Hi there, just purchased and downloaded Gothic 3, but when trying to launch the game I just get at floating square on a black background with the message "Not optimum mode - recommended mode: 1080x1024 60hz" (which is the mode I'm using). My videocard is ATI Radeon HD 4800-series. The music comes through just fine. Any suggestions?

Managed to solve the problem by setting the "3D Refresh Rate Override"-option in my video card control panel at "Same as desktop".
