@SpecsReader Have you ever read anything else than marketing info about Pimax 4K? I do not have the headset, but even I was able to figure out that Pimax 4K runs at 60Hz as reported by all the user comments and reviews available on the internet.
There is no ambiguity except unless you really want to stick to one line in commercial info and ignore all the other experience.
If you want to do that, please have your quarrel with Pimax directly and do not spam the forums, you already made the same point several times over several threads.
No similarity between Pimax 4K and 8K has been announced by Pimax nor confirmed by numerous reviewers, so your attempt to postulate your speculations about how 8K is the same as 4K are just that, your personal speculation. There is no other indication or support to it.
If you do not understand how brain-warp works (or is supposed to work), it is understandable as not much has been disclosed so far except the info graphics in the KS campaign. Even from that one can draw some assumptions which however will only be confirmed once Pimax actually shows it (or explains it more).
If it bothers you that much, please address your concern to Pimax too and do not come (again) to every thread by saying "it is terrible, I do not know how brain warp works".
There might be some benefits to brain warp (to be seen) but there are also some drawbacks (which were already discussed here in the forum), so the overall is the mixed bag and that is the reason why I am really not bothered much (and I assume others as well) by the brain warp.
