the combination of their 90 hz screens, as well as their software that alternates frames between your eyes , might get pretty close, because the alternate frame rendering is supposed to smooth things out and get a boost in smoothness. we will see. its hard to tell how well it worked on the first one since it was only 60 hz, however the first pimax 4k headset DID get a lot of positive praise. only time will tell.

If the screens are running at 90hz, you can get a 90fps into them. And then if their software alternates frames between eyes, wouldnt that mean it i barely a 45 frame per second headset? That is pretty sucky motion.

You can say you are "boosting smoothness" when cutting the frame rate down to 45 because smoothness can be described as a consistent framerate. And a higher fps might not be consistent and thus, less smooth. However a 90fps consistent frame rate would be better and even more smooth. Just beware of what their marketing department means when they claim smoothness by only displaying frames at half the refresh.

Hmm, what I didn't like about the first Primax was that it was essential a beta product. It ran 1440p up-scaled to 4K, so wasn't really a 4K VR device.

Now that the 8K X will have actual dual 4K displays via DP 1.4, I ordered it. Not shipping until May though. redface.gif So really means late summer. tongue.gif

youre right. I think that alternate frame rendering is just for people with potato rigs to get an acceptable experience, not necessarily to get the BEST experience, also that is optional, theres ways to disable it and all sorts of tweaks in software.

Ya and remember the regular "8K" is only taking in 1/4 the signal as dual 4K displays.

Their FAQ is kinda confusing. It says 4K up-scaled to 8K. But 8K in this sense isn't 7680×4320. It is 7680×2160.

So the actual INPUT of the "regular" 8K would be something like: 3840x1080. That's why they are saying something like a lowly GTX 980 can run it. It is essentially dual 1920x1080 signals up-scaled to dual 4K displays.

The only "real" way you could ever call it 8K is the dual native 4K signal (8K X).

hmm i could have sworn that the 8k and the 8kx both had 2x4k screens, but only the 8kx could actually do native 2x4k due to the double displayport and special chip inside of it. Actually Im pretty sure thats the case.

Only half of 8K.. Real 8K would be four, 4K panels.

They're doing Foveated rendering?! Now that will be interesting, way bigger news than "8K". thumb.gif

That is the case. They both have identical dual 4K displays in them. BUT, the regular 8K is only fed a 3840x1080 signal and then upscaled. The 8K X is fed a 7680x2160 signal native.

Oh and that also makes the interesting fact that the 5K version will run dual 2560x1440 native OLED displays. So that means the 5K will actually take in a higher demand signal than the regular 8K version. And look better doing it!
