Sorted, it is one of the mods in the saved games mod directory. Can figure out which one(s) go wrong.

OpenXR Toolkit seems to have no problem.

Few things that may be useful. With OpenXR supported in the game, you do not need OpenComposite anymore, regardless of what headset you use. The goal of OpenComposite is to bridge OpenVR to OpenX

Released a new version of OpenXR Toolkit 1.2.4, when used with DCS in native OpenXR mode, will let you use WMR reprojection and also Turbo Mode. Quickstart | OpenXR Toolkit (mbucchia.github.io)

@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.

 

Thank you!

Got it working.

Now, I'm trying to figure out how to use my mouse cursor in WMR/OpenXR...

It works fine in 2D, however when I put on the HMD, I lose mouse cursor control...

For anyone using Oculus Rift S, this worked for me. I set Steam VR as my default OpenXR runtime and then started DCS in Steam VR mode.

in the WMR settings, under startup and desktop, change input switches, to be "Manually switch using Windows logo key......."

Those using OpenComposite won't notice much of a difference, since we've been use to the lack of in-game stuttering for some time, but it does mean that any DCS update won't prevent players from using OpenXR as it is now baked in.

 

That is not correct .

I have been playing DCS in VR ( G2 headset) by using OpenComposite for a very long time and the DCS had been running smoothly. However last night I installed the latest patch and DCS just had " million" crash episodes and every time I had to use Task Manager to close the program. I can not even to send out the crash report because the mouse froze.  I wonder whether I should remove the Beta version and re-install the stable version for a period .

I'll apologize as I spoke too soon - I have a habit of doing that, I'm sure some have noticed.

 

There are some issues depending on the headset. Mbucchia, a Microsoft developer who worked/works on OpenXR, appears to be offering his assistance on the matter.

 

As a workaround, in themeantime, you should still be able to use OpenComposite with --force_steamVR

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.

I don’t know what are you talking but for those options and much more you can use OpenXR Toolkit, it has no problem working with last update

Same here....same issues and than i realized it is unplayable because DCS OpenXR doesnt accept Motion Reprojection. Before i had everything smooth anf flawless 70-90fps with G2 and no i cant play - too much stutters and head movement micro stutters unplayable.

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. 

 

Some are angee over this as their troubleshooting methods have included complete re-installs in the past 24 hours...I for one would love to see the bar graph data on downloads over a period of time for the past 2 days that would include the sharp spike in downloads due to re-installs as part of the troubleshooting method. I'm glad that ED remembered to make this post...

I cant even get past the opening menu with my G2 in VR. Freezes after 5-15 seconds. I can still hear my menu music, but totally frozen. 

I have force motion reprojection, or else DCS is way too stuttery with my 3090. Also using OpenXR composite. Tried going back to SteamVR but same crash.

Please fix it soon. We need a HOTFIX pretty please.

What is strange with mod (OpenComposite) I didnt noticed any CTD like now, with OpenXR motion reprojection always on. So tests failed.

Is there a way to manually change the motion repro tool kit setting outside the game to restore it?

Yes, open the toolkit, go into safe mode, it resets everything, fire up the game and reset.

Maybe it is possible with command line https://mbucchia.github.io/OpenXR-Toolkit/cli.html

you can start openXR from toolkit in Safe mode and when you start dcs CTRL+F1+F2+F3 will resest  everything. But on G2 without Motion Reprojection it is unplayable

I seem to have no problem with my G2 without reprojection. Don't know what is happening.

For some of us anything less than 90fps without reprojection produces unacceptable stuttering. It seems to be one of those "how you are wired" kind of things.

Also...

Some can handle 60Hz
Some find it smooth without reprojection at 55fps
Some hate reprojection

Hi,

 

I have tried to start the Speed and Angels campaign after I have installed the update as well but I can't get too far with it. I have Pimax 5k and I tried to run with PimaxXR but it can't load the first real mission. It stucks at "World preload 1/60". I tried the Fear the Bones campaign but I have the same problem. When I try an instant action with the F-14 it works fine, I can fly the mission. It seams it crashes when DCS tries to load something more complex stuff. If I try to load with SteamVR it loads but it's a slideshow.

Anyone has similar probles? Solution maybe?:)

Can I turn off Turbo mode manually in Your Toolkit? I checked this option but it crashes DCS 1 sec after loading (perhaps Motion rep. issue in current DCS and OpenXR). The problem is that now I cant turn it off because turbo option freezes DCS right away after loading. Thank You!

Follow the "Start in safe mode" bit, it is meant specifically for these situations where a setting prevents start up.

Having played around with it a little bit, this change has its pros and cons for me

I am no longer getting the framerates I used to get. They are lower now that I cannot use NIS and FSR (enabling them crashes my game upon startup)
At the same time my frames seem to be much more stable, rarely dropping below 45 (and rarely getting above 55, even in single player) (for reference, I had it tuned in to get a nice 60 FPS on the F-16 Caucasus cold and dark mission, my go to testing mission. Now I get around 50-55 there)
I did some tests, one of which was flying the AH-64D around on a busy multiplayer server on Syria. On this particular server, I'd often crash before getting to spawn in, now I was able to fly around without my frames dropping below 40.

Loading in of textures does seem a lot slower. It can take up to 20 seconds at times, where it used to take no more than 10 seconds usually.

I have no clue how native OpenXR support impacted all this, it might all be caused by something else entirely. I did not do proper experiments, I just played around a bit and this is what I thought.

For reference:
VR: HP Reverb G2
CPU: Ryzen 9 5900X
GPU: RTX 3080Ti
RAM: 32GB DDR4-3200
SSD: Samsung 970 Evo Plus (Has both windows and DCS)
