With my Aero I am finding with running the default HI setting for VB and set vysnc to on in VB, it does a good job locking my fps to 45 and a very smooth experience. Don't know how much Open XR is helping that but I will take it for sure. I tried enabling the default Fixed Foveated Rendering with the Open XR Toolkit and it introduced some ugly shimmering for me so I disabled it.

 

To be fair, if you've got a good stable image and no spikes then it's a good place to start turning settings up in DCS.

The toolkit performance uplift tools do so at a loss to image quality, many prefer to run without them as they somewhat sully the image quality provided by OXR.

What frametimes are you getting? I'm presuming that the VB vsync is working a little like reprojection. Enable the performance metrics from the OpenXR developer tools and look at the appGPU and postGPU readings.

Also what resolution is OpenXR running at? Unless you've set a custom resolution it will calculate a recommended based on your 24gb VRAM, the second tab in the developer tools will display the actual resolution that you're rendering at.

I really want to give this a try but I get stuck right at the beginning.  I can not clean or repair DCS World.  Is this because I bought the game on Steam?  When i try to repair using that Skatezilla program, it says the updater is corrupt.  So I downloaded an updater directly from ed and that one doesn't work either, it says it "can't exactly find the install folder" and when I confirm it is correct it doesn't do anything, then the Repair option never becomes available.

Am I supposed to go into steam and "Verify integrity of game files" instead of repair/clean?  If not, do I really have to re-install nearly 200 gigs just to test this mod?  Why can't it just have an install script like normal programs?

Does this forum have a search function that works on a per thread basis?  This thread is already 40+ pages deep and I'd like to search for "Can not clean"

I think the steam verify files will repair it and remove any modified files but I don't think it will remove any extra files.

Have you tried saving the ED update/clean/repair batch files (from the DCS FAQs page) to the DCS folder and running them?

edit: the batch files are here: -

Ok! Just spent a few hours trimming this with OpenXR. At first, it was <profanity>, way worse than my SteamVR setup with Reshade and OpenFSR. But after enableing Motion Projection in OpenXR everything went from super jerky to butter smooth. 

I also noticed turning up res to 150% and disablesing MSAA is an acceptable level of shimmering. 

I used Toolkit to increase Saturation to 60%, so it almost looks like the Reshade Mod for VR. However, I can not get the same sharpness as that Reshade VR mod.
Release OpenVR support with basic VR preset · fholger/reshade (github.com) 
 

Another issue I noticed in the Apache is that a get "tearing" on objects seen through the rotorblades, like tree tops, buildings and so on. Any way to get around that?

I guess I just need to check something first.  I can't get clean/repair to work.  My version of DCS World was purchased on Steam.  This explains how to get SteamVR out of the picture, so am I correct to assume the standalone version also used steamvr?  Is this OpenXR not actually compatible with the steam version of this game and all of you that have successfully gotten this to work are all on stand alone?   Has anyone that purchased this game on steam gotten this openxr to work?  I can't figure out how to re-calibrate my headset because it's not in this guide so I'll have to look up another tutorial just to figure that out.  But, how would I even launch the game?  I used to load WMR and in vr I would open steam and click on "Launch steamvr in steam VR Mode"  There is no Openxr mode listed, there is only play dcs world steam edition, launch steamvr and launch oculusvr.  So does this not even work with this version of DCS or do I have to create a desktop shortcut from the exe and edit the command line or something?

I gave up the cleaning part, and just deleted every shred of DCS files I had on my system, and then redownload everything from Steam again. Luckely I saved my profiles for F18, A10, Apache for each HOTAS. So it was a quick restore of the input profiles. 

[falken76]

Ok, so you have the steam version of this game?  How do you launch the game?  I don't have a "Launch in Openxr mode" option, do you just select open steam edition or select open steamvr version?  Did this even work to help improve your game?  I assume you have the steam version since you said you re-downloaded everything from steam.

I would do this at  minimum. Also maybe manually delete anything related to any other mods, then verify files via Steam.

As a last resort, you might want to take 'convert to DCS stand alone' route.

Once you've copied the files over to "bin", try launching via the DCS.exe there. I recall shortcut created by Steam adds something to the properties.

