Apparently this issue can be avoided by making the game think that there's an nVidia GPU with something similar to https://github.com/doitsujin/dxvk/issues/832#issuecomment-449826841.
@kisak-valve Thank You :) I had
dxgi.customDeviceId = 1C81
dxgi.customVendorId = 10DE
these added
dxgi.customDeviceId = 10de
dxgi.customVendorId = 1c06
Game Worked, narrowed down to
dxgi.customVendorId = 1c06 specifically enables it to work for me.
I can't create a party with my friend, it simply says "No friends are in the game" (which is not true). When trying to open the friend list in Origin overlay it sets itself to offline and it prints an error: "We can't connect you to your friends list or chat right now. Hang tight, we'll get you chatting with friends as soon as possible".
I assume that it's a problem with Origin in general, what would be the best place to report it to? Or if it's a known issue where could I track it?
Strangely, the matchmaking multiplayer works just fine. You'd think that if there was a problem with Origin network then the multiplayer wouldn't work altogether.
Game Is Seeking a Windows Driver Version It's Unable to Verify/Satisfy
Reproduction
Launch Star Wars BattleFront with Proton 5.13-6 on an AMD Gpu.
I acquired and tested this game today, the bug is still present.
As described by @jph168, I placed a dxvk.conf text file in the same directory as the SWTFU executable, with the contents:
dxgi.customVendorId=1c06
Then the game starts fine.
