for some reason the profile doesnt work in G3D for me (htc vive i dont know if that matters).
anyway, i did my own profile, based on firewatch official profile, and with this one i got the game working in G3D. so check cloud guys if you wanna try it.
my advice is to drop shadows to high or lower, if you set shadows to low you can even tweak FoV (with FoV vorpx settings) without any glitch.
do not use positional tracking, it causes glitches.
when using FoV vorpx tweak, the ui scale accordinly, it’s neat !
