Am a little undecided yet whether I should return my 5k+ loaner or buy it with plan G. (Particularly as I have a good 5k+ without any issues).
Am currently using the 144 Hz mode for BeatSaber&Co, think games like this won’t be so much fun with 75 Hz. Fortunately the 8kX can also run at 120 Hz in upscaled mode.
So a question to people who have (or had) a 5k and a 8k+: How would you judge the clarity of the 8k+ vs the 5k+? Is the image of the 8k+ as least as clear as the 5k+? And does the scaler impose any latencies or is there no noticable difference between 5k+ and 8k+ in that regard?
Thanks for your feedback!
P.S.: Bonus question: Can two Pimax HMDs + four controllers + two gen1 basestations be used on the same PC? 2xHMD+4xcontroller+2xBS and two PCs should work in any case, right?
I can give you my 2 cents to it, just need to get back home and spend a bit of family time before going into detail.
For me, the answer is 8K X in dual mode has more clarity than 5K+.
@Sweviver said that showing macro photos
and also @VoodooDE told of that comparing 8K+ with index
However there is a limitation : both have High end PC
I9 9900K/S + 2080 TI
I still use my 5k+, the clarity is a little bit better for me. 8k+ is back in the box.
Sorry, it got late last night and me tired faster as I would have liked.
I like my 8k+, for me its a bit harder to dial in a perfect sweet spot then with the 5k+ I had a bit of room left to the lowest IPD (I have about 62) with the 5k+, with the 8k+ it seems that I need to go down all the way and still think that the lens center is a bit further rout (have not managed to actually measure it - will do that today).
So in terms of clarity - its two folded in my eyes. The image of the 5k+ is very crisp and clear, but the SDE “cuts” that image noticeably, especially compared to the 8k+. The 8k+ scaler adds something that I positively would compare to a film grain or softening - its not that crisp Image the 5k+ delivers. BUT do i get more information out of the 5k+? I don’t think I do. I guess its pretty much on one level. What the 5k+ buts in on clarity is partially reduced by its SDE. The 8K+ on the other hand has no noticeable SDE while playing and so does not have that information missing in the picture, but stuff is softer or maybe a little fuzzy (SDE you can see it if focusing on it, but not anywhere as prominent as with the 5k). So in the end its quite the same, but the 8K+ SDE less images does something to me that makes the VR Worlds come more a live for me. I will try and do the shots of Alyx hands, where we tried to read the stuff on the chips or the colors of the resistors (left hand). From what I did see I would guess that the SDE cuts greater holes in the image information then the 8k+.
The Image of the 8k+ does improve with super sampling but you need some HP to get that running smoother - Alyx worked like a charm for me (but I do have a good PC Setup I guess , also a I9 9900K/S + 2080 TI )
Edit: some links you might consider to check up
my mini review, scroll down, there are some Images
a comparison thread
8k+ in Alyx (Hand on the wall through the lense shot)
The through-the-lens clarity on the 8K+ is quite good, even with the softening. What’s truly impressive is the effort that went into the models in HL:A. At a glance, that circuit board looks real. I can’t wait to see how it looks on an 8KX!
I think there might be more polygons in that circuit board than in an entire level in an early game, like Quake.
Dear @PimaxUSA and @SweViver - have you made some low IPD tests?
It seems that with the 8k+ this has changed for me - either its build tolerance or something that is different due to the new screens. Its just like its a few mm less on the lowest IPD possible or the lens sweet spot further out. But could be anything else also (Comfort Kit).
Yeah its really amazing, it could be a Circuit Board Build um Simulator rather then a game object - really cool! In that thread I also found that even if the images looked close, some fine details could be better perceived with the 8k+, like the feet of the IC or the bend of the resistors connector, the others seemd to smooth that out more then the 8k+ which is kind of strange since its scaling the image.
My guess is that it’s the Comfort Kit. Does the problem get reduced if you mash the HMD into your face? I assume you only have 1 foam pad. I think this is why the second thinner pad is now being included.
Yes that could be part of the issue - I might try to remove it and see what happens if i swap them. but its generally like if I took a look with just one eye and look a bit more outward then normal its perfect. I could get that in the 5k+ and still have room dialing down to 60 (so 62 fit quite good). In the 8k+ I am at 60mm IPD dialed in and still have that effect. In the 5k I noticed that the center was moving out of my focus also for lower vales of IPD, which I cant reproduce on the 8K+ , there I go as low as it can.
Thanks you guys for your opinions!
Think I will buy the 5k+, that way I also have a safety net in case I might have to send the 8kX back (well, I don’t hope so, e.g. my first 5k+ was nonfunctional though, so it is possible). Think the price Pimax is asking for buying the loaner is not far from the resell value, so in case the 8kX is the perfect solution for all use cases, I could simply sell the 5k+ later.
My IPD is 58.8 and I’m able to achieve clarity the same as my 5k+ on the 8k+. The only thing for me at least on the comfort kit thick foam I have to tighten an extra 1mm or so. The MAS makes a nice difference in this regard because you have more pressure and it’s almost impossible to orient the headset at a slight angle.
Also I’d point out that the soft foam does make it easier to orient the headset at a slight vertical angle when the facial pressure should instead be directly towards the face.
I only return my 5K+ cause Pimax can’t give me a non-defective one.
I have the same experience with my 8k+ and replaced the face foam with a thinner one to get it more comfortable.
Hm, if the 5k+ turns out to be better for fast paced games and the vision kit and MAS are really comfortable must-haves, then the decision to keep the 5k+ could become more expensive than initially anticipated…
So also the IPD experience is “more original”? Then I definetly need to try that. What did you use, is that a vive foam?
I noticed immediately after the first few minutes of gamplay with the 8k+ that something is not “right” for me, and i am happy now with it. I use the same foam with 5k+ to get as near to the lense as possible.
Yes, its a 6mm face foam for htc vive .
Thanks I will try that!
I also had the feeling that the top Comfort kit foam pushes the HMD in an unusual position since my forehead seems a bit large ( I noticed you removed yours).
But didn’t extend on that. But I think I really should.
Its a really a picky thing to get the “perfect” position and it really makes a large difference.
As far as I understood they use another foam for the 8kX now? Would be interesting whether the Vision kits that can be bought individually all have that new foam now or the one that came with the 8k+?
Pimax has stated that the new comfort kits will come with 2 pieces of foam: 1 regular (what they have been shipping) and a new thinner foam. I’m not sure if this covers the separately purchasable CK or only the one that comes with the 8KX (and possibly other newly-ordered headsets).
