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

Thanks for the prompt explanation, so if we leave this to default does it switch to 3160 per eye?

Not quite

If you leave the resolution override on default in the openxr tools desktop app, the resolution will be set at a recomended value based upon the amount of VRAM you have.  For my 12gb 3080ti it's a little over 3100 wide, for my 8gb 3070 it was about 2450 wide.  From memory the calculation is based on three back buffers with 4xMSAA applied to them shouldn't be more than 10% of available VRAM.

If you override the resolution on the desktop app and set it to 100% then it will be 3160 (or there abouts).  You can see the current set resolution on the second tab of the openxr tools desktop app.

I've been trying to keep up with this (or should I say, understand it), but if I were to lower my resolution to 75-80 in the desktop app, do I leave the toolkit (in-game) set to 100? Does the desktop give the maximum and the the toolkit is a percentage of that? Does that make sense?

[edmuss]

The desktop app will set a global resolution (either by the default VRAM calculation or manually overridden) and the ingame toolkit will then override this if set.  The two are not cumulative, it's either one or the other

Any rtx 3090 user that has tested differences in performance/visual quality between OXR FSR and NIS modes?

I'm curious of any head ups as to which one is better for that Gpu being nvidia.

Both are software solutions only and independent of hardware. There are differences in image because of how they handle the upscaling/sharpening but it's largely the same performance wise and personal preference with regards to the image.

Sorry for asking in here, I think its been asked several times. I've scanned this thread and many others for the answer but I'm not having any luck. I've found many threads with this problem but there is never a solution?

The OpenXR toolkit menu will not show in DCS with Quest 2?

I've tried everything suggested in multiple threads including-

scanned, cleaned and repaired DCS with skatezilla

Everything is up to date

DCS is listed in open composite

run full screen, alt Enter to make sure

and gosh, so much more, but no luck.

I was able to do wonderful things in MSFS2020 with OpenXR but I can't get it to work for DCS?

Question: have you downloaded and replaced the openvr_api.dll, from OpenComposite website, onto your DCS World bin directory?

are you following the steps shown in the attached image

there is no need for that if you follow the system-wide installation of the Opencomposite.  This is  only needed if you do a per-game installation

[Pickle72]

I did not download the .dll as I didn't think I needed to?

the screen shot looks right but I think the vr interface is set to oculus? I'll have to check when I get home. Could that be it???

 

Thanks

guys!

You may be right, but I would do that just to make sure.

[Pickle72]

That's all it was. I didn't switch to the steam vr rendering driver????

I cant thank you enough.

I gave up on VR in DCS. I just got my Track IR stuff back out. 

But thanks to Open XR its back! Running the Quest at 80Hz with a render res of 1.3 (4480x2256) and my old 1080 is able to achieve the coveted 40fps with a lot of bells and whistles turned up, including ultra clouds

So happy.

Thanks for the hand holding.

You are welcome. 

The whole idea for steamVR API use is to trick the system that SteamVR is used so Opencomposite can take over and use their own dll. So in reality no SteamVR is used.  

[Pickle72]

And that's why I was confused

But it makes perfect sense now.

Quick question, it's normal that when I increase in the tololkit the % decrease the resolution ?

Example FSR at 150% have less resolution of 100%

I think the answer is yes, if you are saying your native  resolution is 1000 and you use FSR  at 150% it reports a resolution of 500 (or whatever) then yes i see that too

[Tomcat388th]

I have yet to get the toolkit to come up with my quest2 .

Open xr tools for windows is showing the correct runtime  WMR runtime or whatever it called.

Skatezilla is showing the right options as the screenshot above a few post.

openxr toolkit has a ck mark for opencomposite_dcs. I have ctrl and the arrow keys mapped for changing options

And the opencomposite runtime switcher Status shows opencomposite 

I got it going I set the runtime back to Oculus

This is correct, upscaling values above 100% reduce the render resolution by the inverse. So 75% upscaling would be render resolution x 0.75, 150% upscaling would be render resolution ÷1.50.

And the opencomposite runtime switcher Status shows opencomposite or does it need to be steamvr. I thought I have tried both

Are you definitely running DCS with the force steamvr switch rather than the default oculus runtime?

Sorry if this has been touched on in the previous pages, but has anyone experimented with the Post Processing features of the OpenXR Toolkit?  Vigrance?  Highlights?  Shadows?  My settings so far, but not final:

Saturation 53%

Vibrancy 10

Highlights 95

Shadows 10

Hi,

 

With the latest update getting OpenXR, I guess we (G2 users, using WMR without SteamVR) don't need OpenComposite to bridge from OpenVR to OpenXR any longer... If we are using the OpenComposite app that lets you switch OpenComposite/SteamVR, how do we disable it (there is no uninstall, as it is not an "installed" app), to ensure it does not fiddle with the DLL any longer?

 

Thx!

I think that's mostly personal preference, it doesn't impact performance so you can set it to what you want.

You can just ignore open composite for the purposes of DCS now, if you still have it present on your system and you start up DCS in steamvr mode (openvr) then it will still translate it to openxr unless you set it otherwise in the open composite switcher.

Unless you have an Aero and still wish to use OXRTK.

Ah yes, that bit sucks

To be fair I've yet to get toolkit working reliably yet, as soon as I apply upscaling it falls over on mission load.  Only spent 20 minutes or so looking into it though and it was 1am so I'll probably get better results with a fresher head!

[dooom]

so can i delete opencomposite now?  i have a g2 and i think i'm interpreting its no longer needed.
