From the way the Kickstarter described it, it sounds like this is the case. Anyone know? If it is, I don’t see why they couldn’t run native 4k at 90hz. After all, it seems like the issue with the controller was that it couldn’t handle two 4k screens at 90hz. Now if only one screen is on, and it’s just flickering between them, shouldn’t native 4k be doable? Even if it’s only at 60hz, the whole point of brainwarp is to increase perceived refresh rate.

i guess your question is : does 120hz brainwrap feel as good as a traditional 90hz timewrap? I’m afraid we don’t know yet, but if it does then sure we can gain some fps in some scenarios and do 4K.
I was wondering about this myself recently, my thought was what if one panel actually just showed the same frame twice instead of nothing (nothing as in like active 3D shutter glasses where one eye is turned off), would that be even better?
I can’t wait to learn more.
Probably not a great experience. I think the idea is that only one panel is displayed at a time. If you display the same frame, say on the left panel, then the left panel will be displaying old data while the right panel will be displaying new data. I’d guess this would be terrible (maybe make you sick, get headaches, or just be very disorienting because it’ll mess with your depth perfection (because objects in the scene will appear to have moved differently than they did).
Edit: responding to @Wiinii, not OP
The original description of brainwarp discussed introducing an alternating black image. Since then, there have been some rumors that one eye will see a reprojection, instead of black. Of course, it would still draw one fresh frame for each eye, every other frame (like before).

if you still need to push two 4K image at a time you will still be limited by the bandwidth lag. Which mean by the time the second screen is shown : its positional value would be wrong. That would make some people sick.
the main goal of brainwrap is to push only one 4k image first so that we can apply brainwrap later again for the second eye. This minimize time to photon. in simple world brainwrap only delay the timewrap for the second eyes so that we don’t positionally suffer from the transfer lag.
Brainwarp is in “let me ask our developers” mode. Pimax is avoiding any sort of discussion about brainwarp. Testers have no mentioned it.
I would not expect anything from brainwarp right now. It might come and be great but you’d be wise to prepare your PC to cope with the headset without it. Considering the new minimum specs I don’t see pimax being very optimistic anymore.

It should be no more disorienting than a blank screen would be, you wouldn’t really even see it at that speed.
That’s kind of what I had in mind, makes more sense than a blank screen.
I’m all for trying it, but I know your brain handles “no data” very differently than “bad/incorrect data.” Like the difference between walking blackout drunk and walking in the dark sober.
Brainwarp doesn’t make it at all.
