Q: How exactly do you intend to make sure all steam vr games are playable on the new 5k and 8k headsets without stretching? I have talked to several people whom are worried about proper support. IF this can be cleared up in an official response i can forward the answer. thanks.
A: Maybe there's the answer you want

Pimax 5k: input: 2screen*2560*1440 native output: 2 screen*2560*1440; and both HZ rate 90hz


so now im leaning towards the 5k version.

Am I missing something? How does a regular render go beyond 180deg of FoV? Are they using multiple view ports and combining them?

Optics is getting complicated with flat screens already. If you're aware of any design that can properly collimate a significantly curved close-up HMD screen, please let me know. Otherwise I'd say there's no existing solution.

one view port per eye i think, with overlapping center.

this example is not from pimax.

WHY!?

We can't even handle 4k in the mainstream yet... we can't even handle VR for mainstream yet either... and much less handle 4K-resolution VR...

So why make an 8K VR headset? The hardware required to run 8K simply does not exist in any reliable manner. You'd have to run those insane Quadro P6000s just to have the memory and firepower to handle such a task at this point. redface.gif

its pretty obvious when people dont read the details.

Q: In the FAQ you quote the input resolution to be "4k upscaled to 8k", Ignoring the fact that you're ignoring vertical resolution with 8k... 4k is 3840 × 2160, so per eye that would suggest 1920x2160 or if halved 1920x1080 (1080p). Yet the 5k is suggested to have a resolution of 2650x1440, which is the resolution mentioned in the forum faq and since replaced by stating "4k" which would make the horizontal resolution not that good..(below vive/rift/ms.mr HMD's)
So what is it? Please, can you state clearly what the maximum input resolutions and Hz rate are for both the 8k and 5k hmd's?
A: Pimax 8k input: 2screen*1920*1080 or 2 screen *2560*1440 upscale output: 2 screen* 3840*1440;
Pimax 5k: input: 2screen*2560*1440 native output: 2 screen*2560*1440; and both HZ rate 90hz


so let me break that down for you:

your gpu will be either rendering 2x1080p images, or 2x 1440p images, then upscaling it to 2x4k through the hardware in the headset. Thats for the basic 8k headset.

The 8kx headset will be able to do native 2x4k.

And the 5k headset will do only native 2x1440p.
