owners this way they don't have to worry about charging batteries. 🪫😉👌
Make a $500 headsety I can buy used for $300 that has pan cake lenses and You beloved DP cable and Im in.
You can keep your $2000 headsets.-
Your headset is TOO BIG AND TOO HEAVY for long sim races. PERIOD, DP or not.
Crystal Light is a lot lighter
Yeah its around quest 3 wheight
