CV1 upgrade to 4K [ PIMAX 4K ] + positional tracking PS Move

looks NICE, compared its display:
BE: 2560X1440 OLED with 85Hz [ up to 150Hz ] * 3.7MP / ?
4K: 3840x2160 LED with 60Hz [ up to 120Hz ] * 8.3MP / 806 PPI
looks like a trade: LessGhosting vs BiggerSDE
[ both still lack of PT... and seems that available for Chinese Business only ? ]
+ BE is much lighter: 360g !
I will hold my 4K, since it is a 4K till a CV2 arrives don`t you think that PIMAX 8K would be an overkill ? [ actually twice a 4K display ! wonder if 2 x SLI 1080TI GTX - will hold a 15FPS with LOW settings untill will be melted beautifull dream of native 8K - but needs *next gen. of GPU of 2020+ or to use it with 2,5K / 4K GPU res. with upscaling, since no SDE, but then what`s the difference 4K which SDE is already unnoticable... ]

Check that in some part of the page says that it was "Chinese business only" until now, that is available worldwide from them
To be honest, I only keep my cv1+touchs because I want to use them with my wip simulator, meanwhile they are collecting dust, even my daughters almost doesn't use them, the lack of software is killer.

for me the opposite 4K stays, and CV1 leaves [ since I can`t get used to SDE again as I`ve seen a 4K - maybe better was not touch a P4K from the beginning / similar situation had after my first VR experience, when later cannot simply force myself to watch/use a flat screen anymore ]

Agreed, I think I would use the pimax4k more than the cv1, impossibly to think about my sim without VR.

From my order tracking, I should have mine in 7 to 10 days .

FAST ! I was never strong in case of waiting for packages like this [ especially a new VR HMD, I remember the DK2 preorder: 2 months untill my turn in production comes + 2 weeks for delivery = it was really difficult time for my patience ]

PT + DCS + P4K [ some kind of selfie movie ]:

does it eat gpu power tho to run 4k ?

Unfortunetely yes, if native 4K then my 1080GTX would be melted with 25FPS [ with OC ], but PIMAX 4K uses 2.5K resolution and HW upscale to 4K, so it is 4K VR for current GPU !
[ for example using SuperSampling as I did for CV1, to 2-2.5K = same requirements / DCS on Ultra constant 60 FPS - GTX@1080 ]

PT looks good . Order Tracking tells me that my PIMAX 4K arrived in Sydney yesterday - should be delivered tomorrow . I'm really interested in how this will look in real life - unfortunately videos don't do anything for previewing a VR system.

Great !
You need to ensure you have a solid 60FPS, I reinstalled drivers and make tweaks, tip: SuperSampling is on PiPlay and Steam - check that you don`t have 1.5 * 1.5 [ or if needed need to lower game settings ].
and set up the IPD [ PiPlay -> settings -> device . I seen it kind of blurry, untill set up properly my eyes ]
At first you should notice the ghosting [especially on SteamVR ], but later you won`t notice it, especially during playing games like PCARS - what you will notice is a crystal clear dashboard details !
+ later make a simple PSMove PositionalTracking like I did to improve the immersion.
Look forward to your experience with first 4K available I think you won`t be dissappointed !
PS: also please check on serial of your Pimax, since 100 is a 4K led, and 102 is BE with 2.5OLED [ I heard they`ve messed up many shipments ]

Ok, thanks for the heads up ..

I think 1.8 ppd is the limit ai t it and your just killing gpu power off to which you can then use the game and get more from it than going over the ppd of 1.8.
Think hhe screen top out at that. So it game settings or nvidia dsr 4x
Think i just run dsr 4x time now n crank up the games but been going thru so mamy changes on my pc its nig funny now.
Lol
Gtx 1080ti rog posiedon now, but delivery tomoz for a new build to do so upping every thi g abit more.
I. Intrested now as was going to buy another cv1 for the garden so i got space ! Lol
This would work in my favour if its good.

Yes, still for a native 4K/8K in VR even the most powerfull GPU`s has their limits and nothing helps untill a next. gen. GPU will be produced [ I can understand this ],
but Pimax resolved this issue as a 2.5K GPU rendering, and HW upscaling to 4K = this is what the @Oculus/@HTC should have thought about a months ago [ or even years ] !!!!
Really cannot understand why they are staying with a such SDE [ from 2 years ] waiting for a progress in CPU/GPU probably... Pimax on the other hand is now developing 8K [ so not answering on technical forums about any fix request for earlier 4K - like they are 95% focuses on 8K ] - which will be an overkill [ even with rendering first for left 4K, then for right 4K = yea, some optimalisation for 2 displays ] but PPI is still too big to be handled ! but they don`t want to listen / have seen many posts of angry people about 8K priorities in DEV [ including me ].
I`ve also read lately that on earlier versions of PiPlay [ like 1.1.92 ] ghosting effect and drifting was less noticable, like it is additional SW issue [ HW mostly offcourse ], so tried to check and made a downgrade [ at this weekend ] but without success unfortunatelly [ SW was not founding my HMD all the time - uninstalling Oculus/PiPlay/Drivers reinstalling in many configurations, unpluging/pluging => still don`t know why, but hadn`t got enought time, and installed again the newest 1.2.75 - works OK ]

Af the end of the day the tech is always moving forward but the only thing that will solve vr issues is 2 gpu support in the games.
They need to get that working so it will work with 2x gpu one for each eye not in sli tho just seperate gpu for each so you have full power to play with.
Once thats done it will solve so much on the power side to run vr at an amazing rate.
Fps noprobs graphic ultra ect...
It may only need the pimax res then anyway.
Its about time dedicated real games are just vr to move the tech forward and stop thinking about the bloidy money.
They will make it if its amazing n i don't mind a £100 game if its done right.

Yes, but still VR is the most expensive as for its hardware requirements [ if a new 1080GTX costs price level 800$ and you will need *2 of highest level card + HMD, like CV1 - another 800$ + CPU with MB for 600$ + some peripherals like wheel, etc = it is only beginning of the whole investment... ],
when trying to competitive and bring to mass end-user [ to make it more popular / create huge market ] for everyone, as Sony tried with addon of VR HDM to PS4 [ 500$ total for a console + 400$ VR ] it simply cannot have enough power to handle [ even with low level programming optimalisations ].
Still without further HW + SW changes in GPU architecture [ like nVidia did with ASW, ATW ] it will remain as unfordable [ on entry price level ] for most of the people - especially comparing to what can really offer as barely 2K and SDE, but... it is a price of evolution I suppose, to be a part of it
also as you said Pimax resolution is what it really needs to fit VR expectations.

@SeatTime - and how is the status [ have you already received ] - first impressions ?

Well my Pimax '4K' turned up, but unfortunately it has a BE panel fitted - serial number begins with '102'and I can see a SDE in the panel. Email to Pimax support sent .....

I heard that they are messing up with many shipments... but should exchange without a problem [ so if you already have it - untill any further move - it is a good opportunity to test the BE version
2.5K is still higher then Oculus/HTC so SDE should be much improved - I suppose and should have less ghosting as higher HZ - then my 4K - so how`s first general impressions on the Pimax BE, or it is still too early and you need to test it better on games like PCars ?

Just got home from visiting friends up north, have only looked through the lens with the setup, although with just that it seems very clear - no god rays like with my Oculus. I will see if I can get something else running.
