It took me 2 days to get it to work. Updated Nvidia drivers from 460 to 470, this part was critical, it's last thing I did that got it to work. added : "PROTON_USE_WINED3D=1 %command%", without the quotation marks in launch options, was also necessary.

Proton GE 7-55, necessary! I suspect GE might work as well, but I can't bothered to check, it works now :D
