Hello !
First, I would like to apologize because I'm french, and my english must not be really good. If I'm here, it's because the french site can't give me a good answer to my problem...
Here's my problème (I'll make a translation, but sorry for the mistakes, If you feel good enough with french, here's the original message : http://h30478.www3.hp.com/t5/Ordinateurs-portables-Affichage-et-graphiques/Hp-Pavilion-AMD-Radeon-HD-8670M-commutable-non-reconnu/td-p/404748 ) :
I've a laptop HP Pavilion 17-e084sf, with a graphic card AMD Radeon HD 8670M, and a CPU Intel i5, running on Windows 8.1.
Normaly : the processor's chipset (intel HD graphics 4000) is running when I use light applications,and the AMD should run when I use applications like video games.
But : whatever I do, I absolutly can't make the AMD card running for any application !!!
Starcraft 2 is running on the Intel chipset, because he doesn't recognize the AMD card. And all other applications can't run on the AMD card neither ! Even when I try configuring the switchable graphisms, and select "high performance" for the applications I want.
Even if I turn off the intel HD graphics 4000, the AMD doesn't run, I have "basis microsoft drivers" or something like that...
For exemple, I have an executable battlenet (for the betas) who check the computer, and diplay the configuration : it say that my graphic card is the Intel chipset, not the AMD !
If I turn off the Intel HD, it display 'basis microsoft drivers", but never the AMD.
If I go in "computer management" (where I can see all the material), I can see the two card, the AMD and the Intel.
In the BIOS, I have no option for switching between fixed or dynamic about the graphic card.
The drivers were from the manufacturer site :http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4158&lc=fr&cc=fr&dlc=fr&sw_lang=&product=6422
I've tried more recent or older drivers, but nothing work.
I've also tried modded drivers, from leshcat.net , but it doesn't work neither...
I can't make my computer use ONLY the AMD card, whatever I do.
Sorry for my english, I hope it's understandable.
Thanks for your attention and your help
