Hello. I have a laptop hp pavilion ... It is worth 2 video cards. Radeon r4 and Radeon Radeon r7. Windows 8.1 x64. As much as I tried to install the drivers R7 is not working. The Device Manager is displayed correctly but in games much low FPS. Please help me with the drivers and install them. We are sorry if there are errors in the text, I just translate from Russian. Thank you.
