I have a laptop with amd radeon 535dx but the entegrated GPU, which is AMD Radeon R7 Graphics, is being used even in graphic demanding programs and games. I set it to work in high performance mode from Radeon Additional Settings but it still uses the entegrated GPU. I don't think the problem is caused by the applications. What should I try. Also, should I use the GPU driver which I download from HP support or the ones that I can download for my AMD website, because the name of GPu changes from 535dx to M340. Thank you.
