Humm I know .23 just dropped when might this patch make it into the main line?

Unfortunately it probably won't. This issue happens because the openXR initialization that Metro Awakening does is off-specs, and WiVRn developers aren't very willing to get lax on checks to make it work: WiVRn/WiVRn#232

If you see on the bug report, I've even opened a bug report at PLAION (the publisher) https://playersupport.plaion.com/hc/en-us/requests/150094 but what happens on it is not open to the public. The best hope we have is that they fix it in Metro Awakening itself and a future patch allow WiVRn to run it without my pach.

Sigh so basically shit out of luck unless I want to go figure out envision and the many other complex moving parts or deal with crappy ALVR performance. Argh, thanks for clarifying.

any update on this ?
the people on linux adventures dont recommend using envision with wivrn so idk about using it

I don't see why they wouldn't recommend it. envision is not difficult to use and it solves a number of problems, including testing new patches, which is specially important for rapid evolving software as wivrn and xrizer.

It is the only way I use wivrn. And it is the best way to "solve" this since it's a patch, which means wivrn has to be compiled with this patch applied, and that's precisely what envision does -- automatically, just by depositing it in a directory.

You have the problem, you have the perfect solution for the problem, but you are hesitating because of some negative recommendation from someone. Do I count as "people on linux adventures"? Because I'm there too, I chat on the discord, I contribute to wivrn and the other software (mostly with bug reports), and I do highly recommend envision.

it was the only way i use wivrn too its just easier to personalize the build and etc.
i was using pure wivrn to avoid headache (but its seems this is not the case anymore)

and about the discord:
i think was some mod that responded to me. I ask something (idk what as) and they response with just envision its not recommended with wivrn, i asked the reason but got ignore lol.

and here is the part on the site that say:

Do not use Envision for WiVRn directly unless you absolutely need it to access experimental patches. See WiVRn as WiVRn has it’s own GUI much more suited to itself than Envision and may be installed via Flatpak, AUR, or Fedora repos.

but anyway the fix worked really well, thnks. the are only problem with cross eye effect. but i think its a problem with the game? seems it happens on windows too so idk

What is the cross eye effect? When I play the game the image appears correct, that I recall. I can try and check again to see if I have that effect if you describe it to me.

i was mistaken about the cross eye issue on Linux.
on Windows it happen (i might be wrong, but i tend to call cross eye effect any problem where one eye image looks different from each other).

on Linux, what i actually have is a vertical line between the eyes, which i can see when i move my head. i think its some kind of reprojection issue.

also, i broke my EFI partition on a sys update... lol, so i wont be able to give feedback today.

This patch is not working for newer versions of WiVRn. Please use this one instead: https://gist.github.com/Patola/227d2ae3185b9ffab95d807622871ee3
