Coming from a G-2 the image is really dramatically changed for me, I don't see the overlap and it's sharp all the way to the edges, find I'm not moving my head as much to look around and see things.  No longer have to look directly to spot contacts.  Seeing aircraft in a fight is way easier, especially below, can pick up motion quite well.  Things look so good the game is showing its age more outside the tree band, can't set it out any further.  4090 on 7800 3DX max settings even shadows, no AA, running 120 hz set locked to half it's butter smooth res set 100%.  Only aberration is ghosting on the leading and trailing edges on the wings when the take off roll gains speed on a concrete or PSP runway.  If I run 90 or 72 hz I get bad artifacts on the prop and lot's of ghosting and judder at full res, not quite making it to peak FPS there anyway.  Really don't want to back down on res.

 

 

 

You should be able to run 72hz w/o motion reprojection with about the same settings, and not see those artifacts. Motion smoothing works extremely well for me in MSFS using steamvr with the crystal..

[[CPT]Crunch]

I do see continuous artifacts in the prop at 72 fixed, and looking toward the sun drops my fps substantially.  It doesn't feel smooth like 120 locked to 60 along with worse artifacts at 72.  Should say my IPD is 68 by opticians measurement, but I'm preferring the unit set closer to 71, just seems overall better.  My guess is higher ones IPD the less problems you'll experience with a light.  Been looking for the overlap bands and just don't see them, see no difference in clarity from center to edge.  That said the G-2 center seemed a bit crisper and sharper, but I'm betting its the prescription lens inserts that are the difference.

Thats strange, you should see less artifacts w/o motion reprojection on, then with it on, since a fake frame isnt being injected. You may want to verify that smart smoothing/lock to half framerate is off in both Pimaxplay and PimaxXR if you want to try w/o reprojection. I tried IL2 as you have it setup and it looks pretty good and fairly smooth, but at 72hz w/o reprojection I see no artifacts and its very smooth for me.

Got it running great at 90 fps, had to back the res down to 3000x and ensure clouds aren't at extreme.  It wasn't the sun, it was clouds, in this headset they chug harder than shadows.  That's basically the only setting I needed to reduce, no extreme clouds, everything else can be run max, also never use canopy reflections as I despise them. 

 

Can get away with 4 FSAA or 2 MSAA but it actually looks better all off.  No need to push it back up with NIS or such, looks great, but I desperately need inserts, been using glasses, just too clear for my old eyes and it's noticeable.  Basically made sure all repro was off and image set high than set in game res all through the XR toolkit inside the game. 

 

Does SSAO or HDR work in Pimax?  They worth messing with?  I've found my new ride.

Think I was seeing those artifacts because all the WMR stuff was still installed.

Good Deal! At 90hz, your frame time limit should be around 11.1ms. At 72hz it should be around 13.8ms. Below are the settings I use, and I also have the same CPU/GPU as you. You should be able to run render resolution at 72hz (4312x5100). At 72hz, I typically have a 1-3ms buffer depending upon the map. I'm not too keen on using shadows due to personal preference, but definitely could include them if wanted. MSAA is a big hit and I don't really notice any benefit using it at all. Although  I max out FXAA since there isn't any performance hit at all using it. I don't use any upscaling, but it might be usefull if your using a weaker GPU.

 

HDR brightens the screen a bit but with a small GPU hit, SSAO hits the GPU hard. I didn't see any benefit using either personally. One thing I would recommend is to get the studioform apache strap/spacer kit. It allows you to form the contour and necessary distance of your face to the faceplate. Also, I bought optical inserts from HonsVR. They work perfectly, are very reasonably priced, and pretty quick to ship. I also like that they are magnetically attached as it makes it easy to clean and switch out if somebody else is using your headset.

 

Also, check out the Chiliwili69 post about WMR limiting resolution in steamvr. I dont think it applies if using opencomposite/openxr though..

Yup, first step before even plugging it in was complete comfort pack install, wonder who they used for the initial design, King Kong? 

 

Just got done checking out some 0230 o'dark hundred sorties and ended up cranking local dimming to extreme, very nice.  Picked up on the muzzle flashes and convoys with only the slit lights fairly well in the dark, and the dastardly train daring to run with full head lamp.  Shot up a few but line ups are not easy especially on artillery that goes dark.  Tried popping flares to illuminate, but unfortunately they don't actually work. 

 

Had a Samsung that was nice at night but the clarity is better in this one, judging a concrete runway and the lights on everything look more realistic.  You just see the pin point of the light when pointed at you, no big glow going on.  If they get behind tree's or in the woods the glow doesn't give them away.  In the Samsung you could see the glow for miles, in this set you have to be almost right on them.  But the QMB does have a full moon going, be interesting to see it in full dark, hopefully an area they work on for Korea with illumination flares. 

