Game did not start out of the box. Reverted to Proton 7.0-4, was able to load config. Disabled movies and set resolution to monitor native, game loaded from there with no issues.

To fix game not recognizing controller: Navigate to the game's local files (Manage > Browse Local Files). Right click on "DX9_Config.exe" > "Open with other application" > Wine Windows Program Loader. In Config, navigate to the Input tab > select controller > check "Enable gamepad" > Update. Controller should now be recognized and useable when launching through Steam.
