[Resolved] I want to know the compatibility of the A321neo vr.

[Guilhermme Antonio]

Hello everyone at fslabs, it's great to have voices in msfs! I want to buy the a321neo, but a friend of mine who has the 321ceo told me that he can't use it with the VR glasses or Quest3! So before I buy it, I want to know if this is a known problem for you! It's the 321neo and it's compatible with Quest3. Thank you very much.

[Guilhermme Antonio]

Well said, Luck Hall!
I’m not looking for liveries or anything like that — what I really want is feedback from users who have already purchased the products for MSFS.
I’m personally unsure if the product is compatible with the Quest3 VR headset. So far, no responses! I’ve already opened a ticket, and just now I started a topic here on the forum. Later on, I also asked in existing threads.

I’ve been a long-time FSLabs customer, but their support has been disappointing. I remember it used to be quite similar in the past. Seems like time has passed, but things haven’t changed.

Sorry for the rant. 

[Norman Blackburn]

Whilst some of us on the team have VR, my understanding is that none of us have the Quest 3 the same as you.  

[Guilhermme Antonio]

I don't understand! If I'm asking about compatibility with the VR Quest, it's because I have one and use it in my daily life! And if it's compatible with the VR, I'll buy it, if not, I'll wait for a compatible one to come out.

[Norman Blackburn]

Hi Guilhermme,

You have a VR Quest.

We do not.

How are we able to say if it is compatable with it?  

Does the product work in VR - a few of us have used it and it has worked but does that mean it works the same way as you want it to be - I simply don't know!  There may however be other users of it here.

If you run VD with your quest 3 it's fine, and on level with any other airliner on the market. I cant go into great detail as I'm mainly using my crystal light.

And you may not need VD but that's what was fine with me. So why I mentioned it

Hello @Stuart Sheppard, so a friend of mine bought the 321ceo and when he installs the 321ceo, he can't open it, and not only him, but all the other planes, that is, the glasses stop working because of an error in OpenXR. That's why I have a question. With Crystal, don't you use OpenXR?

Sounds like your friend either has issues with his headset or system

 

On my Crystal I use Pimaxx play

[Scott Harmes]

I also use the A321 CEO in VR (Pimax Crystal) and have done so successfully since release.  I haven't tried the NEO in VR yet, but I can't imagine it will work any differently in VR than the CEO.  The Crystal uses Pimax XR, but it can also use OpenXR or Steam VR in MSFS.

[Ahmad Hajjo]

I have the Neo and use it Only in VR with Quest 3 with no problems. I Only hope fsl will update in the future for better performance

[Alfredo Terrero]

Flown the CEO with steamvr (valve index) and works great.

[david arboleda]

I tried but performance is not very good the DLLs it uses blocks the openxrtool not allowing me to update the settings , even worse when is running in the background i cannot open at all the openxr so i have uninstalled  for now i have open a ticket about it

I have same issue with openxr it’s sad because openxr is a usefull tool.

[Lefteris Kalamaras]

Hello guys-

check to see if you have the OpenXR-Toolkit installed in your Windows apps. Apparently, it's installed as part of some VR headset software companions

(Thanks @Alessandro Spigolon for the find).

As soon as I installed that, my VR stopped working properly.

Once I removed it, my VR worked fine again.

From the OpenXR-Toolkit web site:

AS OF 2024, SUPPORT FOR OPENXR TOOLKIT IS DISCONTINUED. THERE IS NO NEW DEVELOPMENT AND NO TECH SUPPORT OF ANY SORT. THE DEVELOPER DOES NOT RECOMMEND TO INSTALL/USE OPENXR TOOLKIT, AS IT IS KNOWN TO CAUSE ISSUES WITH MANY OF THE NEWER GAMES RELEASED IN SINCE 2024.

but for oculus users the companion app is needed in order to modified settings and reduce some GPU load , i been trying with 2024 and works fine with ifly and fenix which both use external software to run , but the fslabs one blocks the companion tool 

[Ben Lim]

What’s the best way setup the Quest controllers with the A321neo? 
 

i remember reading that in MSFS 2024 you can’t use the controller hatswitch to rotate knobs which is strange.

Not sure why but I have also ran into this issue starting today. Does anyone have any recommendations? I can't use OpenXR with the FSLabs installed. I reinstalled MSFS, Windows to make sure I followed the same sequence. New install + PimaxPlay + OpenXR toolkit = will not load. I figure the the OpenXR is what the problem is... 

Uninstalling the FSL CC solved this. Now I'm met with the difficult decision of OpenXR vs having FSL!

Update

[Lefteris Kalamaras]

Please look at my reply above and check if you have OpenXR Toolkit installed. If so, uninstall it and things should go back to normal. That software is outdated and should no longer be used, according to its own developer.

I understand, no worries!

It's the only way many of us (majority of VR users) are able to enjoy VR even though it is now unsupported. Sad that both can't work together.

I guess I'm out of luck guys, enjoy your A32X I'll watch from the sidelines!

[paolo pini]

I also have another problem with the 321neo. I use pimax crystal and it can happen that I have to restart the pimax software but only with the 321 every time I do it, it sends the whole sim to ctd, sometimes even the pc. I use practically every plane of flight simulator pay and only with this one it happens.

that is not the reason as i mention before is the fslabs external application , fenix and ifly works perfectly fine with companion tool 

[Lefteris Kalamaras]

David,

*have you tried* closing that tool?

[paolo pini]

I would like to add that I do not use openxr toolkit but the pimax system itself. I tried again with fenix and ifly which have external tools but with them, even if I restart the pimax play software, nothing happens while with fslabs if I do it, either pimax play stops working not restarting the vr anymore, or it blocks the whole simulator up to the ctd sending vram and gpu into 100% overload

[Lefteris Kalamaras]

Paolo-

do me a favor and check if it's installed in your system - Windows Settings -> Installed Apps.

if you mean openxr toolkit, I already tell you no, I formatted the PC and in any case I had already uninstalled it a year ago and never reinstalled it.

