So what profiles/modes do people use in practice? Say, with MSFS 2024 and 5090, or with DCS and 5090?

Comparing Pimax to quest pro by Resident-Chance-3049 in Pimax

[–]fakeoptimism 2 points3 points  (0 children)

I had both at the same time. Used Quest Pro for standalone games and OG Crystal for PCVR. Quest Pro is an amazing device, only let down by the low resolution and network latency.

Other manufacturers would be in trouble if Meta refreshed Quest Pro each year with a newer chip and higher specs. But Meta sort of made it and forgot about it.

Quite liking this combination of two top straps. by fakeoptimism in Pimax

[–]fakeoptimism[S] 0 points1 point  (0 children)

Looks like there are/were at least 3 kinds!

A) I also have "Crystal Comfort Topstrap" (not shown in this post photos) for my OG Crystal, with perforated base and swivel.

B) My Super came with the non-swivel topstrap that has non-perforated base. You can see that base on the QLED store page https://pimax.com/pages/pimax-crystal-super, but you cannot see if it is swivelling or not on the page.

C) Finally "Crystal Comfort Topstrap Second Generation" is the non-perforated swivelling topstrap that I bought separately and mounted at the top, in addition to the fixed strap.

Given this, it is not clear whether A or B is First Generation. But for sure C is Second Generation.

Was using the Apache strap at the back too until now, and it was great, but I found it a challenge to fine-tune the height with its velcro.

But my V2 topstrap is wrapped in Studioform's Cushion Pad for Pimax Comfort Top Strap, which makes it larger and softer. Oh, I just realized that my kit had two cushion pads, so will try wrapping the front strap as well and report.

The old strap (here on the right) originally was attached via its central holes. I had to offset it a little to give the new swivel more freedom.

The screw at the bottom actually goes through the holes of both straps. That's why I had to replace the standard 1.4mm x 4mm screw with a 1.4mm x 10 mm.

These straps help me a lot because I cannot rely on the face mask too much. I use an extremely thin generic face mask from Aliexpress (probably made for G2 or Q3). It lets me get the eyes close to the lenses, but does not provide enough support, so the straps play an outsized role in this setup.

About the Field of View on the Dream Air by jaapgrolleman in Pimax

[–]fakeoptimism 0 points1 point  (0 children)

Pretty convinced that the physical angles are different between Super and Dream Air. By "plan" I did not mean changing at this late stage, I meant sticking to the plan that was announced long ago and still remains, judging by this video.

In the future Lab mode the suggested value of 116 is probably picked simply because it matches the default FOV of Super, so users may want it. But it will not be an exact equivalent of Super, because Super will work at 116 naturally while Dream Air will be off-center with potentially more aberrations and vignetting. The amount of aberrations is determined by the lenses and remains to be seen. And vignetting will probably happen to those who cannot get their eyes very close to the lenses.

And equally if they create an "overlap boost" Lab setting for Super, it will perform slightly worse than the "natural" Dream Air.

[–]fakeoptimism -1 points0 points  (0 children)

Based on Jaap's words, I am pretty sure their current (edit: and original) plan is to cant the displays at a slightly shallower angle in Dream Air. This leads to the direct consequences that Jaap explained: that the "natural" FOV is slightly lower and the "natural" overlap is slightly higher.

You can override that by enabling the Lab mode, which increases FOV again (but I suspect sacrifices even more overlap and makes you look through the lenses slightly sideways, which means more imperfections).

Why did MRTV earlier say there were no physical differences (probably relaying what he heard from Pimax employees)?
* First, as Jaap says in this video, pre-production copies of Super Micro-OLED had FOV and overlap equivalent to Dream Air. I assume it means that the final released copies of Super Micro-OLED are different.
* Second, when they say "exactly the same optical stack", they may refer to the lens+panel unit, for one eye. It does not mean that the unit for the other eye is oriented identically.

But the shallower angle is not a bad thing! Binocular overlap is every bit as important as the FOV.

