Hi all. I have HP ENVY 17t notebook pc, Intel core i7-4710HQ CPU, Intel HD graphics 4600. i just got this laptop recently and seems that i have issue with graphics card. at the time i got it everything was going smooth..but now my fps dropped really bad. 3D mark showed really bad results on GPU even on lowest setting while CPU is fine. I just updated all my drivers from official website. Can someone suggest something?
