Let's take a look at the glxgears score. Before I installed the driver, it was about 300. After I installed the driver, it was about 5000. Many graphics cards need to be driven to enable 3D desktops. The built-in video card driver of Fedora9 has relatively poor functions and is not well developed. Coupled with AMD (ATI)'s perfunctory attitude in Developing Linux drivers, the atigraphics card driver provided by Fedora is very bad, it is easy to see pro
A little understanding of the graphics card friends will not unfamiliar ATI graphics card.

. The traditional pixel assembly line consists of several groups of PSU (pixel shaderUnit) + TMU + drop. As a result, the traditional GPU generates polygon from vertex units, and the pixel assembly line is responsible for pixel rendering and output. The pixel assembly line needs to be described as follows: Although traditionalThe pipeline is considered to be 1psu + 1tmu + 1rop, but this ratio is not constant. For example, in the radeonx1000 (excluding x1800) series, it is widely regarded as the
