HD8670 , Installed intel drivers , then the amd ones. Set everything to highest possible. Even set minimum processor state to %100 at advanced settings of power management. I tried both plugged and unplugged. Tried 10 different games. Some of them uses steam , some of them dont. But i cant solve the problem. I tried a 2006 game disabling aa , shadows , reflections , texture filter. But still 25-30 fps. I took a look at the log files of games , and saw what? games are using intel graphics. My pc is saying me that everyting is fine about my graphics card. But its not. On youtube , i saw how my games work with onboard gpu and realised that , that videos was exactly like my PC's performance. I tried everything! Bios was no use , it has no option about graphics.
