I have an HP dv6 laptop with an an AMD Radeon 7690m XT dedicated Graphics card. The PC came with windows 7 but I recently upgraded to win 8.
I updated the drivers to the most recent Catalyst directly from AMD (HP simply does NOT provide graphic drivers for win 8), and the card seems to work fine, although it now reports as a Radeon HD 6700M series. That is OK since I read the Catalyst drivers just do that because the 7690m is just a custom version of a 6770 made by HP. that is not an issue.
The problem is that some games and windows itself seem to sometimes only "see" the integrated card (intel HD graphics 3000) instead of the dedicated GPU, for example, the direct X diagnostic tool, shows only the intel. The same when i see the properties of my display (in "advanced" under "display resolution" options.)
When i check device manager, i DO see both cards, also when I use GPU-Z, but why some applications seem to only see the intel one instead of the dedicated one?
I already changed an option in my BIOS and changed the "dynamic" setting, to "fixed", and that is supposed to make precisely what I want, that is, to make windows only see the dedicated card all the time, instead of switching cards depending in the application.
In fact, that option worked just fine under win 7, but now in win 8.
So, is there a way of making windows IGNORE the integrated card and just to care about the dedicated one? I tried disabling the intel card under device manager, but that only makes windows reporting a "microsoft basic display driver" under Direct X diag, instead of reporting the dedicated AMD card, which otherwise, the device manager reports working just ok (and with no driver issues).
Any ideas? Anyone has had this same probem under windows 8 with amd cards for laptops?
