AMD Catalyst

AMD Catalyst is a set of drivers for AMD Radeon graphics cards. This file not only contains the "bare" drivers for the graphics cards, but also offers a lot of additional programs and components that cater to extensive 3D graphics setup (which is most often seen in games), offer advanced driver setup options, and much more.

This package includes:

Display Driver (the driver itself for AMD Radeon graphics cards)
Catalyst Control Center (control center for setting all sorts of parameters that affect the final graphics rendering)
