I saw your post for this just tonight and sure enough all I had to do on my Fedora box / Bottles was enable the DXVK 3D. Pretty sure I tried this before but I guess a recent bugfix in Wine/Proton DX12 rendering engine fixed it!
It appears I need to use specifically Sys-Wine-10.4 in Bottles for the software to work without the notorious DX12 graphcial issue.
In order to install it though, I had to switch to an older version of Wine that wasn’t using the experimental WOW64 implementation or smth. I think they are talking about it here. The best solution would be to compile the latest version of wine yourself it seems. WOW64 mode does not seem to work on anything - WineHQ Forums
The software is still a bit unstable within Linux. Not sure if the stability issues are also present on Windows.