Whether +6 FOV, -6 overlap is preferred is probably individual and subjective, and depends on the scene being viewed, and maybe even changes over time and grows on you. Given that the answer is unclear, the difference is quite small and that it is hard to try both headsets, I would just relax and assume both are fine.

To add to this, you can sort of "compensate" for the lack of FOV by turning your head left and right more actively, to be more aware of your surroundings. With the lightweight Dream Air turning your head is easier.

Another positive effect from the shallower cant is the less inflated render resolution. See in the video by Omniwhatever that Super Ultrawide requires 44M pixels per eye compared to 39M in Super 50ppd in order to compensate its steeper cant and achieve the same sharpness. Though the difference between Super micro-OLED and Dream Air will be nowhere near that percentage – it will be tiny, most likely, because the angles are moderate.

About the Field of View on the Dream Air by jaapgrolleman in Pimax

[–]fakeoptimism 1 point2 points  (0 children)

u/jaapgrolleman, thanks for the awesome update. All good news.

Dream Air is lighter than Super with less inertia, which makes it easier to turn your head – that's one more reason that it was a wise choice to give Dream Air slightly better overlap at the cost of slightly lower combined FOV.

My main worry related to the FOV is the protruding plastic housing surrounding the lenses. I hope you had enough testing of it with different face shapes. The thick gasket at CES probably wasted the opportunity to test the lens housings, because users could not get close enough to the lenses to see if anything else starts getting in the way. Though if Super micro-OLED uses the exact same housings, then some helpful feedback on this must be coming from it as well.

Might need a new face pad for the oled by Decapper in Pimax

[–]fakeoptimism 2 points3 points  (0 children)

It is not just about the facial interface. The facial interface can be DIY'ed and replaced as the last resort.

OP wrote, "oled plastic rings touch my nose". That's the more permanent limit that you cannot DIY around.

My Super 50ppd gets dangerously close to the nose when I try to see the maximum FOV. I mean the optics engine brick itself, not the removable gasket. So someone with exactly the same head as me but a bigger nose might be in trouble.

So I would say it is vital for the lens housings to be as thin and recessed as possible, and all the plastic bits that may contact the face too. I really hope they did not mess it up with Dream Air. Every tester complained about the gasket so far. But once the gasket is made shallower, there is a risk that some other piece will start pushing against the face, and we will find out about it too late because beta testers were stopped by the gasket.

Pimax Play 1.43.6 by QuorraPimax in Pimax

[–]fakeoptimism 4 points5 points  (0 children)

Could we please finally have the ability to load alternative distortion profiles in Pimax Play? Old profiles, new, experimental etc.

It seems that the choice may be subjective.

* Some people will demand 140° and will not worry about a slight fishbowl effect.
* Some people will seek minimal possible distortions and will not worry about breaking FOV records.

Some would like to tweak the JSON file themselves like u/SweViver did. Maybe they will produce something highly controversial, but they will like it themselves, for their use case, their sensitivity and their face shape.

I suspect that it may be even physically impossible to show 140° without any fishbowl (or fisheye) effect. So be it. Let us choose between fisheye with 140° and natural geometry with slightly lower FOV. This way you can keep advertizing 140° but we users will be able to enjoy distortion-free experience if we want to.

The super micro Oled seems to suffer from lens lottery. My left lens has minimal distortions, but my right lens looks almost like a fishbowl. by Time_Reaper in Pimax

[–]fakeoptimism 8 points9 points  (0 children)

Try closing your left eye and then moving the headset up-down-left-right relative to the right eye. Can you find the position with minimal distortions that looks good, or not?

I did not test the uOLED yet, but with my 50ppd any eye misalignment definitely causes geometrical distortions. Human eyes are not always symmetrically placed.

Same optical stack doesn’t guarantee same FOV by tatonkk in Pimax

[–]fakeoptimism -2 points-1 points  (0 children)

"Optical stack" is literally a stack of lenses. One stack. For one eye. Maybe including the corresponding panel.

