Symptoms

Under the latest Proton stable (6.3-4) the game doesn't fully launch only showing it's launcher and an error message, the error message says the following; "DX11 feature level 10.0 is required to run the engine". After closing the error the game is killed.

Under Proton Experimental the game launches however it freezes after showing the introduction videos. Some (not all) introduction video's display as "TV test" images due to them requiring Microsoft Media Foundation.

Reproduction

1. Launch the game
2. Wait for above mentioned symptoms to appear

Start by reproducing the game with Proton 6.3-4 and Proton Experimental, then inspect the attached steam-1253190-proton_6.3-4.log and steam-1253190-proton_experimental.log files. Done means the game launches past the introduction videos without the DX11 feature-level error or freeze, and the videos display correctly.
