I want to change my hardware acceleration on windows vista!!?

I went onto Personalize, Display Settings, Advanced Settings, Troubleshoot. But I cannot click on the 'Change Settings' button. It says below 'Your current display driver does not allow changes to be made to hardware acceleration settings.'

How can I get pass that?I want to change my hardware acceleration on windows vista!!?
This is driver dependent and can only be changed with a different driver. In the system settings, you can try Advanced, Peformance, Settings you can make some changes. This may help with what you want.
