DCS now supports OpenXR natively

New revelation for me today.

I was not aware, that you could run SteamVR and have OpenXR Toolkit too.

So It's possible to have SteamVR motion reprojection (currently superior to openxr one regarding artefacts) and CAS sharpener/ FFR shader from OpenXR Toolkit.

I'm currently testing 60Hz Reverb G2 mode with SteamVR motion reprojection (so 30FPS) and CAS / FFR shader

 

EDIT: The OpenXR runtime is still much scharper for the same FPS though

 

Very interesting!   Would love to see your settings.  I am also using 60Hz w OXR/SteamVR and impressed with how smooth things are.  I am not as far as you are.

Hi, just a quick question: could the new ".dll" from DCS together with the start parameters work with other games and openxr too? I think of trying this with Dirt Rally 2 which is also a favorite Sim of mine and you're forced to use the OpenComposite...

I don’t believe you could make another game have native support for OpenXR by copying the dll. You would still need to use OpenComposite as far as I know.

I haven't seen a need for motion smoothing/reprojection while running at 60Hz.

it's already smooth

For this config to run:

- open SteamVR, go to options->developer and set SteamVR as the used runtime for OpenXR

- have OpenXR Toolkit installed

- use  "--force_enable_VR --force_OpenXR" params when runing DCS (like you would, when using the new native OpenXR implementation in DCS)

- turn on reprojection via WMR for SteamVR menu

- set your OXRTK preferences as usual

The game resolution is based on SteamVR options (not the OpenXR Tools for Windows Mixed Reality app)

Anyway, for me, the best result is still to use 60Hz, no reprojection, OpenXR with Toolkit and try to hit that 60FPS for smoothness.

It's smooth if you can manage to get that 60FPS, but on RTX 3060 and Reverb G2, that's not an easy feat.

I finally had the time to update the OpenXR toolkit this afternoon. And I see a higher FPS but I can't get the menu to show up by pressing CTRL F2. I uninstalled the older version as I thought I read it was recommended.

Any ideas? Thanks!!!

Since I moved to native OpenXR (with OpenXR Toolkit), I noticed that sometimes when starting the game my view inside HMD (Reverb G2) is upside down and facing back (the desktop mirror is ok). Usually changing game resolution in options or changing render scale in OpenXR tools for WMR fixes this. Today I noticed one more thing - even if I manage to have right picture orientation, the HMD mask (shader) is upside down.

Is anyone having this?

I had got exactly the  same issue as you experienced this morning and I think it is OpenXR related issue .

I have been able to run DCS in VR via the short-cut of the program + command line since the update and the program has been running ok apart from being not that sharp in comparison with the image quality before the update . Everytime  I check DCS log and the log always indicates the program runs in OpenVR.

However this morning for some reason I got " image upside down " which could not be corrected  by " center button" . I check the log and log reveals the program runs "  LAUNCH IN VR OpenXR: Windows Mixed Reality". It has never happened to me before, interesting !

I wonder if the "--openXR "line could be deleted for the time being .

BTW I have to run the "command line " method when the toolkit set to be the safe mode , otherwise DCS crushes.

I think the upside down and backwards problem was determined to be a problem with XRNeckSafer - assuming you are using that.  To fix that problem select "Deactivate XRNS OpenXR API Layer" from the OpenXR menu in necksafer

To fix that problem start XRNS first, then  DCS.exe --force_enable_VR --force_OpenXR. When in the DCS hangar put on headset and then press the XRNS/DCS center button.

yes, thank you.. I had to do both (start xrns first and make the change i mentioned above), of course ymmv:)

Why would you use SteamVR with a WMR headset though?

As mentioned it provides yet another option, SteamVR motion reprojection with OpenXR and the toolkit options.

Is that not available without SteamVR? Sorry, I haven't played around with it much yet. I got OpenXR working with OpenComposite, but didn't do any teaks beyond that.

The WMR OpenXR reprojection and SteamVR reprojection are subtly different. Some prefer the SteamVR version which can now use the OpenXR runtime since we have native OpenXR support in DCS.

I need some help here when ever I try to go to a mp server when I get to the  fly button and click it DCS hangs up with just a desert scene no crash log or anything. I have done a fast repair& slow.  tried the different shortcuts. deleted open composit reinstalled it .  This last patch and hotfix has tanked my DCS. I have motion reprojection off in open xr and the toolkit(latest version}.  My system amd x5800x3d  32gig ram ssd's  3060 and hp reverb g2 ver1. Works fine for SP

I'm also seeing something similar.  With DCS Settings->VR->"enable HMD Mask" checked, if I'm running DCS via OpenXR (launch parameters " --force_enable_VR   --force_OpenXR") with either Windows Mixed Reality or SteamVR set as the OpenXR runtime, the HMD Mask is upside down compared to running DCS VR via OpenComposite or SteamVR OpenVR.

Oh ok. It just seems like using SteamVR (with a WMR headset) would mitigate any advantage since you have to add another application in the chain. Granted, that's getting outside of my expertise. Unless I'm mistaken though (which could very well be), WMR for SteamVR is still required? But then maybe it's not any different than having/needing OpenXR for WMR...

If it is only in MP server mission that you have this issue, it might be related to your client not being ''pure''.  Do you have any mods running that breaks IC?  There is an icon that is either green (OK IC) or red (IC broken) on top of the server list.  The other issue could be that you are missing a required/compulsory module to access the mission.  This should show in the bottom left corner in the server description when the specific server you want is selected.

Might be a folder/file permission issue. If you installed the server to say X:\ProgramFiles x86\... it or other necessary folder could be write protected.

The problem started after the openxr update and hotfix had zero problems with MP servers before that. Even our squadron servers are hanging up on me. Getting ready to break out my Quest2 and try it with their runtime and see if it will work or not.  No red shield or IC fail. I can enter the sever pick my slot then the briefing screen click fly. Then it hangs on what ever the scenery happens to be at the time

Have a look at your log if you can notice any error at the end.  Since you say that single player works fine, then this is weird.

Post a new bug with your dcs.log, dxdiag output and as much details as possible.

I had a very similar issue with a G1, it started with Half Life Alyx and after 10 mins or so one eye of the headset would go grey then come back intermittently. It turned out to be the cable and HP replaced it under warranty. 
Touching wood, the same G1 is working perfectly with DCS and native OpenXR support.

Hi.

Just a brief feedback to my problem with a flickering headset. It seems going back to an older driver (AMD Adrenalin 22.5) solved this and some other problems with GoogleEarthVR.

So its not always good to follow the recommendation of installing the newest driver. Adrenalin 22.3 worked best for me, but this does not support my current GPU anymore.

@BIGNEWYA smaller bug with native OpenXR - VR controller grip/aim/laser pointer angle is wrong - there's another report here which is probably native OpenXR due to the timing:

Both that OP and I are using Oculus headsets (them: Rift S; me: Quest 2 or Quest Pro). For me, the controller angle is fine when using OpenComposite or the Oculus API - it's *only* wrong when using `--force_OpenXR`
