dual AMD graphics and bad performance (HP laptop)

[compufreek]

Hello !
i own a hp laptop 17-f002sm with a8 processor with r5 graphics and a main r7 m260 graphics card. before i bought the laptop i watched a few tests on youtube and games run ok with the mentioned card ... when the laptop came i tested diablo 3 on minimum settings (even resolution ) and it had around 15 - 25 fps (unplayable).
I started to play around with drivers and such with no luck... so i tried a program called furmark and no matter what setting i choose high or low end i always get the same FPS and the program says that gpu1 is r5 graphics card (with no specific name ) and open gl is rendered by r7 m260 i have no clue what is going on but the problem is that even if the m260 (2gb) is bad graphic card it should not render diablo 3 on low at 15 FPS average (as my friend's asus t100 tablet is running it at 25- 35 fps without a dedicated graphhic card )

annyone has anny advice ?

i have tried the HP drivers, updated bios and AMD drivers but no difference, if i disable graphic card i get error and dxdiag is always saying i have r5 graphic car no matter the setting and so is furmark

go in the bios and disable the r5 gpu

Hp has limited bios and i even read somewhere that the cards cannot be run on their own ... i managed to set fur mark so it only says r5 and then and the loss is 1 -2 fps i dont get it ....i guess im sending this back as it is possibli the worst laptop i have ever seen ... and then never aggain HP -.- (my friend bought a gaming laptop and the graphic card only works with HP's 3 yrold drivers .... original driver from amd does not work at all which is unaceptable for a gaming laptop )
