OpenXR Toolkit Tuning Guide (updated 21/02/23)

I'd try binding a different key combination and see if it's somehow linked?

With compostie version 0.6.3 the whole installation and use process for this appears to have changed. (https://gitlab.com/Jabbah/open-composite-acc/-/releases)

Does anyone have a link to an updated "how to" guide since the move to 0.6.3, which steps me though each download and install?

I have looked at a few YT videos that are as recent as March 2022, and they all seem to be referring to the older 0.6.2 layout, the links for which are no longer usable...

@philstyle I followed the install guide here: https://gitlab.com/znixian/OpenOVR/-/tree/openxr#downloading-and-installation. Effectively these are the steps I used today to install it (I was using 0.6.3, which I can explain if you want) However, :

1. I am using OvGME, so I created a mod folder "OpenComposite/bin to place it in the DCS "BIN" folder to include the 64-bit (required below) openvr_api.dll (https://znix.xyz/OpenComposite/download.php?arch=x64&branch=openxr).

"Find your game's openvr_api.dll file (this is in the DCS/bin folder), and replace it (though I highly recommend keeping a copy of the old file if you want to switch back) with one of the DLLs available above. Be sure to get the matching platform - if the game is a 32-bit game you need the 32-bit DLL, even though you're probably running a 64-bit computer. Simple solution: if one doesn't work, try the other.

2. Download the OpenComposite Launcher.

3.Unzip it to a folder of your choosing (Used the OvGME folder I created, and run OpenComposite.exe.

4. Click 'Switch to OpenComposite', and wait while the DLLs are downloaded. Games will now run via OpenComposite rather than SteamVR."\

5. Download OPENXR toolkit latest is 1.1.4 https://github.com/mbucchia/OpenXR-Toolkit/releases/tag/1.1.4

6. Install OPEN XR toolkit

7. Run OPEN XR toolkit, I changed the menu keys to CTL+ALT with the arrow keys. 

8. I have a PIMAX, so needed the PIMAXXR latest is 0.2.0 https://github.com/mbucchia/Pimax-OpenXR/releases (not sure if you have a PIMAX or not)

9. Launch DCS and press the OPEN XR menu "down" key to open the menu and tune as required.

*Note, the latest OpenComposite, OPENXR tool kit 1.1.4 and PIMAXXR 0.2.0 work together. I found using different versions eg 1.1.0 and 0.2.0 didn't work only 1.1.0 & 0.1.2.

This video has a good explanation of the Open XR tool kit (relevant to DCS too): https://youtu.be/pihlOD6yhsM

Good luck

Interesting...  I used to set SVR to 100% (and the numbers read 2160ish below the per-app slider) and it looked fine.

The lense distortion correction point seems like marketing speak to me...  But I'm not sure.

What I do know is the higher you go with the resolution the harder spotting becomes in VR...  to a point...  You can go low enough that it just looks too pixelated so you can't spot (aircraft anyhow) and you can go high enough that the "dot" that is a plane gets removed or faded by the SS routines.

With both my current G2 and my old Vive I found the best setup for spotting enemy air is real close to 1:1 native pixel res...  or just a bit over...  like +10-15% pixels.

 

Yeah the mismatch in resolution is an odd one especially as I believe the G1 used 2160 as per the panels; but the 3176 @100% was confirmed by HP tech for the G2.

Seems to work until I press the key combination to get into the settings menu. Only during a flight though. Functions fine in the DCS home screen.

Mine started doing this a couple weeks ago. Haven't found a cause but, most of the time if I restart WMR and DCS it doesn't occur on the next launch. But will sneak back in later. Like it's every other time.

Mine only started since I changed from an ovgme install to the new automatic system wide installation.

The video helped me a lot for the settings of my G2 thank you for all these details.
Thanks

[Roller25]

Seems my issue might be related to the latest OpenXR update. Unticking the use latest preview box fixes my problem.

The DCS logo no longer appears in the Open composite window, so I uninstalled Open composite and reinstalled it and when I started DCS it (dcs logo) was still not there!
Does this mean Opencomposite isn't working?

Have you tried running it in 2D to check that there isn't a problem with DCS itself?

[edmuss]

Also, if DCS is running in the headset and steamvr isn't running then yes, open composite is working

[PLUTON]

Now the DCS logos are back in the Open composite window, apparently all is well on that side.
thanks for support

One more question and I’m gonna get this rolling tomorrow, so in the guide it says 3 things needed but didn’t mention OpenXR developer tool kit… so I’m gonna have to download that as well ? I’m sorry I’m so far behind. 
 

thanks

There is no such thing as OpenXR Developer Toolkit

There is OpenXR Tools (former OpenXR Developer Tools)

There Is OpenXR Toolkit

They are mentioned in the guide and it's still 100% correct as of writing 

[Burt]

Okay nikoel clear enough thank you.

Has anyone seen this error?  I know there's a post about it on the GitHub but no response on there as to the cause.  I had OpenXR installed and working, then closed out for DCS for the evening and went back in today and the error started up during DCS splash screen.  When I click ok to acknowledge the error, it closes out DCS.  There has never been a C:\projects\openovr\openovr\Reimpl folder on my computer.

Hit stubbed file at C:\projects\openovr\OpenOVR\Reimpl\BaseRenderModels.cpp:342 func GetRenderModelName

So the oxrtk res slider is like the SVRCR slider?

The desktop openxr tools resolution override slider is about analogous to the steamvr supersampling slider. I'd recommend leaving it at default and using the resolution override on the system tab of the in-game menu.

Gotcha ! Thanks again

Hi, could someone more intelligent than me please help me with a small problem?

 

I have installed evryything without a hitch and it is all working wonderfully - thanks to all who developed this.  Incredible work.

The only issue I have is that I constantly get a thin bright white breakthrough of image on the bottom edge of the display.  It seems to appear when on top of a cloud layer etc and so I suspect it is something to do with the VR mask not being big enough?  I've looked everywhere to try and find out how to fix this and seen suggestions about "making own mask", but no joy in discovering how!

 

I have created an opencomposite.ini file in the game bin directory and applied the MeshFix line, but no difference.

 

Using a Reverb G2.  Can someone steer me how to fix this please?

 

Many thanks in advance.

Same here Jon , I’ll be tackling that this morning. At first I may have accidentally slid the inner ring to 56% and changed it to 60% from my research on a YouTube video. I thought about it in my sleep last night so I’m gonna try to put it back on 56 % to see if it makes a difference. We are in the same boat I started this OXR on Saturday and I had a lot help but I’m still trying to tweak the , I guess they call it the jelly effect in F2 view or flybys I. A dogfight. I’m just trying to get it like SVR was then tweak from there.

You can't get rid of the jelly effect through the tool. It's something that Microsoft need to address as I understood it. They only way to be rid of it is to turn off motion reprojection.

[Burt]

Oh wow ! Okay then I guess I’m as close as I’m gonna get then. I guess today I’ll test without MR, I really like though but I guess I need to try without. 
 

Thanks !

[edmuss]

You should find that clarity without reprojection may be better as well, it makes it all fuzzy for me when it's on.

Try it with WMR running at 60Hz. If you're one of the lucky few who don't get or can't see the strobe/flicker at 60, you will love the performance and there's no need for MR.

Also, without the need for MR, you can utilize the "anti shake" slider from the toolkit menu. Really steadies VR pointer-head movements.

[Burt]

Right on will try 60hz here in a few. So disable MR in both oxrdt and the ingame toolkit and just run 60hz ? Ill give it a shot. 
Thx SR !
