My review may be a little late, but since I love the 8K Plus I want to add my impressions
I own the HMD since about a month and bought it to replace the 5K Plus.
And I must say that it was worth it.
A big improvement over the old black case of the 5K Plus. It feels more stable and much more valuable. The case of the 5K Plus with the cracks and co. never really bothered me, but the case of the Vison series is a huge step up.
Also a great new modification that makes the headset much more comfortable. Unfortunately the original face pad is too thick for me.
My eyes were too far away from the lenses, with heavy distortions at the edges. But by replacing the face pad with a 6mm thick one from the HTC Vive, the problem has disappeared and everything is as it should be.
But Pimax knows this is an issue for some People and because of this, the 8K X will have two face pads, one thin and one thicker.
Picture quality and SDE
The SDE is considerably less than the 5K Plus and is well comparable to the HP Reverb. I can still see the SDE, but really only a little bit. The longer I use the 8K Plus, the less I see the SDE. You have to concentrate very hard to see it.
The sharpness is definitely better than with the 5K Plus. The picture is also much clearer and cleaner. Colors are either the same on both or better on the 8K Plus. In some games, the 8K Plus even comes close to the HP reverb in terms of sharpness. This is for example the case with No mans sky (at least for me).
But for that I have to set the resolution in Steam to 4000 x 3300 pixels (Normal FOV), which is about 175 procent supersampling. But thanks to brainwarp no problem at 72 Hz.
The Performance is in most cases comparable to the 5K Plus. Only in Elite Dangerous I need smart smoothing to have no jerking. With the 5K Plus I didn’t need smart smoothing. But now I only noticed this in Elite and not in any other game.
The funny thing is that both glasses need a super sampling of at least 150 percent to have a really sharp picture. So if you stick to the 1440 p input signal, both are blurred in about the same way. In Elite Dangerous you can see this most clearly. I always had to set the HMD quality to 1.5 to be satisfied. So I am curious how the 8K X will look like
Tracking (Steam VR Tracking, Lighthouse 1.0 and HTC Vive Wands 1.0)
In the beginning I had problems with the 8K Plus while tracking, because I was still using the pitool version .144. The controllers just disappeared after a few minutes. I had to restart everything completely and then disappear again and again.
Then I switched to the current pitool .259 and see there since about 2 days the tracking works fine. No more disappearing of the controllers. I am so glad that i can use room scale vr again
I love the 8K Plus more than anything else and I am very happy about the decision to buy it. I’ve had a few HMDs like the HTC Vive, Samsung Odyssey Plus, Oculus Go, HP Reverb, but none comes close to the 8K Plus. The combination of very good picture quality, close to 0 SDE and the unique FOV makes the 8K Plus the best HMD you can buy at the moment. When the 8K X comes out, that will of course change, but then the 8K Plus will be at least the second best HMD. I will definitely get the 8K X as soon as it is available, no matter how long it takes.
I would like to take this opportunity to thank every single one of the over 6000 backers who made the foundation of Pimax possible in 2016. Without every single one of them we would not be where we are now. Of course there have been delays and problems from pimax but we must not forget what they gave us: a VR headet with HIGH FOV for us consumers. Without pimax we would have to be satisfied with 110 degrees standard FOV or in the best case with 135 degrees Fov of the Valve Index. Or we would have to spend a lot of money and buy a Star VR One or an XTAL, for several times the price to have the same virtual reality experience. I can’t go back to 110 degrees FOV, it’s just not possible anymore.
It feels so much better with the Pimax FOV. I am loving it
Pimax moves with the 8K X to XTAL 8K level for only one sixth of the price of the XTAL 8K, you should never forget that!
Of course the price of the 8K X is not very cheap but when I think about everthing, it’ s worth every cent.
So let’s keep supporting Pimax as long as we can.
At least i need the continuing existens of Pimax and i hope that is for most people the case.
With this little review I want to thank Pimax, the community and of course every single one of the over 6000 backers. Without every single one of you I would not be able to enjoy virtual reality as I do every single day now. It makes my life so much better
With that beeing said, i wish you all the best!
With best regards
