Got it... seems I was thinking backward. The the left edge of the right panel was actually encroaching over to the left fov. I edited both to match.

You’re far better off with a full custom mask

im going to make a guide for it as you’re not the first to ask this question 

1) disable mask inside ini

2) enable the log above

3) launch DCS. (I do a quick start mission to make sure everything still actually works) then quit

4) Access the VR log inside the root directory of DCS (NOT BIN FOLDER)

5) copy and paste the values about half way down the document you will find them somewhere

The original post said "For the record I was getting a GPU frame time of around 9ms and CPU of around 13ms with SteamVR and I am sitting on 19ish with OpenXR. OpenXR is miles better!"

Is this correct? I thought a higher ms frame time meant lower fps? How could getting 19ms with OpenXR be better than 13 with SteamVR?

Apologies if i'm reading this wrong.

Also, i'm only getting around 70 fps and even with motion smoothing on or auto, the view (& fps) still fluctuates and is not a smooth experience

Because in order to achieve 45FPS you’re looking for roughly 19ish millisecond frame time 

You’re softlocked to 90/45/30 etc. If you have 3090/6900xt whatever and sitting at lower settings unable to get 90FPS but are getting close; this means that you're sitting in your Ferrari doing 60km/h. Which is fine, but I doubt you bought your high end setup to be only using a part of it

Even if you *think* you are getting 70fps what you’re likely are getting 45 then 90 then 45 again. Why don’t you turn settings up and enjoy a stable 45FPS instead of the performance 

Its not possible to get 70FPS

If you enjoy lower settings (more power to you) use OpenXR Toolkit to lock you at 45 so you don't go barreling over 90FPS/10ms and then back again to 45FPS/20ms

I have 6900XT (Gold silicon sample) and an older 3900X CPU and I can have things cranked including the performance sapping MSAA

P.S. God Damn! Motion smoothening is refusing to die no matter how hard I try. As I said, I am not here to kink shame - But why complain about it to me when I say to avoid it like a Hokum trying to get away from a pair of javelins

I'm not in front of my PC. But I think you are looking at the wrong line inside the log file. Alternatively delete it and get a new one. I also want to check you're looking at the correct log file (It's not the DCS log)

When I am at my computer I'll regenerate mine and post screenshots

Sorry does that mean you solved your issue. Or as in understood my message?

Thank you for this.

I had great results but i still can't live without my motion reprojection.

And reprojection works with openxr in less demanding scenarios - single player missions.
When i tried it on a populated MP server it got a stuttery mess. Reconnect without reprojection was fine. (Tried that multiple times to confirm.)

So i'll surely be back when motion reprojection support get's improved one day.

 

Same for me. Sim is unplayable until reprojection is fixed, so for me, can't use sadly

Sorry. Resolved... I added an edit to my other post above.

Hello,

Does it work with the steam version of DCS ?

[edmuss]

I believe it does, you can always convert steam licenses to stand alone though

[Hotdognz]

I have followed the instructions to the letter and using 0.6 I keep getting this error, anyone have any ideas.

Yes, it does seems so. I have the Steam DCS variant installed on my system and have managed to run DCS via WMR and without it calling SteamVR. So it does seem to work. I just had to get used to starting DCS from within WMR (never done so before).

Have you tried copying all of the files back into the bin folder?

The updated D3Dcompiler_47.dll also needs to go into the bin folder in addition to the opencomposite.ini and openvr_api.dll

Yep, I did a reboot and that seems too have sorted it out

[A.F.]

The question is: is my GPU (2080 S) even good enough to notice an improvement with OpenXR?

i guess so, you'll just have to test it

[edmuss]

Any gpu will benefit from it within reason.

Don't look at it as a performance increase (although invariably there is some) but more of a quality increase, for the same image quality you can reduce settings and thusly improve performance; alternatively keep the performance as is and improve image quality.

[kraszus]

Is this for WMR headesets only? Does it work with Quest 2?

[nikoel]

Added instructions and screenshot of how to get your own mask. Not required but recommended!

(Also might solve your IHADS issue in the Apache and make your aim a little less Storm-trooper like?)

I believe that DCS uses the quest natively with the oculus runtime which I think is openxr already?  If you run the quest via steamvr then yes it should make a difference.

Try it, if it works and makes a difference then you know it works

On a fresh reboot, opencomposite works fine. But if I close DCS and try to run it again, I get this same error.

Kind of annoying to have to reboot my machine if I want to tweak settings.

I cleaned and repaired my DCS install, no effect. Deleted metashaders2 and fxo, also no effect. Here is my openovr_log from a failed run.

 

EDIT: Restarting the windows perception service seems to also fix the issue, as a better workaround than rebooting my entire machine.

i had the same issue.

managed to solve by restarting wmr portal and killed some process named acc.... etc....

but after that after à 3rd or 4th dcs boot. issue went back and first method was unsuccesful. i had to rebbot my computer. i guess à computer reboot is the best method.
