HP Reverb G2 and iL2 with Openxr tool kit and some Start up changes I made and wow

[OG__Iceman_VR]

 

[Chilli_40]

I've recently changed over from a Quest 2 to the reverb G2, and I'm having a heck of a time trying to figure out descent settings, "go figure"! This video refers to Open XR ToolKit, does this mean you're running in Open XR, instead of using Steam VR? I think I have all the things downloaded for Open XR, but I'm somewhat afraid to try it without a clear set of installation instructions. Reading through all the treads posted on the Open XR topic becomes very confusing after a while.

full_width and full_height is the resolution the game will render on your screen (the desktop mirror) if you set fullscreen enabled. You do not have fullscreen enabled, therefore it is doing absolutely nothing. And if you had fullscreen enabled the only thing it would be doing would be reducing your framerate because you'd be rendering the desktop mirror at higher than 4K resolution for no benefit whatsoever.

 

Right after that, the processor setting in msconfig is for limiting the amount of cores Windows uses. Setting it to max changes absolutely nothing, it's the same as leaving the option unchecked. It is not "defaulted to 1 core", at no point was there ever a windows update that limits the use of your CPU to one core.

I would like to try Openxr too, due to the low frame rate achieved with SteamVR. I tried to use Opencomposite with WMRforSteam, but clicking on "configure" opens an empty window, while I think the IL-2 logo should appear.

I too would need detailed step-by-step instructions ...

Could anyone kindly help us?

 

Thank you all

These should get you rolling:

Good video. I just bought the HP G2 and will be using this as a guide. 

 

[McFly60]

It's surely some my mistake (unfortunately I'm not an I.T. expert) but I'm still not able to run IL-2 by OpenComposite.

I followed (I think...) the instruction found on the suggested pages, but the result is shown below: the same blank window.

 

 

After this, if I run IL-2 this is the message:

 

 

Clicking "OK", IL-2 starts the same but in 2D (no VR)

 

What's wrong?

 

Thanks!

“Download the DLLs: 32-bit 64-bit

These come from AppVeyor - whenever I push some new code, it will be compiled and uploaded to those links automatically.

Find your game's openvr_api.dll file, 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.”

 

 

from. https://gitlab.com/znixian/OpenOVR/-/blob/openxr/README.md

 

I downloaded both 32 bit and 64 bit .dlls, renamed the originals so they werent overwritten and replaced them with the downloaded ones.  

 

Edited June 23, 2022 by SIA_Sp00k

[McFly60]

I replaced openvr_api.dll with the 64-bit one downloaded, both in the .../bin/game and in the .../bin/viewer. 

Then I tried to run IL-2, first directly (no other programs activated), second running WMRforSteam before. In the second case VRSteam started automatically, but I closed it before running IL-2.

In both cases the message below was shown:

 

Below the files replaced in both folders:

 

This is what I downloaded from OpenComposite

 

 

I'm probably making some stupid mistakes, but I can't figure out which one...

 

 

[DBCOOPER011]

I was getting those errors for the longest time, and it turned out that the openvr runtime wasnt set as active in the openxr for windows mixed reality app. Once that was clicked, I had no issues.

When I am talking about the multi core. that in in the Nvidia settings. Multi GPU has never worked in this game. CPU has to do with you PC and GPU using extra cores if the dirx app allows it. I still see the over all image in the game squashed and I can't spot as far away when I turn it back to the desk top default vs 3092x3164. What do you see.

 

PS I have more videos about how to setup OPENXR toolkit so it works. Prior to this one.

make sure you are using a 64 bit os. 2nd Check to see if the game is set to start in vr and the full screen is unchecked. Last download the dll and replace the dll in il2.

Take it easy, tough guy. "Confused" is not an insult but it is what I see in what you posted above.

Why are you guys replacing .dll's and not using the current all in one switcher app that updates automatically?  That old system of manual files swap is no longer supported any way.  Your confusing people, it's far simpler than this, and your losing the ability to instantly switch back to steamVR without doing any file swapping.  My game is all stock, no files added or swapped, and it runs just fine.  I can revert to steam with the opencomposite switcher app in a second, and it always auto updates to the current release. 

 

Why would you want to go that route?  What's the advantage?  Does sound like confusion to me.  Been an open composite user since day one.

Hi [CPT]Crunch, could you help me? In my previous posts there is the story of my issues with Openxr, and what I did until now. 

I followed various instructions and suggestions I find in this forum, but with bad results, I think due to something I did wrong.

The currently issue is the error message when I run IL-2:

...openvr_API.all was not found.

If you took 30 seconds to watch any of my YouTube so you would know I already mentioned both ways and I tried them both and they both work.

