DCS now supports OpenXR natively

[Hiob]

Hey guys,

I'm a little bit lost with my Valve Index right now. I use it very seldom in the first place and with the new update I'm totally confused.

Could some helpful angel with Index experience give me a step by step guide?

I understood that I need to select OpenXR inside SteamVR as runtime. Apart from that - what do I need to do for an optimal Valve Index - DCS setup?

[VR Flight Guy in PJ Pants]

Okay, so I am going to delete OpenComposite, revert to the original openvr_api.dll

For Pico4, I just start DCS from File Explorer or make a shortcut which force SteamVR in the command line, right?

I tried the method of launching from the VD desktop icon, but it does not seem to go to OpenXR.

So, how would I know that the DCS World is actually running in OpenXR or not? Yes, I notice that OXRTK, DCS.EXE is registered there.

Frankly, this is the best news so far, I was too happy I could not sleep until 02:00

Hi,

I`ve got an issue in the update has broken my DCS to the point i cannot even boot into the menu. It hangs on startup. 

I`m running an 8kx and was perfect 5 mins before I updated. Previously I`m running open composite, open xr and pimax xr. The only thing I ran in openxr toolkit was the ffr wide setting.

I`ve tried different versions of pimax xr, disabling open xr, booting in open xr safe mode, deleting the open composite file, reinstalling it etc. but it will not get past that point. I cannot boot in open xr safe mode as it just hangs also.

Also others having the same

Any pointers?

I sketched up what this changes for Oculus Link users; as for how to use it, mbucchia's comment covers everything on a fresh install; mods/past optimizations can make things *much* more complicated. Virtual Desktop users must use SteamVR or switch to Link/Airlink.

Previous OpenXR user with standalone DCS.
Since updating startup hangs and SteamVR insists on opening which is freaking irritating as I don't want SteamVR.

Was all working perfectly pre the latest patch, now it's totally fubarred and I haven't a clue where to start with this mess.

 

Deleted SteamVR and now DCS does start with OpenXR as it should, hardly ideal though as I need SteamVr for other programs.

Found the culprit.
For some reason in the WMR portal the setting for 'When I open Mixed Reality Portal, automatically start Windows Mixed Reality for SteamVR' had checked itself.

Ok, now i'm confused.

What must i do to use the Pico 4 with Virtual Desktop and Stand Alone DCS to get the best VR Experience?

[AKA_Clutter]

Dumb question.  Do I need to download and install OpenXR.  If so where do I get it?

No; OpenXR is a standard, not a piece of software; however, depending on your headset, you may need to download and install headset-specific software that adds support for OpenXR.

Depending on which headset you have select the openXR runtime and DCS will work without any third party apps. 

Currently we are working on a crash if motion reprojection is being forced on. If you have reprojection on auto or off you will not see the crash. 

 

Tested and it works, still having 90FPS with Reverb G2.

Only I've noticed that gauge textures are horrible and before, they were crystal clear.

Before I was using OpenComponsite, all I've just done is: clean DCS installation directory, update to the last OpenBeta and launch without --force_steamVR

Just posting in case anybody else has this problem too!

I think many of you guys are a bit nervous.

For those who were using OpenComposite prior to yesterday update:

Step 1. depending on your install method:

• System wide installation: you can delete or keep the OpenComposite folder, it would make no difference after you do the next step
• Per game installation: If you were using per game one you should restore openvr_api.dll file, if you dont have a backup you can run a DCS repair

Step 2. Depending of your headset

• SteamVR headsets: go to SteamVR options and make SteamVR the default OpenXR runtime
• Oculus headsets: For Oculus users, go to your PC software options and make Oculus the default OpenXR runtime

Done, you dont need no more, OpenXR Toolkit is just an ADDON to add some features and tweak some settings for OpenXR, its not needed but you can still use it

For any specfic problem with a headset there are dedicated topics here and i think its a better place to ask than a general topic

Have you checked if the settings for pixel density etc. have changed?

[Morphine]

For Varjo Aero and VR/XR-3 users.

Currently the native DCS OpenXR implementation forces the 4-screen Varjo mode ON and there does not appear to be a way to run it in the 2-screen mode (also the DCS VR window no longer shows the 4 screens as before). However, the cursor offset/mis-aligned issue persists in the 4-screen mode thus making OpenXR mostly useless for all Varjo users.

As everyone is reporting, you can still use the OpenComposite .dll replacement to use OpenXR and OpenXR Toolkit, etc.

@mbucchia Can you add this information to your original post so that all the Varjo users don't try to run ED native OpenXR and will have to default to SteamVR for now or OpenComposite .dll?

@BIGNEWY Is there any chance that the offset/mis-aligned cursor issue will be addressed as this has been an issue for over two years even in the previous Native Varjo implementation? Or at a minimum allow users to force a 2-screen OpenXR setting?

Thanks.

check you are not forcing motion reprojection, it creates a crash, a fix will be coming for this. 
If it is not that post in the crash section of the forum with your dcs log we will look for clues

thanks

I don't remember what it was before, but now it's 1.4

Haven't touched a single configuration. Will play around with values. I think I will have to increase some of the textures resolution.

Thanks!

Varjo user here... given the issue with misaligned cursor + no reprojection I reverted to using my varjo through opnVR as I did before the update... i.e use the openvr_api.dll hack with the -force-steamvr command.   Works fine.

If this all looks fine and the layer is not coming up with ctrl-f2, how can you fix that?

Two things, one is in your dcs.log, there should be a line with "INFO    VISUALIZER (Main): LAUNCH IN VR : SteamVR/OpenXR : oculus" and the second is that when you start DCS and land in the main menu, you will be positioned quite high so that you are looking across the wing of the jet in the hangar. From there you simply press your VR recenter button and your height should be set right in front of the menu.

[VR Flight Guy in PJ Pants]

Click on the "DCS World OpenBeta" icon, SteamVR also starts. When the title screen shows (and shakes like crazy, typical SteamVR attraction), DCS World crashes. I check OpenXR line is present on the log and from the crash file, looks like the file GraphicsVista is misbehaving.

Uninstalled OpenXR Toolkit

Check that no WMR reprojection is on

It is Pico4 using VD. 2D version is still running fine.

Any suggestion is welcomed.

I downloaded the OpenXR Tool Kit, how do I get DCS to show in the Tool Kit?

 

On WMR with a G2

[RealDCSpilot]

@VR Flight Guy in PJ Pants @NatoAviator Try to get rid of any additional tweak first. Basically start with vanilla DCS and your VR runtime only. SteamVR with VD (VR Flight Guy) or plain WMR (NatoAviator). This will continue in the next months, because a lot will change. Most of the known tweaks will get old and deprecated.

Game bug:

Nothing I can do about. It does work for certain users though (PimaxXR 0.3.0 works fine for me).

[VR Flight Guy in PJ Pants]

@RealDCSpilot I have cleaned and repaired but it did not work. Let me see what else I can do.

I remove the saved games directory and it still crashes.

No. I see that you have HP Reverb so you have it already :).

It's because we can't use FSR or CAS sharpening without the openXR toolkit.  This OB patch is a downgrade for VR users who were using those tools.

Is there anything that could enable CAS sharpening again?
