Game starts up without a hitch. However, it crashes after you start the game, before the intro video. I suspect my issue has to do with running Nvidia's PhysX on an AMD GPU. This should work on Windows, however, so the problem is, more than likely, an unknown tweak that is needed. I tried installing PhysX manually, and the installer claims it is already installed. I tried installing PhysX with protontricks, and protontricks claims PhysX is already installed. I tied uninstalling PhysX and then manually running the PhysX installer to reinstall. All to no avail.
