I managed to get the game to launch past the DX9/DX11 (DX11 greyed out) selector launcher (protontricks with all the directx9, dotnet40, dontnet45, gfw, xaudio, xact installers installed and a few manual installers for newer gfwl versions), however, all I can visibly see is a black screen and I have to alt-tab out to regain control. The game does not load to the menu or any cinematics. This game is not known to work with wine either (there are videos on youtube of the benchmark working but I have never seen the full game working under wine with or without Proton). Attached is a log produced by Proton during execution.