[[CPT]Crunch]

36.8% firing accuracy in a P-51D, think that speaks volumes on the capability of this headset, ground attack game is way beyond the usual in new uncharted territory.  Only fly the box, the ground wreckers paradise.  Big difference in ability to see targets, judge attack angles, distance, and depth.  All drastically improved.

New pimax play software out with a built in upscaler. Can anyone report back if it works good? I got the original crystal so its not available to us folks..

 

 

[[CPT]Crunch]

Works extremely well, solid 90 fps for me, no dips at all.  Roughly runs 3100x3800 per eye.  Only issue is spotting is ultra difficult at medium range, planes nearly disappear at 7-8 km till about 2.5.  

 

Need time to figure out s solution for that, until then it's back to the old 90 fps and backing res to around .72 on the scale.

I'm sure glad I'm not trying to order a Crystal light right now. My lens are producing a weird pixelation thing outside the sweet spot, Pimax tech support said it was due to defective lens and would be sending me out a new set, that was almost a month ago now. I asked when they would ship, the response sounded like they are waiting for more lens to be manufactured and sent to their warehouse, so no timeline was given. Has anyone been able to get a new order headset delivered in a timely manner?

[c19580]

I sent my headset back after at least 40 emails of nonsense and am waiting for a replacement.

 

I was told it would take “a little while longer” which I did not appreciate as an acceptable response. I was also told that they were trying to fulfill new orders.

 

Beyond frustrating communication… hoping that the replacement headset is without quality issues.

Well, I guess it's not like this is a new thing with Pimax, we've all heard a read that their customer support is and always has been woefully lacking. I can't believe they told you they are trying to fill new orders rather than supporting existing customers with defective headsets.

Fair comment and agree, I went in eyes wide open, so although it’s still frustrating I’m not surprised and will stick it out.

 

The part that got me going was exactly what you pointed out. They should take care of customers they shipped defective headsets to before they take on new customers.

 

Back to the Quest 3 for now and honestly, can’t say I feel like it’s been much of downgrade at all.

[franjo]

I have about 130 hours into IL2.  Mostly with trackir and a bit with the quest 3.  Recently picked up a pimax crystal and running it with open composite.  Pimax play is set to 1.0, and 90hz.  Holding 90fps and absolutely blown away by the clarity.  I even turned off AA in the game.  The smoothness and quality is absolutely mind blowing.  I’m hooked again lol.  I can’t wait to put some more time into this.

 

[Chilli_40]

I have a question: Pimax's, tech support determined my lens are defective and are supposed to be replacing them as I had said in an earlier post, well other than the fact that it's coming up on 2 months with still no replacement lens. My question is, my headset has the local dimming feature, is this feature produced by the lens or is it an internal component that does it? If it's created by the lens how will I even know that the replacement lens are the correct ones? Currently if I try and fly at night it's like looking through a really fogged up windshield. Not saying that I don't trust Pimax, but I don't trust Pimax.

I was informed by Pimax that their US warehouse (not sure where you are) would be restocked on Sept 15th, although this was after the previously said late August…

Great, I guess what they're saying is they have no idea when they'll restock. They told me a week ago they were shipping mine, even provided a tracking number, but all that amounted to was the label had been created, nothing had shipped!

Try vertical offset 1.8+ for each eye, what it does is render the equal value in pixels per eye such as 3536x3538 when set to 82% resolution while running the same amount of pixels as when it was set at 75% res at 3234x3826 per eye without an offset.  I'm getting a noticeably better picture using this pumping the maximum pixels my system can deal with, without any issues in a loaded heavy scene.  Either way it's twelve and a half million pixels, sweet spot for my system.  FOV is pretty much unaffected, if I pull the lens up so my eye bottoms out, I can see the top black straight edge, but its not visible in normal use.  Pretty much can crank a 10% increase in resolution while pumping near the same amount pixels.

Thanks, that works well. Brought my render resolution from 4312x5104 to 4312x4314. Picture looks the same and saves about 1.5ms or so on the GPU frametime...

[c19580]

I received my replacement PCL after having to send the first one back due to significant blurriness in the center and what appeared like stereoscopic issues preventing sharp images when both eyes were open.

 

The replacement is “slightly” better but is still not sharp with both eyes open and have an overall blurry image. I’ve had to set the physical IPD to 58mm and use the in-game IPD offset of max 30% and it’s “better” than before but still prevents me from playing competitively.

 

After going back to the Quest 3 for a month, I realize that while the resolution of the PCL is better by far, the experience is much worse. After playing combat box for a couple of hours, I was getting jumped a lot more and had difficulty with spotting.

