1. you could add step for amd duo core processors users to download duo core optimizier. it bumps fps for like 20-30 + for them.
2.next thing : start > services.msc > and deactivate ( turn off )
themes ( the theme for windows) - yes it turns off the theme in windows, but gives 5-10 fps boost
3. windows tends to slow down when you have a lot of files in your desktop ( the files inside catalogues in the desktop counts too ). good thing is to put those files inside hdd drive, and only put shortcut into your desktop. it could improve your fps from 0 - 10 + , depends how much files you had on desktop.
