How to use discrete graphics on linux?

[ViviamJone]

As a newcomer to Linux, I recently installed Zorin OS on my HP Pavilion G62231tx Laptop, which features both an AMD Radeon 7670M discrete graphics card and Intel HD graphics. However, the system defaults to using the Intel graphics card, and although I searched the additional drivers section, no options were found.

I am curious if there is a way to install the necessary drivers for the echatrandom chatrandom discrete graphics card, and if it is necessary to do so. While the system is not currently experiencing any noticeable lag, I would like to take advantage of the additional graphics card if possible.

Any assistance you could offer would be greatly appreciated.