Have you tried using the swap file method previously for any other mod like FSR/NIS?  You probably have a modded openvr file.  Try this, it's the original stock file, so you don't have to do a complete reinstall.

No, so I have tested this multiple different settings. In the height which setting which is in the top portion which traditionally is controlled by the flat screen will go to the default flat screen Heights with setting. Trying to solve an issue I was getting when bringing up the maps with in the game I decided to just change those to match what the HP Reverb was using under the or height with settings. After doing so I happen to notice that the clarity and the ability for me to spot airplanes Beyond even 5,000 m of course they always disappear at 5K and then reappear once you cross that barrier and the ability to ID planes much better than previously. Now this could be a combination of the openxr toolkit along with the latest NVIDIA drivers that cause this to happen but every time I lower those settings down I notice a degradation in the overall visuals and a greater amount of jagged shapes along the edges of Lines within the game as if the anteling wasn't working at all but when I go back to the same settings as the HP Reverb then the issue seems to go away and the clarity spikes way up. Again I was asking the community to tested and hoping to see that anyone else notice the same thing or they didn't notice anything at all so I could start working backwards and figure out what was causing this

In fact, the problem changed after implementing what was suggested. I no longer have errors concerning the openvr_api.dll file.

openvr_api.zip 142.02 kB · 0 downloads

 

I replaced the file in the folders ... / bin / game and ... / bin / viewer with the one you attached, but nothing has changed.

 

Currently I can switch from OpenXR to SteamVR from the OpenComposite window. Selecting SteamVR I can run IL-2 without any problems.
Switching to OpenXR, when I run IL-2 the game returns the following error message:

 

 

Clicking "OK" the game starts in 2D way.

 

Many thanks to all the members who tried (and will try, I hope) to help me

 

[Comrade_Weng]

Can't see it previously suggested but are you starting il2 through steam or as a stand-alone with steam closed?

[McFly60]

After selecting OpenXR in OpenComposite I have tried to start IL-2 in two different ways: directly without any other open app, or running first OpenXR (I can see the house in the HP Rev G2) and then running IL-2.

In both ways the error message i attached above appears.

SteamVR is always closed when I try to play using OpenXR.

[Drano]

You can't simply swap out the dll and try to start the game right away. You have to swap out the dll with the runtime stopped before it takes. How I did it was, swap out the dll and restart the PC then everything worked. Give that a shot.

[McFly60]

Done, but unfortunatly with no result...

I also noted if I swap dll to OpenXR, try to run IL-2 (error message), close IL-2, swap to SteamVR, run IL-2, the game starts normally. It doesn't need to restart PC.

..if I start PC with OpenXR selected, swap  to SteamVR and then run IL-2, the game starts normally the same without restarting PC.

Did you check your Windows Mix Reliaty and turn off startup in steam? I noticed it fixed my startup when I was trying to get it to work the 1st time. And when you start Il2 just start the game on your pc not from steam. You can locate the il2.exe in your il2 folder if you have the steam version. Also make sure Il2 startup is set to start up in VR and the full screen is unchecked. That will cause you to crash.

I'm not sure. This could be the problem, I think. Could you specify in detail what have I to check? What app, what page and what option? Please attach an image, if you can. 

 

What I note is when I start WMRforSteam,  automatically the PC connects itself to my Steam account, and immediatly starts SteamVR. I'm not able to eliminate this action.
More: I have just noted that OpenComposite, previously selected for OpenXR, after started WMRforSteam like above, swap to SteamVR by itself.

 

You can locate the il2.exe in your il2 folder if you have the steam version

I don't have Steam version of the game. I have a shortcut of IL-2 on the desktop.

Done

Hi folks, me too had the same issue a year ago. I see to remember I disabled Steam VR self logging-in and I mantained WMR only. As I said to McFly60 I don't remember how I done that.... I think SteamVR causes a lot of problems. I hope for a sobstitute in the future....?

Yeah, I agree, the problem is SteamVR in my opinion too.
I have just uninstall Steam, SteamVR and WMRforSteam. Then I have installed Windows Mixed Portal and OpenXR Tool from Windows site. I swaped .dlls in IL-2 by Opencomposite. I can see the cliff house with my HP G2, but the usual error message has shown when I try to start IL-2.
I'am afraid a lot of informatic fun expects me before I can fly again...

You don't need to replace any .dll files if you use the OpenComposite Launcher - the bin/viewer directory only contains files related to the model viewer (Viewer.exe in the same directory) so anything you do there has no bearing on the game's executable which is in bin/game.

