OpenXR Toolkit, Meta Quest 3, and DCS

[Hootman9104]

Hopefully posting in the right place. Hoping someone smarter than me reads this and can maybe look into this and see if my assumptions are correct.

Recently moved to a Quest 3 from Reverb G2. With the Reverb, I was using Opencomposite with Open XR Tools for WMR, and OpenXR Toolkit with great results.

Of course with the Quest 3, Open XR Tools for WMR is out. However searching around it seems that the OpenXR Toolkit is still working as long as we're using OpenXR runtime (think I'm using that term correctly).

On the OpenXR Tookit Project Github, the dev (who to my understanding is/was actually an employee that works on OpenXR and was doing the Toolkit on his own to test and provide new tools he hoped to eventually get in OpenXR officially), on the page he has in red bold about discontinuing due to Meta/Khronos implementing their own OVRPlugin, and whatever problems that causes. This was sometime in 2024.

So I searched around, and noticed that on Jan 23, 2025, Meta posted extensively concerning OpenXR (link below), and this is where my question lies, as much of this tech speak is over my head.

Is the gist of the Jan 23, 2025 update on this site indicative that Meta has changed course and is openly supporting OpenXR as we know it, and NOT implementing some sort of OVRPlugin that the dev of OpenXR was referring to??

Based on what little I understand of all of this, that would be what the OpenXR Toolkit dev was referring to, and if my tiny peabrain is reading things right, then Meta is NO LONGER heading down the path of restricting things as the OpenXR Tookit site refers to.

Am I correct in this assumption?

NOTE: There appears to be a SEPARATE page on the Meta site for Unity, that addresses the "XR Plugin Management for Meta Quest", maybe this is what the OVRPlugin is reference to?

Also, I'm still early in adjusting/setting things using the Meta, and wondering if any out there have had good results using OpenXR Toolkit ingame to help with DCS.

Thanks!

I still use OpenXR Toolkit, pity it's not supported anymore by its creator (not critisizing mbucchia here, he's done a lot for VR in DCS). Quad Views Foveated is an alternative tool made by the same author, but in my case I get worse performance so I don't use it.

Turbo Mode eliminates ground stuttering almost completely, and the overlay provides in-game CPU and GPU frametimes. Those two settings I cannot live without.

Post proccesing to simulate sunglasses it also comes in handy, as half the modules lack the feature.

Just getting ready to try DCS with this new headset now. Hoping the XR Toolkit works, didn't seem to pull up in IL-2 for some reason. Still have it installed from the Reverb 2 I had.

Also appears that Opencomposite still works, which is great, as I'm not sure which is better/worse, the Oculus/Meta XR runtime, SteamVR, or the Steam XR. Since I had best results with Opencomposite and OpenXR Toolkit, hopefully everything still works. And yeah man, that Turbo Mode is the best

When did you try? I tested IL-2 last week with OpenComposite (I was trying to bypass the nefarious SteamVR) and OpenXR Toolkit kicked in on its own when the game opened. It was a pleasant surprise.

Absolutetly true, I cannot stress enough how important Turbo mode is.
Terrain stuttering is completely gone since Turbo mode exists.
Even my older rig having the 1070 GTX and a Intel i7-6700K processor and my CV1 had no terrain stutters with Turbo mode at 45 fps.
And yes, this one was a very slow rig ...

With IL-2 Opencomposite all I got was the steam "next up" screen just sitting there. I'll give it another try. Still learning the funky ways to connect with the Quest 3.

Just found that:

OpenXR toolkit is the one and only solution available at the moment to remove terrain stutter if it is there without the toolkit.
What do we do with such information on the Internet, I mean, how can we keep DCS running fluid if such postings exist and the toolkit someday becomes removed?
I took it from here: https://www.8492sqdn.net/guides/dcs/performance/
On the other hand one can see this as a specific "squadron procedure", because none of the members has any problems with terrain stutter ...

OXRTK still has some relevance but it's not a magic bullet. Turbo mode can help but it can also make things worse in some cases. It very much depends on your setup. If it works for you now that's great but it's not something that should be automatically enabled by everyone in VR.
