Sorry, kuroderuta, apparently some guys are very willng to post a lot but it does not address your question and the topic of the thread at all.
Okay, now this is out of the way: no, that will not work with the 8K. If it did, we would not have the 8K(X). The issue is not only getting the upscaler out of the way, but you need to have a larger bandwith and processing on the headset, which the 8K doesn‘t have. This is also the reason why the 8K(X) needs two DP ports and cables because one single on will not be capable of managing the data throughput. This would in principle not be different with foveated rendering, because I suspect that the data sent to the headset will not be utilizing any compression to take advantage of the less highly rendered peripheral areas.
@mirq: are your posts a sort of an intentional communication breakdown experiment ? It is a bit tiring. I believe everybody get‘s the message, you do not need to repeat it 100 times in each and every thread. Mirq does not like the 8K, and thinks Pimax sucks. Got it.
Why not turn your attention to another subject and come back in March or May ?
