Dear Reader.
I ordered the Pimax 8kx in end of October 2019, and today 10 september 2020 it arrived to my big surprise since I never recieved any track and trace information but only some letters about they where getting ready to ship my 8kx vr headset… It was actual a nice surprise to wake up and see there was package and it said pimax on the side 
The packing of the product was good and it have nice black protective foam in the box that kept the vr headset in place and the cables where rolled arround a circular device.
There was plastic arround the box so water/rain could not damage the product during transport.
I instant notised that compared to pimax 5k+ i no longer needed a power adapter and only had to pluging the Hdmi, usb 3.0 ( blue usb connector ) and usb 2.0 cable. ( black )
Actual pimax vr headsets are not new to me, i had pimax 4k and pimax 5k+ and now pimax 8kx and to let you know the pimax 8kx is really the best in the series since it feel better, the tracking is a bit better and ofcourse it have a much better picture, and its actual like looking at a monitor but in VR. I have personaly had vr equipment for many years and im so happy that FINALY the image is like looking on a monitor with no pixels visible and that i now ingame actual can read even the smallest text.
Dont get me wrong the pimax 5k+ i thought was really great, but i could not in dcs world read the small white text in the main menu about dislaimers… But the when i tried the 8kx i could read it clearly.
My render quality is set to 1,5 and i used normal field of view and dident turn on forward rendering or smart smoothing, like i sait i just got the headset today and dident tweak it yet ).
In the cockpit of the F16 ( that is a bit small cockpit compared to other planes/heli ) then i could read 99% of all the text without leaning forward or anything… The only text i find difficult to read are on the navigation screen inbetween my legs where you tune heading and can read distance… these tiny numbers i have to lean forward 20cm to read the text, but that is no big deal at all. Els all labels in the cockpit is readable and ofcourse looking out the cockpit window is like looking like if you played on a monitor. Well im so happy about the quality FINALY a vr headset that have “monitor quality in a vr game”.
The performance…
My computer ryzen 9 3900x ( 12 cores/24 threads ) 3800mhz boost up to 4700
Nvidia 2080rtx oc from gainward
32gb ddr 4 ram 3200mhz
m.2 and ssd harddisk.
windows 10 pro, 64 bit.
Steam VR Beta.
Regarding performance i configured pimax 8kx to run in Normal view mode and i was able to run dcs world at 72hz, ( the build in fps counter say 32-36fps and i imagine its pr eye. )
In case you wonder pimax is working on 90hz and 120hz for pimax 8kx but its not quite ready yet.
To me it felt fluent especially flying, while parked on the ramp in airport it felt a little slower. I like to say I did not fly a real mission yet with many enemys or in multiplayer, but i imagine that fps will drop especially in multiplayer.
My recommendation…: The 2080rtx is a great card that can run almost all games on ultra, however for the 8kx i like to recommend to invest in a nvidia 3070rtx or higher for the very best experience. By the way nvidia 3070rtx is like double the speed of a 2080rtx by the way and will be out in about 10 days from now.
The negative…:
1). i think the IDP ( distance inbetween eyes ) is wrong and it only goes to 70mm.
I have a big head and i am lucky i did not have to go any higher… I think my IPD for pimax 5k+ was like 63-65mm so there is some difference. I dont know if its a software problem or if its a hardware design problem.
2). The new comfort head strap on is really great and it fell good to wear it and it dosent feel cheap as the rubber band straps on pimax 5k+ that actual is pretty decent by the way.
However the foam/strap that where you tighten to the back of your head feel like its sitting up way to high, but i know pimax in another forum topic is offering a free metal/plastic thing that changes the angle of headset and you can get this for free if you write in the forum and tell them your order number. 
I dont know if i need this but i have ordered one.
3). The vr headset and cable feel more heavy than the pimax 5k+ and maybe i will add some weight to the rear of the headset for a better balance.
4). regarding the purchase process and waiting time… sorry to say i think it was a mess. I have been a client for years and i have two different login pages where i can see my orders one on pimax.com and on pimaxvr.com and its not the same “thing”. I did along the way refund my base station and controllers and bought the valve index once instead, reason i could get them here and now, while i belive pimax still havent send out theirs just saying im glad i dident wait for them.
5). To get the best picture its very important to find the sweet spot of IPD and to possition the vr headset correctly on your face… It have quite a low tollerance… And just like with 5k+ and now 8kx i advice people to push your vr headset a bit up/down/left/right and also tilt it forward until you find the best setting for you.
So it do take a little setup time for best experience.
All in all pimax have become better since it was really a mess, and backers have really kept up with allot of stuff. ( ps… i dont understand why i cannot login while im connected to a vpn on one site, but not on the other…)
What i like most about pimax is the wide screen, but also that no pimax headset have EVER made me VR sick from using it… I had allot of problems with this in Ocolus rift wich was my first vr headset.
Anyway long story short im happy about the 8kx this is how VR should have been from the start 8-10 years ago
its really a game changer BUT VERY EXPENSIVE… anyway the future for Vr look very good now and if the 8kx will be the new standard in the future for vr then we are all in for a very good future. 
PS… now i look forward to the eye tracking module getting shipped, and that i can buy hand tracking and especially that the hand tracking can be used in flight simulators.
PPS… I doubt that reverb 2 will be better than pimax 8kx the image and widescreen is fantastic and i can read all instruments clearly in cockpit of dcs world.
