Catalyst is a driver, you can't turn it on, it will run automatically as soon as it is turned on. For example, it is gasoline for cars. You have an engine (graphics card) but you can't start it without oil. At this time, gasoline is equivalent to a catalyst (driver), which can make your car start and drive away.

CCC is to set some attributes of the graphics card. For example, 3D game screen settings. Overclocking, fan speed, etc.

AMD feature manager, you don't have to worry about him, you don't have to use this thing. This is management software, you don't need to use it.

Vision engine is the setting of AMD processor (CPU). Your processor should be Intel's. It's normal without this thing. You can only use CCC now. Pay attention to overclocking Don't overclock if nothing happens. The graphics card will be broken.
