Last time when I right-clicked the desktop, there would be two options with the "AMD Catalyst" logos beside them in the menu, one of them was graphics properties or something like that which opens up a window that allows me to set 3D settings such as mipmapping, 3D quality and stuff like that to optimise game performance, but now it is gone and when I try to run the AMD Vision Engine control Center, it says CCC.exe not found. Please help!