 

Spending some time on discord, it seems like MANY users are reporting blurriness issues with the PCL, so this is definitely an issue and not sure if it’s quality related or simply a defect of the PCL.

 

Before I decide to just give up entirely, a few questions to try to salvage the situation:

- Does anyone know of VR image calibration software, such as an eye chart or some other tool?

- I’ve struggled to figure out how the IPD offset works in Pimax Play. Does anyone know how this works?

- Things look significantly smaller with the PCL than with the Quest 3. Planes are tiny in size and very difficult to spot. Is there a way to make things look bigger like I perceive the Quest 3 to be?

It's for the 8K but the principles are the same.  I don't have an issue with mine, moving them either way horizontally messes it up, does not improve anything. 

 

Should be some tools in the steam store, no longer have steam myself.

 

If you use the openXR toolkit with all the adjustments there's a world scaling slider, there are three of us all using some type of crystal and all pretty much use 120%, in the pimax you need to restart the game to see it change, the G-2 would change live as you slid the values scale.  You'll never hit a tree and they appear to be taller, much easier to fly lower, but it doesn't actually change the FOV one bit.  Think it has something to do with perception of focal point.

Nope, don't have controllers either, but you can still play around with the settings and see if it makes a difference.  I found setting the vertical offsets +1.8 makes a huge advantage in visuals as far as resolution and sharpness for me at no cost.  At minimum his video give you a basic understanding of what the offsets do.  Think pimax needs some sort of manual, not much for documentation.

My sweet spot is +3 vertical offset for both eyes and now set at 4312x4628. I used the testhmd app and adjusted it thru software with the pimax experiance home app. My vertical FOV was too high at default, but now everything is square. It gave me a little better visuals also...

please forgive my ignorance but since the native resolution is 2800 x 2800, what actually happens when you set it ( assume openxr toolkit?) to 4312 x 4628?

 

a top end system already struggles at max settings at native resolution, and the native resolution is already very good, so trying to understand the purpose of setting an even higher resolution.

To account for barrel distortion.  A render quality setting of 1.00 in pimax play, and default vertical/horizontal fov, produces a resolution of 4312x5100 thats suppose to negate barrel distortion. I keep the render quality setting at 1.00 and move the vertical offset so that lower and upper portion of my fov are equally aligned. That makes a 4312x4628 resolution based on how my face looks into the HMD. A higher resolution creates a crisper image. I'm running a 4090 and get around 10-11ms on GPU at 72hz on most maps. I have about 2-3ms of buffer room.

 

If you got the testhmd app, look at the eyechart at 5m while increasing the render resolution. You will see the difference.

 

attached are 3 screenshots of the crystal at different resolution. 2888x3100, 4312x4628 and 5604x6016.

 

Below is of the crystal at 4312x4628, pico4 w/usb connection at 3840x3840, and crystal at 2888x3100.

In the case of Pico4 (with XR2 Gen1 chip) the limit bandwidth of 150Mbps would be the real limiting factor. What freq did you use for Pico4, 72Hz or 90Hz?

 

I was comparing here the Quest3 (with XR2 Gen2 and 200Mbps limit) with the PCL and for low resolutions (2644x3128 per eye, so 16.5 Million pixels) the Quest3 gave better visuals.

Wow, I see the PCL still has some potential beyond 40 Million pixels.

4312x4628x2= 40 Million pixels, even a 4090 can not mantain that at 90Hz.

DFR or any other upscaling technique needs to be used as you do with the Toolkit and the 72Hz mode.

5604x6016x2=67.5 Million pixels, this is out of the range of any GPU in the near future.

Sure,

 

I use the testhmd vFOV test to get the alignment and would keep the render resolution at 1.0 in pimax play. You move the 2 red dots vertically until they are outside your FOV. On my default offset setting, the top red dot would hit the top of the screen well before the bottom dot did. I used the pimax experience app to move the vertical offset down so that both dots disappeared at the same time. You could also use the vertical offset in the pimax play app also, but you would have to take the headset off to make the changes.

 

You can see the resolution in steamvr or pimaxXR. I got the new pimaxplay 1.32 beta, so I deleted pimaxxr because its not needed.

 

I have no idea if quest 3 controllers would work.

I'm running 4312x4628 at 72hz daily on this thing in IL2 w/no ffr/dfr and maintain between 10-11ms with the 4090. I think 11ms is the limit for 90hz..

I'm running 4312x4628 at 72hz daily on this thing in IL2 w/no ffr/dfr and maintain between 10-11ms with the 4090

After further research. Pimax may be using an asymmetric FOV which is a better approximation of human vision. So the default offset setting may be by design.
