Ah but if you beleive Starbreeze their StarVR at 2x 2.5k (qhd) is not able to be driven by consumer PCs. Of which we know is false to a point.
The 8k model is in truth not 8k resolution. It is 4k/eye. Now if the PiMax team supports "4k" like they do now in the 4k model (FHD & QHD interpolated to 4k) will allow gpus to run the 8k model. & native support for those who can push 4k/eye.
The 8k model with using 2 panels (may need to keep dual Inputs for display) allows them as they 1st presented the idea of the 8k concept to reduce required gpu power by alternate eye rendering. This way the GPU only has to render 1 display panel at a time.
The 8k model will need to be able I surmise from reading up on StarVR will need to upconvert FOV for games that don't support that high of FOV. This is also why its important to get Dev kits out to game makers like DCS, Warthunder, Prepared3d etc.
With no other hmd maker making a consumer available hmd (StarVR is not available at the consumer level) will help cement PiMax in the VR market.
Now the real question can i trade the positional tracking for the robotic sim? Lol
Now for sure they need to continue to improve the 4k model & eventually release a Version 2 with all they have learned (hard & soft ipd adjustment, manual focus etc..)
Now I am certain @Enopho with his crazy VR Ready GPU would have certainly very little trouble running the 8k model lol.
The 8k model will certainly be a favorite for business wanting to create rides & experiences.
