After reading this whole thread i also would like to share my 2c
My background: I was following this forum and youtube reviews of the 4k for more than a year, after having bought VRX1 (around the Millennium), io-glasses (VGA, 800x600 in 2004 or so), then playing in 3d-vision with beamers for years, then buying DK1, AntVR, DK2, Vive, CV1, happy about improvements but knowing that that SDE has to go! But reading about the downsides i did decide not to buy a 4k. The (mainly software-) improvements did finally let me buy a used 4k for cheap. Unfortunately i bought a unit with wrong lenses/lensholder combo, but Pimax gave me the right combo free! Even so i bought the 4k used. The SDE was gone, but the dim backlight and the ghosting (not smearing - that was okay) was terrible. Then i removed the shutter-glasses and was much happier having a almost perfect (traded the ghosting for little smearing) picture. Still having strained eyes when using, i did a IPD-mod in moving the lenses about 4-5mm apart (my measured IPD is 69,5). Now i look into the position tracking issue and i will probably order a vive puck for positional tracking.
Pimax is a smal company (comparably very limited resources) which surprised us all (as a chinese company) in delivering constant improvements and not just try to only maximise revenue to a point where their next product really looks good! Like all what we wanted from the big two players in VR, CV2, Vive2 already right in our hands. And they did not want to give us that for whatever commercial (Steam) or legal (oculus-zenimax) reason.
So, yes, again no native 4k, but by looking at the 4k HMD it should be clear that 2x 4k native makes no sense at all right now. Almost no better picture than 1440p upscaled (i trust Pimax on that one) with about half the requirement of gfx-power. And i use a beefy system with 1080ti and i beg for even more fps and cry for every setting i have to reduce for reaching my >45fps goal.
And this brings me to the foveated rendering.
Yes, foveated rendering is not ready right now to be 100% accurate, but i highly doubt that it has to be. Our visual system accepts almost 50% „fake“ frames with ASW and nobody sees it. Also in playing with z-buffer3d only few people see the distortion around close objects moving, and if you watch a normal DVD and look just around a foreground object like a person moving, you suddenly see a halo of distortion around that object.
FOVE would not have produced (and sold) a HMD if the hardware wouln‘t have been good enough. The software base was not ready to adopt, so the time was not ready because of the only little performance improvement because of the narrow FOV and the not so perfect tracking.
BUT i definately think that NOW is the right time and Pimax has the power to change that. Because with a 200FOV you suddenly do not have a 75%-100% performance gain (100FOV), but THREE to SIX times as much (my personal estimate looking at the additional screen percentage). And this makes a BIG difference! Because finally it is worth (or you even need) to use the software tools already here for the needed improved performace.
So, looking in the witch-glass-orb in front of me, the other companies will have to match the 200FOV and this will bring developers in the boat to use Nvidia VRWorks and LiquidVR tricks to finally make foveated rendering an obligation for fluid VR. This is why we need VorpX to jump in, because hardware without a software base means nothing. And the more people see how amazing even 2D games could look, the more people will consider to buy. Yes, all VR is still a niche, but if u can play all the old games you have in VorpX-3d-VR, more people will buy and enjoy that. Maybe even replay old titles like i do.
It is time for a big change and Pimax is right now a big mover. In forcing software to adopt to hardware. So please bring that module to us when it is ready. Every sold pimax with this module will change VR for the better.
For me wireless is a far bigger leap and will not happen before eyetracking with foveated rendering is used within high end hmds, trickling down to mainstream headsets. I think that the second is a requirement for the first and will make it happen that with the bandwith of a tp-cast we can enjoy our 8k wirelessly.
I backed the 8kx and a 8k only to show my support to pimax and honoring their passion for development. I think that if foveated rendering is pushed, every future high resolution headset is earlier in our hands!
Thank you for reading!
