I did a lot of tinkering with this to get it to work and then ended up not needing anything other than the launch option to get it to run everyting fine with proton 8.0-5.

1. inital run with launch options '%command% -ignore-windows-system-certs' complained that I didn't have directX 12 compatability, which is not true for my system.
2. first I tried to force it to use directX12 through launch commands worked mostly but threw errors and crashed in menu.
3. second tried to force directX12 through vulkan with launch commands 'VKD3D_FEATURE_LEVEL=12_2 VKD3D_SHADER_MODEL=6_6 %command% -ignore-windows-system-certs' this worked but now wine threw an error from its c++ library "!status && "vkCreateGraphicsPipelines"". Well ignoring it and clicking the game window worked and the game got all the way to loading into a world except never left the loading screen even after by the audio I could tell it should be in game.
4. I finally had the thought that I should check if I needed to update my video drivers just in case. so I ran an update on my linux system and many things needed an update but the important ones here are my amdgpu drivers and wine 9.2-1
5. After that update I tried runing it again with just the original launch options '%command% -ignore-windows-system-certs' and it worked perfectly, I even now noticed that I had a backround environment in the character selection screen that I didn't even know was missing in my other run with the forced directX12 through vulkan. Game runs quite well now too. 90% sure the wine update fixed it.

* TLDR - if the game says you don't have directX12 make sure you're wine is at least 9.2-1 that and the launch options should fix everything.
