DCS now supports OpenXR natively

[Redlinebuzz]

Apologies for being stupid, I have no idea what VR Runtime I am using, all I know is that when I start DCS the Oculus app starts, I go to the OcukusDebugTool, Force ASW Off then ON, and everything is honkey dorey, But when I do this in the Multi Threading version my framerate locks to 40 (Rift S) as it does in the non MT version, but looking at the scenery it's a mess.

I have looked through the various release notes to see if this is listed as a known issue but couldn't find anything, thankfully the non MT version still works magnificently, am I alone and do I need to look into these different runtimes or should I just wait for a fix?

Any help appreciated, I did search before asking.

Halp - most recent update in last week or two broke native openXR without steamVR - now the game is forcing steamVR to start.  This is open beta I'm talking about.  Can't go even one update without VR being broken again.  I've had to stop and troubleshoot the last like 3 updates in a row.  FYI I am using a varjo aero and had the aero set to only use openxr and then I launch the DCS MT exe from shortcut with the --force_steam_VR in the shortcut.   Steam asks me for confirmation on the extension when I launch it - is this being accepted correctly?

Then it launches the game in 2D mode and not in VR like it used to pre-patch and it also opens SteamVR at this moment, which of course reports a HMD problem since openVR is disabled in the varjo.  Thoughts?

Try adding  --force_OpenXR

Its not broke, it's as it was and should be. Use entry:

"..... :\DCS World OpenBeta\bin\DCS.exe" --force_enable_VR --force_OpenXR

for ST version to have OXR. You dont need SteamVR for this.

Negative - neither of these did anything, either with MT shortcut or with steam command extension, still launches in 2D mode, still launches steamVR.   Also the enablde VR headset IS checked inside settings of game.

Since you're Steam Version... maybe try those command line options here from the list of games in Library, launch options.

  I am launching it from short cut for the Multi-threaded exe.  OpenXR and Varjo Aero do not work in native mode anymore.  It opens steamVR every single time and tries to force openVR mode, even with openvr turned off in the varjo.  It was only the last open beta patch that broke it....

To reiterate:

1.  I don't have any extra programs, just varjo base, steam, and DCS.

2.  DFR is on, vsync is off, motion prediction is off

All of you guys running the game in SteamVR mode are living with higher latency and lower frames - native OpenXR was BUTTER last patch and now I can't get it to work again.

I'm getting the black screen (aero) when forcing openxr, seems it only works if i disable the openxr toolkit.

This is my first full run through with dcs in general and i've never set openxr kit settings like turbo mode with dcs (with msfs yes).  Is the actual reason for the black screen motion prediction being set to on in the aero panel settings perhaps (need to try that later if so)?

have you tried recentering the screen

I have yes, in fact when its "black" in the headset, on the actual pc 2d screen i dont see anything, but the mouse can become trapped in the area where the screen should be.

Have you tried the single thread version?

Might be similar to an issue I had... I have since gone back to ST mode.

On Varjo, DCS forces the use of Quad Views rendering, which is incompatible with OpenXR Toolkit.

You need to use Release Initial release 0.0.1 · mbucchia/OpenXR-InstanceExtensionsWrapper (github.com) if you want to force disabling Quad Views and use OpenXR Toolkit. @BIGNEWY please please please can disabling Varjo quad views just be an option of the game already? It was before OpenXR (via command line). This should be a trivial change to make.

Alternatively, if you are looking for high-performance, you can ditch OpenXR Toolkit and use Home · mbucchia/Varjo-Foveated Wiki (github.com) instead to get eye-tracked foveated rendering. This is not compatible with OpenXR Toolkit, you have to choose between the two.

Thanks, this is really helpful in my situation..  I shall try later today, as nothing else before knowing this worked

Has been out for a while so I'm a bit lost with the latest updates

I'm trying to get the foveated OXR to run on OB version.

Question, do we not need to set bin-mt on the start thread anymore?

I cannot get it to work with that added. Only get a white screen and I can hear the music, and the varjo screen is black.

If I dont use it, then it works, but the fps is really low compared to what I had before. I have removed the wrapper, installed the fovated msi 0.1 and added the 0.2.

I'm not running OX toolkit. I see that I have quad view so that should be ok also.

That should be it... or am I missing someting?

[F19_CoNa]

After a reboot and setting it to "D:\Eagle Dynamics\DCS World OpenBeta\bin-mt\DCS.exe" --force_enable_VR --force_OpenXR it finally worked again

However the 2d screen is not quad view. Should/must it be?

Also, how can I verify that foveated is working?

A few questions i'm wondering, does doing either of these break msfs + openxr toolkit ability?  I guess also, not easily possible to switch between method 1 and foveated to try each out, short of uninstalling and retesting (dcs)?

If using option b and just the foveated option, is there some way to view the fps inside the aero (as you can with openxr toolkit)?

It shouldn't break other apps. There was an update "Varjo-Foveate 0.2.0" that fixes some issues with Unreal apps, but no known issue since.

For OpenXR Toolkit, you can use the per-app activation/deactivation in the desktop app to disable it for a specific game.

You can leave Varjo-Foveated installed while having InstanceExtensionsWrapper, the latter will disable the former. 

The only thing you need to truly uninstall is InstanceExtensionsWrapper. Because the way this works, it has to be inserted in a very special way (unlike the other 2). This is why it's so important that ED provides an option to disable quad views rather than this horrible hack. Or at least they need to follow OpenXR standard and query the output of `xrEnumerateViewConfigurations()`, which they seem to ignore today.

Ive tried open XR, getting lots of warping when I use motion reprojection frustratingly because it is running quite smoothly. I've deleted everything and repaired dcs world (full repair) as I want to revert to steam VR. But SteamVR no longer runs with DCS. Just shuts down when DCS launches and Open XR is still running. I only use the multithreading version of DCS now.

Does anyone know how i can fix this? thanks

If using MR make sure you're NOT also using over prediction reduction aka shaking reduction, found in the oxr toolkit.

Sorry probably didn't make things clear. I'm desperately trying to get rid of open XR and want to go back to using steam VR for DCS but nothing I seem to do accomplishes this. I have deleted OpenXR numerous times, It just comes back when I run DCS, Steam VR shuts down but DCS just runs on Open XR. I've just tried removing Mixed reality and steam VR and reinstalling but i'm still having the same thing, can anyone advise.  

[speed-of-heat]

AFAIK if you are using the MT option you are functionally forced to OpenXR (at least at the moment)

Only ST version works with OXR or OVR (SteamVR), MT only OXR.

Hi,

After some experimentation, it seems if I run DCS with OpenXR, then my MEta Quest Pro second controller (left hand) isn't recognized.

If I run DCS with Oculus API (not forcing OpenXR) then I can see both controllers. If I run MT version, then only one controller shows up (further proof that OpenXR messes with second controller).

I hope that this can be addressed.

Thank you

I keep trying to launch with forced openxr and openvr turned off in Aero and it tries to open steamvr EVERY SINGLE TIME and then loads the game in 2D.  I am using shortcut settings for the MT process like this:

"C:\Program Files (x86)\Steam\steamapps\common\DCSWorld\bin-mt\DCS.exe" --force_enable_VR --force_OpenXR

Just basically ignores it and launches in 2d anyways.  The steamvr pops with all sorts of errors for why steamvr isn't on or w/e.   Why is it trying to use steamvr?????  Anyone?

I have foveated turned off, openvr turned off(aero settings0, and vsync also turned off.  According to everyone else's comments and posts this is the settings everyone is using... yet it still tries and fails to use steamvr.  Why?
