2.48.1

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
