Hi, I installed my MacBook Pro 15.4" Retina with Windows 8.1 64bit. But now it doesnt detect my AMD GPU and all games dont really run! I have the latest Bootcamp drivers. When I want to open my AMD Catalyst panel it says it has nothing to configure in an alert prompt and then closes again. In my device manager list I only find "Micorsoft Basic Display Adapter" under GPU. In "dxdiag" via Execute I also only see the Iris standard GPU but not my AMD... How can I get it? MacBook Pro (Retina, 15-inch, Mid 2015), Windows 8, 64bit My battery mode is on high performance, etc.
