@xunshu I think this suggestion would be a positive for your approach to business edition hardware, but also for your general consumer HMD.
I know the company does not develop games, but I think it would be a good approach for Pimax as a company to incentivise developers to incorporate explicit multi-GPU support for the software meant to be used on the 8k. NVIDIA has the likes of VRWorks, Pimax should have a means for devs to optimize for unconventional configuations.
With the emphasis on premium clarity and high FOV offered by your HMD, developers need (now more sobthan ever) to have access to all the pixel pushing power they can get, for as little money as possible. Thats especially true for enterprise customers who already have multi gpu rigs.
With memory shortages being what they are, and crypto mining making GPUs more and more expensive, and next gen gpus likely to be offering the usual 20% increase in rendering power, better multi gpu support is going to be an important means of making very high end VR more accesible to more people at lower cost.
As of right now, Nvidia's next gen GPU is propably going to cost $1000, and cards like the 1080 are still $539 .
Multi GPU (properly optimized) can make lower end cards like the rx 580 suitable to deliver about the same performance as a 1070.
It seems to me that VR will face (or is facing) a bottleneck situation. The displays are getting to be higher in pixel count, higher in refresh rate, etc. but computing is having trouble keeping pace.
Even if you implement eye tracking with perfectly implemented foveated rendering, the returns are about 45% improvement in efficiency. This isnt enough though while GPUs are so expensive relative to the modest increases in performance that we see generation to generation.
