Hola Don,  do you have sufficient disk space on any of your SSD's?  I know your position about not wanting to mod, (which is cool).   This would be extreme, but you could make a parallel copy of your virgin install.  Then use that 2nd version for testing things out?   Just a thought....

 

Yeah but not real fond of doing that at this time , thanks for the suggestion!

For the people who are interested, all it takes is dragging the files from the zip to the /bin folder. If you don’t like it delete those files and run DCS repair to restore the old OpenVR_api.dll.

Installation takes a few seconds, and removal process is almost as easy. This basically allows me to swap back and forth between Steam and OpenXR quickly when I did the comparison tests.

Then you’ll understand why people are raving about this in both MSFS and DCS communities. The ability to run your headset display at 100% resolution with decent framerate is a big deal especially if you have a high end setup and want to take full advantage of what your gear has to offer.

In that zip there are two files and two folders. The folder hierarchy gets unzipped into the DCS Bin folder as is, or does one need to copy the files out of those directories and paste into the bin folder?

One key point though - MSFS 2020 supports Open XR natively, DCS does not. 

I run my Aero at 100% resolution in Steam VR with default of High Varjo Base, and am very pleased with what I see in DCS which causes me to be hesitant.

Edit: Ok re-reading the OP seems I answered my own question, the files along with the folders get extracted to the Bin folder. I may have a look at this - we have family in with grandkids so it may be Saturday before I get a chance, they are leaving Sat morning.

I will be very surprised if this improves upon my already very good experience.

Now I am thoroughly confused when I go back to the download site from the link in the OP it downloads a bunch of files in the zip. I thought there were only 4? This why I do not like Mods. This is what I now have in that zip file. What happened to only the four files I needed? I am not putting all of this on my PC. Ain't happening.

I think you clicked on the source code link, you just need the file linked below it. I am not sure why it isn't clearer. I agree it is confusing!

Thank you! I guess he assumes we are all developers lol.

 

Edit: The downloaded files seem a little different and it states WMR? Aero does not use WMR.

Edited April 1, 2022 by dburne

I don't think the WMR naming matters it was simply originally written with WMR in mind.

FWIW this is what I did with a G1

Downloaded the zip file, extracted the three files I need (D3DCompiler_47.dll, opencomposite.ini, openvr_api.dll) and put them in a folder called openxr. Copied the original files from my DCS install\bin folder (D3DCompiler_47.dll, openvr_api.dll) and put them in a subfolder of my openxr folder called original.

Now I can just copy the files from my openxr folder to my DCS Install\bin folder to run openxr or copy the files from the subfolder original to run steamvr

Replace G2 with G1 as I don't own a G2!

[dburne]

I think I got the correct one now with the files I saw before, version says 0.6.1. It has four files but still says WMR.

Ok much thanks. I am reminded though how much I don't like Mods lol.

It also says ACC for Assetto Corsa Competizione! - it is just the evolution of the mod

I try and run as clean a version of DCS OB as I can, as so much stuff can break with a new release which mods running which clearly isn't ED's fault.

This one has seems to have such potential from a VR performance perspective that I have made an exception

[dburne]

I hopefully will try this out sometime tomorrow. We have grandkids in that will be leaving sometime tomorrow morning. First though I want to fly some with my new VR Optician Inserts in my Aero to see how everything looks. After that I may give this a try, emphasis on "may".

Ok the final verdict from me, been flying as much as I could whenever I’m home.  If you haven’t tried this with the Aero, you’re missing out…big time.  The ability to use 100% rendering resolution on the Varjo Aero while retaining decent fps just wasn’t possible before until now.  And the visuals are absolutely amazing at this resolution, note that I’m also using Higher mode on the Aero instead of default.  Everything just looks crisp, with next to nothing aliasing artifacts.  Not only that, things are bound to get better once foveated rendering works properly…and dynamic foveated (eye tracking) is also coming soon at least for the MSFS counter part.  Detailed FPS option from the toolkit will display CPU and GPU frametimes, and more for those who like to tinker—so fpsVR is not needed.  Sharpening is possible via NIS/FSR setting even at 100% scaling, it’s not as good as Reshade’s lumasharpen in terms of making things pop, but the overall visuals look more natural (a tad dimmer and less vibrant) rather than artificial.  The gamma is slightly different in OpenXR mode.  I normally use 2.0 with SteamVR, but with this I find that 2.2 is better.

 

Question for ya? Getting ready to try out Open XR with my DCS install with the Aero. I went ahead and grabbed the latest version of Open XR Toolkit as well.

However when I launch the toolkit this is all I get. Where are all those settings I see getting mentioned? I enabled "experimental settings" but that made no difference. What am I missing?

The options come up once in DCS when you press Ctrl-F2 (or whatever you change it to in the screen you just posted)

Ah ok much thanks!

[Supmua]

Just realized you’re using 1.0.5 already. I’m still using version 1.0.4 didn’t realize there’s already a new one.

[dburne]

No dice. DCS crashes with an Open XR not supported error message. Did a clean and thorough repair of DCS before dropping the files in.

This is the kind of stuff trying to get Mods to work as why I prefer not using Mods. Going to try to get it back to way it was , I would rather be flying today than troubleshooting.

Well I replaced the files with the ones I had copied out from my bin folder, still screwed up augh! Got 4 tiny images showing on my desktop and that ain't right. Why in the world did I try this... I really wanted to fly today rather than screw around.

Going to try deleting my entire bin folder and copying the one I saved outside of it back in.

Edit: Well that did not work, image on monitor still screwed up showing 4 screens. How the heck did a mod I simply copied into my bin folder manage to screw all this up. It sure did though. Going to now try a long repair of DCS again and see if it fixes it.

Don, just like previously you still have to force SteamVR mode with the exe command, but the wrapper will bypass that and switch to OpenXR instead.

Yeah I tried that, crash to desktop with Open XR error message. Guess I could try again as it is all apparently screwed up now anyway.

Try turning off OpenVR on the Varjo's app and just leave OpenXR on.

Same crash to desktop with Open XR error. Ok will try that.

Nope same crash to desktop with OpenXR unsupported app error message.

At this point I really just want to get my install back and working before I tried all this. Going to try a repair. Just deleting the files is not working for me nor is restoring my previously saved bin folder.

Edit: Did a clean and now going through the long repair process, hoping it gets me back to way I was.

Do I need to launch Steam VR also in addition to Varjo base when running the mod?

No need.  It doesn't care whether SteamVR is on or not, but you will still need to force DCS to run via SteamVR since the Opencomposite wrapper relies on intercepting that.  I typically have Steam on since it is my primary chat app with friends and I also use it for voice comm.

Still no go. This is error I get:

 

I thought it might be that I had only copied the three files over and not the folder, so I copied also the folder this time as yours showed and still getting the error above.