Things to check - do each one separately and then attempt to start the game after each one:
 

1. Make sure that indeed in F:\OpenComposite\Runtime\bin\ there is a vrclient_x64.dll - if there isn't, open up OpenComposite Launcher and press "Switch to SteamVR" and then switch back to OpenComposite so it downloads the latest version. If the file does exist you can redownload it by deleting it and doing the above toggling so it redownloads it. That should rule out a corrupted download.
   Note: these vrclient.dll and vrclient_x64.dll files are the same as the openvr_api.dll files you can manually download, just renamed to the above names.
    
2. In bin\game you should not have a d3d11.dll, D3DCompiler_47.dll and/or a dxgi.dll files . If you do just rename them by adding an underscore (_) prefix to their name or move them to a different folder or delete them (if you don't want to keep them). If they do exist they are remnants of some older mod you tried to install.
    
3. Make sure you have the latest visual c++ runtime from here:
   https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170 - get both x86 and x64 versions and install them.
    
4. Finally if the above do not work or do not apply, in your game's data folder add an opencomposite.ini file with the line:

   initUsingVulkan=false

 

The function it mentions (vkGetPhysicalDeviceProperties2) is part of OpenXR's Vulkan support (which is what #3 tells it to ignore and not try to use, but normally you should not be doing that so only use it if the rest of the steps fail). Also such entry point missing errors can be triggered by missing runtime files further up the chain and the last consumer (il-2.exe in this case) erroneously reports it as a missing procedure in the first intermediate library that triggers the error, that's what step #2 should fix.

Sometimes the opencomposite switcher app farts on update or doing something else, if it ever gives error messages, shut everything down, delete the entire Runtime folder and that re-start the app, it'll build you a whole new one based on the newest update.  That'll solve many issues.

Random black screen flickers on the G2 were initially caused by low frequency audio volume levels, HP had released a firmware update for the version 1 G2.

 

Full blackout (the screen doesn't re-activate) - if the cable is in good condition and seated properly on both ends - might be related to power issues, make sure that the Windows power plan you are using when playing doesn't have USB selective suspend enabled:

 

If that doesn't help then open up device manager and find the headset node and simply click on it to highlight it:

 

Then in the menubar click on View->Devices by connection and it'll display something like this:

Right click on each parent node up to the PCI-to-PCI Bridge, select properties and in the Power Management tab uncheck the "Allow the computer to turn off this device" option.

I have just followed the four steps you suggested, but the game does not run and shows the usual error message. In details:

 

1. there is

 

2. I have only the highlighted file below, starting with dx... no one d3d... I also renamed this file adding an underscore prefix, but in this case the message said the game can't find this file, and didn't run. I renamed like the original one. 

 

 

3. Downloaded and installed

 

 

4. Done

 

 

 

Is it correct that in .../bin/game there is the file named openvr_api.dll, not the same as in Opencomposite? The app is switched to Opencomposite. 

 

I attached the pictures so you could easily check if I did some mistake...

 

Thank you so much, I really appreciate the time you spent on my problem.

Yes the openvr_api.dll you have there is correct (should be the one that Cpt_Crunch sent you as the filesize appears to be the size of the original .dll).

 

However on step 4, the opencomposite.ini has to be placed in the data directory, not the bin/game directory - when using the system-wide installation via the OpenComposite Launcher it will search for opencomposite.ini in your case in F:\IL-2 Sturmovik Great Battles\data

 

If that does not work, then we have to find what's missing from your system - to do that download Dependencies (https://github.com/lucasg/Dependencies/releases) which is a tool that shows to you which other libraries a .dll or .exe depends on - unzip it in a directory and run  DependenciesGui.exe - then ctlr+o and open F:\OpenComposite\Runtime\bin\vrclient_x64.dll - it should then show a list of what files are used and if one is missing it should be tagged.

 

For example this is how it shows up on my end:

Yes the openvr_api.dll you have there is correct (should be the one that Cpt_Crunch sent you as the filesize appears to be the size of the original .dll).

 

However on step 4, the opencomposite.ini has to be placed in the data directory, not the bin/game directory - when using the system-wide installation via the OpenComposite Launcher it will search for opencomposite.ini in your case in F:\IL-2 Sturmovik Great Battles\data

 

If that does not work, then we have to find what's missing from your system - to do that download Dependencies (https://github.com/lucasg/Dependencies/releases) which is a tool that shows to you which other libraries a .dll or .exe depends on - unzip it in a directory and run  DependenciesGui.exe - then ctlr+o and open F:\OpenComposite\Runtime\bin\vrclient_x64.dll - it should then show a list of what files are used and if one is missing it should be tagged.

 

For example this is how it shows up on my end:

  Reveal hidden contents

 

On step 4: I misunderstood your sentence, my mistake. The file should now be in the correct location.
But the game still doesn't work, showing the usual error message

 

 

after running Dependencies, here below the report
