P5R_d3d11.log

This line here means it's not picking up dxvk's dxgi.dll. (afaiu)

warn:  D3D11CoreCreateDevice: Adapter is not a DXVK adapter

If you've put it next to the exe same as d3d11.dll then it likely means the game directly looks at the one in the Windows system directory and there is nothing that can be done from dxvk's side.

The solution I used (and which did wonders) was to copy DXVK's dxgi.dll to dxgj.dll also and to change the imported DLL name accordingly in d3d11.dll (DXVK's one, not the system's :) - indeed, by looking at the logs it came to me as obvious that the DXVK's dxgi.dll is not even loaded, because DXVK's d3d11.dll tries to load system's one (dxgi's logs were empty). Sometimes you'll need to also change the import in the game's exes/dlls, sometimes not.

Sorry to reply after so long, but can you elaborate on what you did to fix it? I renamed dxgi.dll to dxgj.dll, and in d3d11.dll I used HxD to change dxgi to dxgj, but now instead of saying "doesn't meet minimum system requirements" the game just crashes instantly on launch. No log files are generated, and I'm really not sure what I'm doing wrong.
