First off - what is your resolution setting in the Pimax Play app? Have you altered that resolution (up or down) set by the Pimax Play app by using openXR Tookit while ingame with that apps system menu - Override resolution function? 100%-200% resolution... I guess that is refering to your multiplier for the focused area. I don't use the Quadview companion app, so I set my multiplier by manually alterering a config file (your way is probably easier, but I found my "gold setting" right away so I won't play around with it anymore anyway. Not for now..)So in the settings file the multiplier is set by, like say 1.0 is the same as 100%, and 0.5 is the same as 50% and so on. So here are my settings that gives me 90 fps: In Pimax Play -Maximum resolution. BUT - that gives a very high resolution as starting point for all the multipliers - 4312x5102 or something crazy high like that. So in OpenXR Tookit, while in game, I enter its System menu, which is almost all the way to right, one step down to Override resolution - change that to yes, and lower the resolution there to 3800x4497 (or something like that. It is 3800 multiplied by something). That gives lower and in my eyes more realistic starting point. Now you have to restart DCS to make that take effect before seeing any effect of that change. As for changes in the Quadview companion app? None. I don't use it. But I guess that would be the same as setting everything to default in that app. (Not sure though cause I don't use it). So defaults gives me Focus area=1.0 multiplier (equals 100%), out of focus area multiplier is 0.5 (equals 50% in the app) (or I think I actually changed that to 0.4 -40% then--you get the idea). But nothing else is changed. So my in focus area is rendered at 3800x4497 resolution and the out of focus area at 40 (or to) % of that. Also Quadview gives 70% sharpening as default, so I don't change that or use that function in the OpenXR toolkit either. If I was to use 200% for the in focus area then that would make the in focus render at 7600x8994. I don't need that. It just slows the system way too much down even though the in focus area isn't that big part of the picture . And even if lower the out of focus area a lot, I think the difference between in focus and than transition to out focus are would be to apparant. Also- 3800x4497 in the in focus area is pretty clear! I have i9 13900K and RTX 4090.

The beta multi threaded version is now OpenXR so no “— force open XR” is needed. Also if you ran DCS in VR last time and didn’t switch off vr in the in game menus it will start in VR next time too. And in that case you don’t need “force enable VR“ either.

Before playing MSFS you can uncheck the box for Use Quadview in the PimaxXr app, and leave the box for use Eye Tracking checked. But it seems like OpenXr toolkit itself remember different settings for different games correctly.

Not much you need to to in OpenXR Toolkit if you got Quadviews working. Quadviews in itself adds 70% sharpening as default, so don't do any additional in OpenXR Toolkit. But in the OpenXR Toolkit System menu, you can use Override Resolution and set a lower resolution than what your Pimax Play gave you as starting point. I did that. Pimax Play set to Normal(or 1 I think) on thePimax Play Resolution panel gives about 4309x5100 or something. I lowered that with OpenXR toolkit to about 3800x4400 or something like that. So in OpenXR Toolkit don't use FSR/NIS scaling or sharpening, and don't use anything from Foveated rendering in there either. That is now handled by Quadviews. Mind you, I did not change anything withQuadviews with Tallymouse companion app.

Thanks, that is a good guide with pictures and all I posted a copy of your link in the pinned thread about Quad view. But in you setup picture of Tallymouse companion app, only 4% in the peripheral resolution - that seemed low! But I have to check it out

Jaapgrolleman from Pimax posted this link in another thread here, I think it's a good addition to Mbucchia's guide https://pimax.com/quad-views-foveated-rendering-for-pimax-crystal/

Yes. it is really OMG! In my house now I have one HP Reverb G2, one Reverb (G1), one Quest 2, one Pimax 8KX, two Pico 4. And earlier I have had HTC Vive and Vive Pro. Pimax Crystal is the first one I got where I was thinking OMG when I used it the first times - and I still say (or think) OMG when using it. I've been into VR since 2017. What distortions?? I think one of problems with perhaps some of the Youtube influencers reviews is that quite a number of them got the headset pretty early. Even before the final lenses and software even were ready. I know they used plastic lenses for a while in them. Anyway, distortions isn't anything I would worry about now. One thing is the clarity of the picture. But the colors and contrast of the panels! The local dimming! I don't think people talk about these things enough. Also - the sound solution is very good. I'd even say it is better the G2. And the inside out tracking works flawlessly for simming and car games. I have not done any other types of games on it yet. I sit down in my car og aircraft cockpit and it is perfect for that. As for the controllers? I think I have them somewhere around here. Not sure why anyone would use them in DCS. They would probably work well. They are pretty standard, nothing wrong about them, and nothing execeptional either. Just works. Is everything perfect? Nope, and my 50.000 euros home cinema setup isn't either. I can nitpick all day long in that room (well, not really , but I'm sure I could find something), and probably could with the Crystal too. There is always something... Never tried the Varjo Aero. I considered purchasing one now that the prices has come down, since I already got the basestations and controllers (got those for my Pimax 8Kx). But - not sure what that would have to offer making it worth it. The panels are not as good according to those who have both, especially for night time flying and so on. And the FOV isn't either, especially the vertical FOV. And no built in sound solution. But it is supposed to be more comfortable wearing it, and also no batteries is important. I have seen videos of the vertical FOV and that put me off. I suppose I could get used to it. But... the vertical FOV on the Crystal is amazing. And the horisontal is good, way better than Quest 2 and Reverb G2, somewhat better than Pico 4. (But nowhere near my 8KX of course). So.. being more comfortable would be important. But I have a feeling Aeoro will announce an upgrade model of the Aeoro "soon" (meaning the next 6 months) and I can wait and see. Ok, just some random and not so random thought one Thursday morning here. In short - for simming - yeah, the Crystal is OMG. Even more so for iRacing.

