8K 200 degree FOV room scale VR.

Can you point out where you got that info? Is this the 5K PiMax on Kickstarter?
I am trying to decide whether to get the 5K or 8K (I only have a nVidia 1060 GPU)

per the kickstarter the 5k is identical to the 8k with regards to screen type - its just a lower resolution panel

"A lighter option
It's always good to have options, so we are also offering a special 5K edition for Kickstarter. Pimax 5K has all of the same features as Pimax 8K, apart from a difference in resolution and, of course, price. The resolution of 5K (2*2560x1440) is less than 8K (2*3840x2160), but still places it above many of the current headsets on the market. A 5K resolutionis good enough to eliminate screen door, and ideal if you are not as deeply concerned about pixels."

Initially I got the 5K but after seeing confirmation that the SDE of the current 4K model is smaller than the 5K (5K is worse) I made a "financial sacrifice" and went to the 8K model

It was initially from here as this chap tried the 5K OLED and 8K LCD at IFA a few weeks ago: http://forum.pimaxvr.com/t/full-pimax-8k-and-5k-review/2778

However things may have changed, as I know the specs have been somewhat fluid as they work towards the final kickstarter specs and what they can achieve before delivery, so it may be an option only or dropped now. If you can get a direct response on their forums its best to ask there, as their staff are quite responsive.

Just to give you guys some kind of idea, here is a quick picture taken from my iphone through the lens of the Pimax BE unit - the Pimax BE is essentially a 2.5k OLED headset.

Here is another one - The ghosting on the blue text seems to be apparent on the picture, but I really don't see it when playing the game - not sure why that came out like that on the iphone

I'm currently still going with the 5k unit, I am just a little concerned that if I got the 8k one, my GTX 1080 would not be powerful enough to drive it with Elite with all the bells and whistles turned up.
The 2.5k is doing great with everything maxed out on Elite and Steam Super Sampling set to 1.4. I get the occasional Steam not responding, but only when dropping into a system from witch space, never during actual gameplay (combat etc)

Due to bandwidth limitations, the non-X version of the "8k" model will use the exact same 1440p render target as the "5K" one, so GPU load is exactly the same for the two models (...and you could always undersample as well).

...so it becomes a matter of A) whether you want to maintain the level of SDE you have in your current unit, which the "5k" one will not do, given the doubled FOV, and B) Whether you trust the on-HMD video scaler to produce output of acceptable quality.

Of course, the 8K model won't have even less SDE than the 4K. Since the 8K is just two screens @4K each. Due to the larger FOV, it could even be that the SDE ist a little bit worse than than the 4K's one. But I suppose it to be still far far better than any CV1 or Vive SDE, very close to the 4K. The 5K will have two screens @2,5K each which also should be quite a major improvement over CV1/Vive. I once tried a 2K-VR (3glasses S1 blubur), and even this one had noticeable less SDE even though it wasn't at the 4K's level, of course.

Chromatic aberration - more to do with your camera position compared to your actual eye position than anything else.

The 5k is basically a 2k VR screen (1440 vertical), so it will have slightly better SDE then the Vive or OR, but not by much. The 8k is the one to go for. I just don't have the GPU power for it (AMD Fury). But I may go for the 5k version, see what it is like, and if it works well, sell it, sell mr Oclucs Rift, sell my AMD Fury and hope I have enough for a better GPU and the 8k when it comes out. But then I will need to update my CPU, motherboard and ram, as that is way out of date too.

The GPU power required for the 5K or the 8K is the same.
The difference between the 5K and the 8K is the 8K upscales the 1440 image.
The 8K upscaling hardware is in the headset, all processing required for upscaling is done by the headset.

EDIT: For clarity I am referring to the single cable 8K version, the 8K X version that uses 2 x DP has significantly higher requirements.

Yep, this is stuff I know already. But re-looking at the Tech Specs it says minimun of an AMD R9 Nano, as my GPU is better, it should be able to work, I will just have to reduce the settings somewhat.

Decisions to make I think.

