I still have faith in the Pimax team. I've switched over to a Samsung Odyssey because i broke my PImax BE. While the Odyssey is an excellent product I can recommend, especially because tracking is built in, I still kinda miss my BE model for two reasons.
I had an older PC up until about 2 weeks ago. And I was having a Better experience with the BE than I did with the Samsung in my favorite VR program, Lockheed Martin's Prepar3d 4.2.
First, I Did Not Get Dizzy in the Pimax. I think this is specifically because of the framerate doubling method they are using in their headset. The software I used as a VR overlay for Prepar3d, FlyInside would say I had a certain framerate, even down to 20fps, but the experience in the headset was smoother. I did not get VR sickness in the Pimax BE. I think specifically because of their Brainwarp technology. Now I have newer PC and I have not been able to try the broken Pimax BE, but even with double the framerates sent to the Samsung Odyssey, I get VR sickness! This will probably be solved when I rip one of those 1080 ti from a miner, but it's a noticeable issue that needs to be resolved that I didn't have with the Pimax BE and Brainwarp Tech.
Second, Pimax BE did not have those GODFORSAKEN GODRAYS!!! OMG I hate seeing them, they make a whole flight GLAREY. Why the Hell are they thinking that these stupid fresnel lenses are the path to go when every Knows eventually to get to the highest quality they will have to go to a regular lens. Seriously bad choice fresnel lenses are.
Actually this kinda brings in a third issue. Even the Samsung Odyssey is still limited by bandwidth issues. The Pimax BE works up to 90hz, but not without an HDMI connection that could run it. I am still on a GTX 780 SLI setup and I'm limited to 60hz on the Odyssey as I was the Pimax BE. Yet I get dizzy on the Odyssey. The Odyssey and BE have the exact same actual resolution.
OK, now a 4th issue. Pimax software actually worked more seemlessly with Vive Steam VR programs and any VR program. The Odyssey requires the overhead of the Windows Mixed Reality program running, and I can tell there is a little bit of performance loss with it. Pimax allowed programs to run a little lower to the drivers and stayed out of the way more.
Those 4 items, along with the build quality of the Pimax BE, are why I believe that Pimax is going to do this right. I don't know where they are on the fresnel lens issue, but I do know for such a small group they are extraordinarily talented and definitely capable of paying attention to detail enough to pull off the Pimax 8k. I think they are our best hope on the wide high res VR experience we're all looking for, and if they need more time I'm almost certain any other group would lag behind even more ... because they are.