I have the Pimax crystal and I think that maybe it is needed to calibrate the eyetracking every time I turn the headset power on. Not sure. But I have noticed that if check the first picture in eye calibration tool, you know where you see those points forming a circle and you can look at them to check calibration, the dot the doesn't move as fast and accurate as it should. But if I then continue through with the eye full calibration and complete it by watching the dot move across the black screen and then then white screen, and afterwards go into the check calibration picture - the dot behaves as it should and go to the posistion I look very fast and reliable. About adjusting resolutions... I think that if you at this point are CPU limitied, then I think maybe there won't be that much fps to gain? I could be wrong though.

First off, thank so much mbucchia!! I can now really enjoy my Pimax Crystal, also got the eyetracking working with the Pimax updates yesterday. I checked a bit with the debug_eye_gaze=1 in the settings.cfg file, and inside DCS I was surprised to see how well eyetracking worked It was a bit to read, but I got working good in the end. Just a question, on the wiki page for advanced instructions it says: and that means in my case, Pimax play application for Crystal in Win 11. Now, for some reason Pimax play doesn't allow you to set your resolution directly, instead it uses terms like Balanced, Maximum and so on, or you can set a number manually like 0.5, 0.75 1.0 ... which then translates to specific resolution in the headset. I set mine at "Maxium" in Pimax Play - which translates to something like 4500x5100 or some crazy high number like that. So, inside OpenXR Toolkit I used the "Overide Resolution" and lowered my resolution to 3800x(something). 3800x4400 ish... close to that anyway. So to my question (took a while ) from the quote above - do I understand it correctly now that the resolution settings in the Quad view configuration file in my case are multiplayers of my resolution value set through OpenXR Toolkit "Override resolution" which I have set at 3800x4400 ? Not sure if I make myself understood, English is not my native language (- and that means also it takes some time to read through all the instructions and hopefully understand them correctly)

So - are you youtube influencer or is eyetracking really released for the rest of us ??

Thanks for asking My PC: I9 13900K, Asus ROG Strix GeForce RTX 4090 OC, 32 GB RAM@6000Mhz. Resolution - well tried a few different settings, but 3500x4142 I think it was last time I played and checked with OpenXR toolkit. I can not get stable 90fps with that resolution. To get stable 90fps I have to lower the resolution so much - or tune down graphic settings so much - that buying the Crystal would seem a waste of lot of money. I get more than 45fps of course, but since motion reprojection/motion smoothing don't work that well, that doesn't help. I have to turn that off. And so that gives me judder. Which I really really don't like at all. With my Reverb G2 I usually used motion reprojection, which worked better than on the Crystal. And with my Pico 4 (same resolution as G2) with the Virtual Desktop solution I got a crisp picture with more or less stable 72fps (or above) - which the Pico 4headset could lock on at. I really wish Crystal would get a 72fps option like Pico4 has. Then I could get smooth gaming and crystal clear picture with the Crystal. Yeah, I know some people get motion sickness with lower than 90fps but me - nope. I can take it. But below 72.... naaaaaaah... too low. So stable 72 and I am good. So - my problem is - not getting 90 fps stable, and motion smoothing not working good, and 72fps not being an option with the headset. But - that being said - I did a bit of flying and being able to spot ground targets really good (at least compared to my other headsets) was... nice

Thanks, but it seems to be working as it should. Been testing a bit since I got it and the colors and clarity is amazing! Hard to get good performance though. Motion reprojection is not working good.

