When I launch the game from steam or from the folder its in, it starts out as a white full screen then it turns into a small screen on the top left corner. The sound works and picture works but its not showing the whole screen, all i see is something about a dlc but it wont go full screen and it doesnt respond to my commands.

Greetings,