[Lefteris Kalamaras]

Paolo,

can you open a ticket with support@flightsimlabs.com - I'd love to take a look at the Pimax software. I don't know how much we can do, but we can give it a try. (We've already tried communicating with them - the level of interest on their support team is... oh well.)

Paolo,

Puoi aprire un ticket a support@flightsimlabs.com? Mi piacerebbe dare un'occhiata al software Pimax. Non so quanto possiamo fare, ma possiamo provare. (Abbiamo già provato a comunicare con loro: il livello di interesse del loro team di supporto è... vabbè.)

 

yes of course and thank you for the support. unfortunately pimax play is really bad as a software, pimax support is even worse. while we are at it, I would also like to point out that always in vr, the mouse pointer is offset compared to some keys on the overhead and on the fmc, through fslabs software I tried to change the clickspots but without results.

 

[Ron Hoffmann]

Hello! After uninstall OpenXR Toolkit i have the same bug!

[Lefteris Kalamaras]

(I answered you on the other thread).

[Marco DeSanctis]

Hello, I have the same issue - just bought the FS Labs A321Neo and now I'm unable to use VR in MSFS2020

I have a Quest 3, with OpenXR Toolkit which is quite important in MSFS2020 to enable foveated rendering.

I'm happy to support you in diagnosing the issue, if possible, because I only fly in VR and I'm not prepared to give it up

Should I open a ticket?

[Lefteris Kalamaras]

Hello Marco-

we have an open ticket with Pimax (who are using the same toolkit) - they are trying to figure this one out as it's their code that fails with something in the FSL Control Center logic.

I will chase them again as it's been about two weeks now.

[Robert Mathiowetz]

I'm having the same issue. Quest Pro w/ Virtual Desktop, the OpenXR Toolkit will not run with the FS Labs Neo software installed. Don't have this issue with other 3rd party install (PMDG, Fenix, Just Flight, IniBuilds, A2A, to name a few) run it fine. Unfortunately had to uninstall the A321Neo for now since I use dynamic eye tracking with the OpenXR Toolkit. Once you have a really great running VR setup there's just no going back. Just thought I would bring to your attention. Thanks.

[Lefteris Kalamaras]

Hi Robert,

we have repeated this request to Pimax and they are now trying to sort out the issue by bringing us in touch with a member of their software testing team. I remain hopeful that they will resolve their issue, but having not written the OpenXR software, we can't really debug what it is in there that is causing it to crash - so we depend on them to assist.

Thank you for bringing this to our attention!

Thanks for looking after this. 
 

For those who are interested, I have found a workaround. I’m new here so hopefully I’m not breaking any rules, if so feel free to remove my post 😉

First and foremost, I have set the FSLabs control center as disabled in exe.xml

This re-enables VR in MSFS.

Before loading the A21N, you just have to launch the control center manually with the -NOTIFY parameter. Give it 30 seconds to connect to MSFS before loading the flight.

You can do this from the cmdline

C:\FlightSimLabs\ControlCenter\FSLControlCenter.exe -NOTIFY

or create a shortcut similar to the one in the image.

Hope it helps those like me who want to enjoy this beautiful bird in VR 👍

[Lefteris Kalamaras]

Wow - that's a great find, Marco. Thanks for it - I'll forward it to Pimax.

I try! But now i have "FsLabs data not loaded" Why its so complicated to fly this aircraft? Controll Center is running! The other stuff or other aircraft works all fine?

Thx for help and Greetings

sometimes the control center takes a bit to connect to MSFS and if it happens after the plane has loaded, you get the FsLabs data not loaded message.

Just restart the flight and it should work

[Ron Hoffmann]

Where can i see in the Controll Center that is connected with MSFS2024? 

I change "false" to "true" in that line on exe.mxl? 

<Launch.Addon>
    <Name>FSL Control Center</Name>
    <Disabled>True</Disabled>
    <Path>J:\FsLabs\ControlCenter\FSLControlCenter.exe</Path>
    <CommandLine>-NOTIFY</CommandLine>
  </Launch.Addon>

But when i disable the Controll Center there, its not working in that aircraft!

Nothing works! Always FsLabs Data not Loaded! I give up, since i bought this aircraft i cant fly this Neo in VR!

Ron,

Thats hardly surprising when you are changing files.  

Control Center MUST be running before loading the A321.   Either starting in exe.xml or started by you.  If it isn't running then of course things won't work. 

As mentioned above by Marco, start MSFS.  Since you have disabled Control Center you must start it manually and BEFORE selecting the A321.

U know when u change it from false to true its Normaly that the Control Center  isn‘t starting.  Let dem on False then u don‘t have these Problems

The idea is to work around the Pimax bug with OpenXR - it's not for general use anyway.

Idk how! When its disabled in exe.mxl, than its disabled! When i open that Controll Center its always "FsLabs Data not loaded" in the screens. In 2d its working all, but not in vr for pimax!

Assuming you installed Control Center in the same place as before, once you have started MSFS - but not started the NEO - open J:\FsLabs\ControlCenter\ and then find FSLControlCenter.exe.  Double click it.

Once it is running load the FSL aircraft.

Okay thx for all this support, but my next question is, can i see the control center is connected and is running in taskbar?? 

I do all this steps, but dont see its running! 

[Norman Blackburn]

Ìf you have launched Control Center it will show in the taskbar (or the tray if you have had it sent there).  There is nothing to show its connected as its passive.

Here you can see mine on the task bar.
