Due to reasons involving the performance of some of my steam games I have been trying to change the power settings of my graphics card to allow better 3D performance. After looking online I was advised to install AMD Catalyst as it would give me access to the power settings. However after installing several versions none of them have the power option. My graphics card is a radeon HD 5450 and running windows 7. Which version of the software do I need to install to gain access to the power settings?