Thanks! I installed Pimax Play now. I got an error message during that installation pretty quickly... So could choose Retry, Ignore or Abort - the usual Windows way of solving this. So tried Retry a couple of times - that did not work so aborted. Tried again, but ran the Pimax Play installer as administrator - and this time I could almost finnish the setup program, but just before it finnished - another error message - corrupt file, so Retry, Ignore or abort. Just for the heck of it I chose "Retry" and after two times hitting that, it continued.. Now, up until now at least, I have have a very stable system. I use this PC just for gaming and simming, and never had any issues with either Reverb G2 or the Pico 4 on this PC. So, not at good start there with the Pimax setup software. Hopefully it will work correctly in the end. I could launch the Pimax Play software and log into my account. But I have not yet connected the headset, still charging batteries. The software version is the newest on their web page - found here: https://pimax.com/downloads-manuals/ Crossing my fingers now I will know more later this afternoon.

Hi everybody, I'm getting my Pimax Crystal this afternoon. While sitting here waiting for it, I thought I'd better off becoming a little prepared. So I started looking around the Pimax website for set up instructions - which I found. But, in there it shows how to plug the various cables into the right ports, power adapter, usb, display port and so on. BUT - should I not install the Pimax Play software first ?, before plugging anything into my PC? I can see no mention of that in their guide. Well, I did find the Pimax Play software download page, but it doesn't tell if I should install that on my PC first before connecting anything. I already have installed the latest version of OpenXr toolkit (version 1.3.2) on my PC because I've been using it with other headsets. As of now, I have no Pimax software installed on my PC. But I have downloaded PimaxXR and Quadview foveated rendering app - but have not installed any of those yet. Will make sure my headsets starts up "normal" first time, though I understand I need PimaxXR to run DCS without SteamVR's Openxr solution. And I have downloaded Pimax Play (latest release version which is 1.14... something), but not yet installed that either. Latest Beta of DCS MT installed already. Anything else I need to download? What is the correct order for doing things software (and hardware) wise?

1. yes. I do that through VD with DCS beta. I have a shortcut on my desktop for that. I am not at home these days so don’t remember what I put in there. But you also have to edit a value in Windows registry to make it work. I get somewhat higher fps and also crisper visuals by not using SteamVR. 2. Don’t know

It works with multithreading too. In addition to what you have do to start the single thread version, you have to change one value in Windows registry first. Don’t remember the exact location in the registry, but it is there where it states which open XR to use, and you just change that value to “none”. Works like a charm. But, if you play another bar game that use SteamVR, then you have to enter the registry and change it back to none again before launching DCS. I play the multithreaded version with Pico 4 this way, without SteamVR. I get better performance

Can’t answer those questions. But do you have a link to the news about Pico4 and open Xr?

Thinder´s Virtual Desktop picture looks different than yours (and different to the rest of us too probably) because he is not using the right Virtual Desktop program on his PC. He says he downloaded it from Steam and that is not the correct version for Pico 4. The Pico 4 version for installing on your PC is on this webpage for free : https://www.vrdesktop.net/ So, You are not supposed to use both Streaming assistant and Virtual Desktop. Just Virtual desktop. That’s the easy way. Ah, and I see Qcumber already pointed you in the right direction.

My experience with open XR toolkit and Pico 4 is quite opposite. I used Open XR toolkit with my Reverb G2. But disabled it for the Pico 4. Not needed at all. It doesn’t add anything but potential complications on my PC. On a less powerful PCs it might come in handy, yes. But now I am more happy without it.

Colors, local dimming - yep, that is my impression too from reviews - that those are Quest Pro advantages. Didn’t know about the brightness, but might be correct too. I don’t consider that is a problem with the Pico 4 though. But the the Pico 4 has better resolution, - the Quest Pro is about 30% less resolution in total. So Quest Pro should be easier on the PC, but less sharp. I have never tried a Quest Pro so I can’t give my own personal impression about it. Just wanted to correct the info on the Pico 4. I recently read some Facebook post about problems with Pico 4 lenses for some people. You might check that out too if you consider it. Mine are good though.

?? No problem with Pico4. Smooth as butter. Clear picture all over the field og view. Don’t know which posts you are referring to, but to me this is just plain wrong. I upgraded from Reverb G2 to the Pico 4 and I am very happy with that.

The Pico4 is 8000 cheaper… Like I said, the difference is depended on your country. In Norway Quest Pro is over 13.000, and Pico 4 about 5000. Some time ago the Quest Pro was over 18.000 and Pico 4 just over 4000… so.. it changes .

I have the G2, but it is collecting dust after I got the Pico4. Very happy with the Pico4, amazing in DCS. Pancake lenses gives edge to edge clarity. Light weight. 2160x2160 resolution per eye, same as G2. But you need a powerful PC to run it well. The Quest Pro has lower resolution and costs 3-4 times as much - depending on your country.

That is normal when using OpenXR with the Pico4.

Thanks! I will check it out Before the MT update I had with the Pico4 8-10 fps more when using the Oculus runtime than when using the OpenXr through SteamVR. Also the Oculus gave me somewhat crispier/clearer picture. Will test your method later today.
