DCS now supports OpenXR natively

[markturner1960]

How does this (3Dmigoto) work alongside using DCS native openXR and the startup shortcut? I have never tried this mod, and dont want to mess with my working very nicely now install......Can I simply follow the instrcution for the "with OpenXR" version, start the mod via the window and then run DCS via the edited shortcut?

Not sure if you saw my other post, but one of my issues that added to the confusion was that I never really had pure OpenXR mode. Due to a DLL that I forgot to delete OpenXR could not launch and DCS fell back to OpenVR, which in turn used SteamVR. So check the DCS log if it actually says OpenXR for you. Just another thing to consider. While I still don't feel the performance in pure FPS is better, OpenXR seems to have lower latency for me compared to native Oculus. So perhaps you would get the "smoother feeling" you noticed in SteamVR, but without the jitter if you run OpenXR?

Well, I've never installed OpenXR.  Would you suggest I try it?

YMMV, but first, which hmd are you using?

always off, perf hit for no gain that i notice...

very well, there is a small perf hit, depending on the options you choose, but it also has perf fixes  as well as others... yes just follow the instructions

for clarity i dont use it any more, mainly because I no longer use ground shadows, and i dont use reprojection/motion smoothing any more 

which is what causes the rotor artifacts

Thanks! People do not understand computer (or anything for the matter) acronym.

it's not that they don't understand it's just the Three Letter Anacronym is overloaded...

As you need to use the OpenXR version and launch it using an injector before DCS it's totally safe. In fact I sometime forgot to launch it before DCS and so have to restart DCS because mod was not active...

if you use the AH64 or the Mi24 I added some option I found usefull for them: enlightening of mi24 map or disabling of TADSS overlay in IHADSS. Plus the fix for NVG for all planes, or the NS430 for the Mi24. Plus the removal of awfull reflexions in VR. And if course all the other features.

I begin to wonder if the Taz1004's excellent clear glass mod works with bladed wings or not. Ah, better check it myself when I have time.

Since DCS native support for OpenXR was introduced, I reverted back to OB 2.8.  Unfortunately, running the sim with PimaxXR 0.3.0 and OXRTK 1.2.4, I started to have "convergence" issues and stutters as soon as I would start moving my head.  Reverting back to use Opencomposite and PXR 0.2.8 and OXRTK 1.2.1 made the issues go away.

What I labeled as "convergence" issue was causing the image to be blurry, slightly out of focus.  It could also be a slight de-synch between the right and left images.

As for the stutters, they were appearing just at the start of a head movement, one or twice, and then go away.  My frametimes both for CPU and GPU were well below 16.7ms, not even close.

I have the 60hz / 75hz Pimax 8KX (older) model and run the HMD at 60hz.  I do not use motion re-projection and my resolution is 4k native.  Sorry, I did not have the reflex to save my dcs.log file.

@mbucchia, could this be related only to the older 8KX?

How do I force seated mode with OpenXR running? With OpenXR, DCS is running in standing mode so I have a chaperone grid infront of my desk.

@HoneyBadger Bind VR re-center in UI Layer to a button .

But that doesn't get rid of the chaperone grid and Steam doesn't let you turn it off (not that I want to anyway considering I need it for standing VR).

As stated use Open VR Advanced Settings and you can disable it. I use SteamVR (Valve Index user) with no chaperone grid since a long time.

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 was having exactly the same thing with the built in OpenXR (inverted and 180 view), it was one of the reasons I went back to using OpenComposite.

I have a HP Reverb G2 on Windows 11.  OXR runs DCS perfectly as a standalone.   I am unable to get OXR to run via SteamVR.  I have added the .DLL, changed SteamVR setttings- developer advanced to use OXR, and added the launch parameters via copy/paste that work in the standalone shortcut.   I also verified that I am using the beta version via the version number in the lower left of the opening screen.  
 

net: I cannot get the G2 SteamVR to run OXR and I am out of luck.  
 

since this is a Beta is there someplace I can send logs?   The OXR version is highly motivating to help get his going in Steam when it goes GA

It sounds to me that you are trying to use OpenComposite ("added the DLL") with the SteamVR OpenXR runtime, which is totally unnecessary. 

If you want to use OpenXR via SteamVR, don't use OpenComposite at all, just see post 1 and 2 on this thread, run the game with --force_OpenXR while you have OpenXR set in SteamVR developer settings (which you seem to have gotten right already).

[BuzzJob]

Edit:  replaced dll, restarted.   The visual difference is there, so I am sure it’s running now.  In standalone, CTRL-F2 works.  It does not in Steam.  I will check logs to validate.

Second Edit:  VISUALIZER (Main): LAUNCH IN VR OpenXR: Windows Mixed Reality

I really appreciate the help and kudos to you for a brilliant enhancement!

@HoneyBadger Is your chaperone set to be forced to always on? Why? It should only activate if you come to close to the borders.

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 sharper for the same FPS though

Curious what GPU VRAM utilization y'all are seeing?

I thought I'd read that OXR would make it's settings based on the amount of RAM the GPU had.

I have a 16GB 6900XT yet, the OXR toolkit shows it using roughly 7-8GB. Why so underutilized?

I think of SteamVR as a platform, even though it was initially conceived with OpenVR, it now supports various VR runtimes (OpenVR, OpenXR, Oculus).

I sometimes saw as high as 23.1 GB with my 4090 (Apache/Marianas), I think the number at least partially depends on your resolution and graphic settings.

I'm not sure if you are using SteamVR or not, but here are my settings to have no Grid.

 

Also I set the Transparency for Color and Play Area Floor Color all the way to the left.

 

Hope that helps.
