I have an A10-7850k and an HIS R7 250 set up in Dual Graphics, but now I can't get Mantle to work for benchmarking. Using them seperately everything works fine but together pretty much everything just blows up when activating Mantle (Thief, Star Swarm, etc.). Also when I install the drivers I have nothing but problems and I need to do a little fangling for them to install properly. Is this a driver issue or is there a deeper problem with my comp?
In TL;DR form:
1) Mantle doesn't work when I use Dual Graphics, any clue why?
2) What's the best way to instal Dual Graphics without install warnings/errors?
I'm running 14.4 WHQL and Windows 8.1 (fresh install, the problem also occured before formatting), I had to RMA my older memory and the current memory is fine (ran with MemTest).
