Make sure you have the latest version of Catalyst (ATI Graphics Card drivers), and, if/when you do, find out about how to import Smartshaders into the ATI Control Panel. Then, you can simply choose from the SmartShader list inside of the ATI CP.
(Note: Sometimes I find some graphics plugins aren't affected by SmartShaders, but it might just be my Catalyst version >.>)
Btw, you do have at least a Radeon, don't you?
