What?
Wrong GPU, that is why I am not testing performance or anything releated with that.
You don’t know what yo are talking about, and that’s ok, just don’t discredit something because you don’t understand the tech.
“look who he is friends”
WTF is that supposed to mean? Are you a stalker?
My friends are my friends, and guess what? They are VR Dev tech people, so yeah we know what VR is on every aspect QUITE well.
Enough of that kind of senseless BS comments that I had on R/pimax.

Thank you Axacuatl.
You get it.
FYI I can see the other lens/screen when I look on the side, but also in my peripherical vision when looking straight, Like with the HMD on, well fitted.
But as we know “user experience varies from one to another” and that is why VR is so hard to make!
I liked this review and took it for what it is: a very technical review, going indepth into spotted issues.
That’s what I’m always looking for when I must buy something without being able to test it, because I know I am very picky about issues, I often see issues that I haven’t heard about from regular user reviews, so I like to have indepth and very critical reviews like that and then I know what critics I should take or leave (knowing what will matter or not for my personal use and personal sensitivity to a given flaw).
Interesting points I noted from this review:
-
pimax HMD can be used without using pitool, by directly launching steam (but you lose any pitool setting of course, like fov adjustments but also other settings like render resolution etc.). Has anyone tried that ? May be interesting to check if there is any perfomance gain from skipping pitool.
-
large part of vertical fov wasted. He mentionned that when you move the HMD in order to try to see the panel border (or just past the limit you can see when wearing the HMD in “normal position”) you can see plenty of hidden pixels are used. While this is something I already noticed on my rift, on the pimax with which GPU saving is more critical to get good performance (fps/SS & other game options affecting visual quality) it may be nice idea to have vertical FOV options like we already have for horizontal FOV. I mean if we can save some GPU by fine tuning the vertical FOV so that it displays just what is required to not see the black past visible displayed area (on the panels), which depends on your head shape (having your eyeballs more or less close to the lenses), then it may be worth having the ability to make this fine tuning.
-
left eye can see right panel (and vice versa): this reminds me a girl from the Berlin meetup who was reporting about an annoying “bar” (?) she was seeing in the middle of her FOV. Would both be related ? (and possibly affecting only specific IPD)
-
170 FOV usefulness: the nice thing I see from this 170 FOV target even if it can be considered as missed goal is I think is what allowed for such a large sweetspot. The huge sweetspot is a (positive) consequence of the very large lenses, and the large lenses was required because of the 170 FOV initial target. If the FOV target had been 140-150 the lenses would have been shrinked down, and so would have been the sweetspot too.

No, you won’t lose settings. With pitool you can configure settings and the Pimax SteamVR driver then uses these settings, with or without the pitool running. So you’ll only need to run pitool if you want to change a setting.
In theory this won’t matter much. Pitool really isn’t much more than a piece of software that can change settings, by forwarding the new settings to both the HMD and via a config file to the SteamVR driver. It just connects to the ‘piservice’ via a TCP/IP port, forwards the settings over that port to the service, which in turn communicates the settings to the HMD.

Oh ok, I see then thanks. So not launching pitool interface doesn’t mean you would go around pimax driver. So no performance gain to expect from doing this indeed.

Thank you Neel. We need more users whom are not going to run with nonsense.
Both the RoV & TH review like this one had way too much negativity from users here due to over hype of excessive bubblegum reviews showing the headset running well due to having folks whom have a strong level of experience tweaking things to work.
To put it simply folks need to simply pass on reviews that don’t speak to them instead of starting inquisitions.
Both @oscar_rov & @Pumcy reviews were great for their intended audiences be it Really technical or for the lay user; this review is no different.

Many people are doing the mistake to think they going to be plugged in the Matrix once the Pimax on the head.
Looks like being a dev doesnt keep you away from this.
I just think Oliver was really disappointed his Pimax wasn’t the “dream” HMD etc…
My problem with the review is the incongruity of it all. For instance:
High FoV vs. Low FoV = he chooses low FoV.
(or put another way 90 degrees no distortion vs 150 degrees small distortion = he chooses 90)
Large Sweet Spot vs. Small Sweet Spot = he chooses Small Sweet Spot.
Cannot discern distant objects vs. Can discern distant object = he chooses no need for distant objects
Cannot read small text vs. able to read small text = he chooses no need for small text
Excessive god rays vs minimal god rays = he chooses excessive god rays
Highly noticeable SDE vs. minimal SDE = he chooses Highly noticeable SDE
No modules upcoming vs. modules for eye tracking, hand tracking etc. = he chooses none
Wide FoV and higher PPD experience in games = didn’t bother to test any games
This constitutes most of the fundamentals of any HMD.
He then declares Pimax is a “failure”. I can’t get my head around the incongruity of the whole thing. Just bizarre.

Just wanted to throw a little history into the mix.
Remember CRT TV’s? If you grew up watching CRT TV’s then you spent a lot of time watching a device that had severe “edge distortion”. They masked the last couple of inches of the edges of the CRT to hide where the image starts to curve. In the later days of the tech, they came up with expensive “flat screen” CRT’s that were actually flat and showed almost to the edge. But we’ve had “edge distortion” since we’ve had TV’s, they’ve just done different things to hide it from the consumers!
Have fun!

Strangely I don’t remember seeing that on my…oh god what was it called…IYamee? Vision CRT
Of course not! Why do you think your picture has that plastic edge? The CRT goes up into the plastic quite a ways… Unless your “Vision CRT” was one of the later ones with a flat screen. Those only hid around .5" to 1" of the CRT. We all took these for granted and never noticed it!

Ah ok just thought that was over/underscan

Lol, “under/over scan” were techniques that were developed to deal with the “edge distortion”!
Edit: if you “underscan” your TV, then the only picture that you can see is on the flat part of the CRT, it no longer extends to the curved edge: now you no longer have edge distortion…

haha yeah, ok. it was easy to remove so never really bothered about it. Wish you could just push the Pimax distortion off the lenses/panels rather than make the tape bigger

I’ll never find the post again, but I read somewhere that the displays for all of our current headsets are actually practicing a technique like this already. Apparently, if you don’t “overscan” the picture (make the actual image larger than you can see) then the consumer will actually see the edges, due to the shape of our eyeballs.

I think as always folks like yourself are over analyzing due to the bubblegum impression reviews.
Pimax said wide fov comes with compromises. As a developer you need to understand these compromises to create work arounds that can work within the limitations of the tech.
First gen lcd were not thst great compared to today. Pimax wide fov headset is a first gen wide fov headset. It fails on many levels because of this. But this shouldn’t be confused with meaning it’s totally a fail.
A developer technical review helps other developers know the limits of a tech so they can work within those limits & use tricks so that current limits can be masked.
We know so far from “impressions” thus far the pimax headsets are a success in terms of gamers & the like. But if your looking for truer 1:1 success on a technical side it’s not there yet. Like og starvr vs the as of yet unreleased starvr one. I personally would like to read @OlivierJT & @oscar_rov technical reviews of StarVR One; especially on analyzing the claimed horizintal FoV vs what it actually might be.

Hidden by the bezel & the black area on the tube if removed. just don’t touch the wires lol
Simply solution make the lens slightly bigger & cover the edge where it tapers off.