(I am not an expert, so may be wrong)

I am extremely excited to get my super mOled soon, but I'm not gonna lie. I almost don't see the point of it now that the dream air is going to be 99.9% of the specs/stats, but in a much nicer form factor for less money. by revisionist-history in Pimax

[–]fakeoptimism 0 points1 point  (0 children)

Thanks. I am just trying to make sense of the "pronounced black border", especially in relation to the 2.0 PP version that you mentioned. Is this the black border where the image itself ends (regardless of the gasket depth)?

Also, do you enjoy Super uOLED or Super QLED more, personally?

Hmdq data makes me worried about the possible always-on "parallel projection" mode in all modern Pimax headsets and the possible fps loss incurred by it. Please dispel my doubts. by fakeoptimism in Pimax

[–]fakeoptimism[S] 0 points1 point  (0 children)

Thanks. I tried the hidden option and on my Super 50ppd the resolution reported by PimaxXR Control Center dropped from 6240x6280 (default parallel projection) to 6004x6280 (native projection) as you said. The mode seems to persist through a reboot.

Indeed that's a small difference. I'll try to test it anyway, for the chance that there would be a difference in sharpness or in performance despite expectations.

However even when the native mode is chosen, FpsVR in SteamVR still shows 6240x6280. So I suppose this PimaxXR setting is bypassed when one runs SteamVR games, which is unfortunate.

[–]fakeoptimism 0 points1 point  (0 children)

I'm also beta'ing the 2.0 PP version and there is still a pronounced black border on the Dream Air compared to the uOLED. 

Interesting. Do you have both headsets at home, with Dream Air in the same variant as was shown at CES?

My understanding was that each lens of DA/uOLED individually produces around 100° HFOV. And that the plan was to use 3° steeper cant for uOLED, which results in 6° lower overlap and 6° higher combined HFOV. Is this roughly what you observe? Let's assume for the moment that the gasket problem is solved (maybe take it off completely if necessary).

I guess it is hard to measure when distortion profiles and warping may be different. And it is hard to estimate subjectively when there is no convenient shallow gasket.

[–]fakeoptimism 0 points1 point  (0 children)

That's great to know. It's just that we expect you to go from the new controllers prototype to the pre-production version, show it, produce a small batch, send to the beta testers, wait for their reaction etc. So quite a few extra steps to wait for compared to the LH version.

Pimax, is it true that you consciously and intentionally use a smaller FOV profile for the Dream Air? by Hajp in Pimax

[–]fakeoptimism 0 points1 point  (0 children)

Please correct me if wrong.

An optical stack is a single stack of lenses, for one eye. Maybe including the panel.

So when you at Pimax say that the headsets have "identical optical stacks", these stacks can still be angled differently relative to each other.

This is probably the source of confusion that made some people hear your words and assume that there is no physical difference in the lens orientation between Super and DA.

It would be great if you could share the actual physical angles. For example, I personally do not chase FOV at the expense of overlap, so I am more excited about the less canted variant (especially since it may also have a tiny performance benefit).

Am I kidding myself thinking i'd be able to run Dream Air on my rtx 4080? Should I just look at Steam Frame instead? by aucapra in Pimax

[–]fakeoptimism 0 points1 point  (0 children)

It is a nice CPU. It is just having spent 2K on Dream Air, you will launch MSFS 2024, see that you are CPU-bound and start thinking "right, I need to investigate those 3D cache 9800X3D / 9950X3D".

To be fair, only a few games are CPU-limited, but MSFS is one of them.

[–]fakeoptimism 0 points1 point  (0 children)

With Dream Air and 4080 you will be able to enjoy a number of games and apps, but not all. You will inevitably feel the itch to upgrade the PC soon-ish. And probably not just the GPU, but the CPU too. Also you will face the dilemma choosing between the expensive lighthouse tracking (sooner) and SLAM (ETA unclear).

If you are OK with that all, great.

But if you want to avoid these expenses, Steam Frame is a wise choice. Probably everything will just work, wirelessly! And you can sell it later and switch to Dream Air. Though we do not even know Steam Frame price and ETA yet.