Your Fury might be powerful enough: Before owning the ASUS 1080 OC I have since February, I had a Sapphire Fury Tri-X OC @Default manufacturer clock settings, and I played ED @Pimax 4K from January till February with it without any problems. Of course, I wasn't able to raise in-game SS to its actual setting with the 1080 (1.4 instead of 1.8, if I remember correctly; not really sure anymore). I simply went to the 1080 to increase SS a bit more and to have some buffer, and of course, ED and every other VR game runs a bit smoother with it than with the Fury. But even planetary offroad or dogfights in an asteroid field worked very well with the Fury. Only In-Station and planetary stations sometimes were hard to the limit when there was a lot of traffic - but apart from this, everything was fine. Unfortunately, I cannot tell you whether the Fury was sufficient for Project Cars or Euro Truck Simulator 2 since at this time, SS in SteamVR only worked with work-arounds which I never tried. And playing Project Cars or ETS2 with default SS / HMD quality simply was a pain even though the lack of any SDE.

 

[Silversmith]

I'm Confused. Does ED support 8k images natively at source? If not using an 8K display cannot show any enhanced detail, all it can do is upscale the source image from ED. Upscaling cannot add detail, indeed there must be some degree of loss in the upscaling process. So why would one bother ? (apologies if I'm being stupid, not a video expert)

I believe ED can support up to 16K rendering and that would be "proper" 16K i.e. 4 x 8K 16:9 panels worth of resolution. Provided the field of view thing I mentioned in a previous post isn't an issue then we should be good for some time to come.

 

[Kimosabe_X]

Given that you're able to play ED in "4K" resolution (3840x2160px) and there are much more details, so yes there is no upscaled stuff when using this, at least on monitors. And you're able to make high resolution screenshots which have a even bigger resolution than that.

Hmm... I think that's the reason why I don't like my Vive so much, because I'm used to my UHD Monitor and all it's little details and the VR resolution is a severe downstep for me. That + the visible pixels are nearly gamebreaking for me, so VR immersion and experience back and forth, I'm finding myself always returning to 2D in UHD... Sad...

Maybe the Pimax will set that straight and also provides the "optical immersion" for me... Still just worrying a bit about the proper implementation when it hits the shelves...

Exactly my experience and opinion and the reason why I don't like the CV1 at all. Since I first played with the 4K, I know how VR may look like - not as good as UHD, but certainly not worse than FullHD given the fact that you're in VR. In contrast to this, CV1 is like playing ED or Project Cars in 1024x768 on a 28" monitor... (no - I never tried this )

 

[masCh]

Urg, I still can't decide.

From my understanding, the SDE on the 5K would be worse than the 4K.
The 5K has pixels per inches 490 PPI whereas the 4K has 530 PPI.

But SDE isn't really just a function of PPI, it also depends on colour pixel layout.

The Kickstarter discount for the 8K is gone. But the 5K is still around.

So the question now is really whether $150 difference is a good enough "investment" to get an integrated upscaling chip for higher res screens. Thoughts?

Yep, this is the same issue I have too. I think I will likely go for the 5k, and if that is good and works fine with ED, then I can sell it with my Oculus Rift and hopefully have enough for the 8k when it comes out on general release.

I was waiting for the new windows mixed reality headsets to see how they behaved. But by reading the current reviews they have the same issues of SDE as the current Vive / Rift, so that was a disappointment.

I think the 8K model with its upscaled resolution and with no SDE (or very little) is my dream when it comes to VR. That's why the value is already worth it.

Also 200 FOV. I do not see anything on the horizon as a better option to this in the short / medium term.

And I always followed the reviews and forums about the current 4K model and everything I saw was always very good. The company has always tried to improve and evolve the product. Just had not bought it before (4K) because it did not have the controls.

 

[loribee]

Given that I'm trading up from the Pimax BE edition (which is essentially 2.5k) to the 5K, am I going to get a better SDE? - The 5k is effectively double the resolution of what I am using today (and am very happy with to be honest)

I have a lot of respect for the company. They definitely keep improving and re-iterating with their current gen, and also they seem to be all in on partnering with others to expand the ecosystem, instead of trying to do it all themselves and overstretching.

For me it was no positional tracking.