You can point a desktop shortcut to the DCS.exe in the bin folder, doesnt necessarily have to go through steam.

At this moment in time this is an issue within the implementation of MR and DCS; it's arguably worse than SVR at the moment but only really happens with helo rotors and props. The devs are aware of the problem.

No current fix or workarounds and it will get fixed as and when it is, that's assuming a fix is possible.

I launch DCS from the Windows MIxed reality "Club House". I think I can launch it from start menu as well, as long as you have ticked VR in DCS Settings.

Ah ok, thanks for the info. Well I think I can live with that for now. Really like the smoothness. 

I was just about to try and mix with NVidia settings to see if it was the cause. I have VR Pre-rendered Frames set to 4.

This worked.  I had to close the oculus programs through task manager.  But now when i run DCS from the shortcut, it loads into VR.  Task manager confirms that Steamvr is not loaded at all, and dcs shows it's also using opencomposit.  It must be working.

It was already there as an option mate, i just changed it to custom.
I think however it only shows when you change the menu, show expert settings to yes as below.

Had similar tearing, try NVIDIA control panel, 3d settings and setting Vsync to Fast. Worked for me.

Thanks for the info I will try and check some of that out tomorrow in my testing. The headset blacked out a couple of times on me today, something it has never done so not sure if related to the Mod, thinking perhaps it probably is. If it does it again tomorrow I may have to remove  the Mod and do some more testing to be sure it is not a headset issue suddenly.

Turn off Motion Reprojection or switch back to SteamVR. You can also use 3Dmigoto tool and disable rotor in Apache but it will look weird.

In my opinion, the OpenXR MR artifacts in MSFS are far worse than what I experience in DCS.

I gave up on playing MSFS in VR due to MR not working well enough.

In DCS, OpenXR MR works pretty well with the exception of rotor issues in helicopters and also excessive ghosting in jet fly by views.(F3)

Interesting, either way the devs are trying to get it as good as WMR4SVR is; perhaps if they can fix it for DCS they might be able to apply the same fix for MSFS

Just curious how many of us posting here are testing this in multiplayer servers? 

If you are, and are having similar performance (good) to single player, would you mind sharing which servers you are using? 

I had the same issue on our MP server. Fps went below 9 and did not recover. In SP it is all good. Tried the MP server before the squadrons were flying and it was still okay.

not gonna happen...     I'm sure a fix will be forthcoming.  Regardless, I'm enjoying this thoroughly with the Apache.  Getting better at my landings.

I get it pretty bad in jets.

[nairb121]

I've successfully installed OpenXR for DCS, and I'm liking the performance improvements, but I'm having an issue with my VR controllers now - the angle is no longer correct, they are rotated downward. (Reverb G2). How can I adjust the orientation of the VR controllers? 

[Nodak]

Programs menu, "OpenXR Toolkit Hand-to-Controller Configuration Tool", bet you'll find your answer there.  Comes standard with the tool kit.

This 100%

DCS is still DCS. Multiplayer complaints are for the lack of CPU utilisation which I highlighted a few times. Even Wags during an interview not too long ago has said that he expects much more performance uplift from multi threading implementations than from Vulcan. Man got a point. I can not name an other game which is CPU limited after I render over 7K combined resolution

So you installed Open XR, but nothing has changed, you still only have a couple of threads which are now supersaturated driving your eye candy. This is because you can actually take advantage of the connection between DCS and your headset. Now you gotta slog multiplayer shenanigans on top. Not an ideal metaphor, but if this is not making sense - Before with SteamVR you had a bottleneck which "helped" the multiplayer performance in the same way a closing of a few lanes of the motorway "helps" the merging traffic flow after the roadworks. Now that the roadworks is gone, for people joining the traffic flow downstream it has gotten more difficult

 

Understood, but for me it doesn't happen with SVR in multiplayer, with GFX and render scale set high.  

Multiplayer, when using OpenComposite, even with all in game options low (but DCS VR set at 100) and OXR Dev Tool render scale turned down to 20, eventually the stutters will begin, and will generally remain regardless of how complex or barren the scenery.

On my two systems it's behaving like a tap dripping into a bucket. Lowering the GFX settings slows down the drip, but ultimately it will full up, at which point the judders/jitters start. 

Other than this problem, it's fantastic
